Question: How can the error be resolved? Running pip install zipline[all] gives the same error...
The problem here is the line 292 (Using Python 3.4.3 here) in $python_install_prefix/Lib/distutils/msvc9compiler.py which says:
VERSION = get_build_version()
This only checks for the MSVC version that your python was built with. Just replacing this line with your actual Visual Studio version, eg. 12.0 for MSVC2013
VERSION = 12.0
will fix the issue.
UPDATE: Turns out that there is a good reason why this version is hardcoded. MSVC C runtime is not required to be compatible between major versions. Hence when you use a different VS version you might run into runtime problems. So I advise to use VS 2008 (for Python 2.6 up to 3.2) and VS2010 for (Python 3.3 and later) until this issue is sorted out.
Binary compatibility will arrive with VS 2015 (see here) along with Python 3.5 .
For Python 2.7 users Microsoft released a special Microsoft Visual C++ Compiler for Python 2.7 which can be used without installing the whole VS 2008.
You could use ol' good easy_install zipline instead.
easy_install isn't pip but one good aspect of it is the ability to download and install binary packages too, which would free you for the need having VC++ ready. This of course relies of the assumption that the binaries were prepared for your Python version.
UPDATE:
Yes, Pip can install binaries now!
There's a new binary Python archive format (wheel) that is supposed to replace "eggs". Wheels are already supported by pip. This means you'll be able to install zipline with pip without compiling it as soon as someone builds the wheel for your platform and uploads it to PyPI.
If you are getting this error on Python 2.7 you can now get the Microsoft Visual C++ Compiler for Python 2.7 as a stand alone download.
If you are on 3.3 or later you need to install Visual Studio 2010 express which is available for free here: https://www.visualstudio.com/downloads/download-visual-studio-vs#d-2010-express
If you are 3.3 or later and using a 64 bit version of python you need to install the Microsoft SDK 7.1 that ships a 64 bit compiler and follow the directions here Python PIP has issues with path for MS Visual Studio 2010 Express for 64-bit install on Windows 7
First, you should look for the file vcvarsall.bat in your system.
If it does not exist, I recommend you to install Microsoft Visual C++ Compiler for Python 2.7. This will create the vcvarsall.bat in "C:\Program Files (x86)\Common Files\Microsoft\Visual C++ for Python\9.0" if you install it for all users.
The problem now is in the function find_vcvarsall(version) in the C:/Python27/Lib/distutils/msvc9compiler.py module, which is looking for the vcvarsall.bat file.
Following the function calls you will see it is looking for an entry in the registry containing the path to the vcvarsall.bat file. It will never find it because this function is looking in other directories different from where the above-mentioned installation placed it, and in my case, the registry didn't exist.
The easiest way to solve this problem is to manually return the path of the vcvarsall.bat file. To do so, modify the function find_vcvarsall(version) in the msvc9compiler.py file with the absolute path to the vcvarsall.bat file like this:
def find_vcvarsall(version):
return r"C:\Program Files (x86)\Common Files\Microsoft\Visual C++ for Python\9.0\vcvarsall.bat"
This solution worked for me.
If you already have the vcvarsall.bat file you should check if you have the key productdir in the registry:
(HKEY_USERS, HKEY_CURRENT_USERS, HKEY_LOCAL_MACHINE or HKEY_CLASSES_ROOT)\Software\Wow6432Node\Microsoft\VisualStudio\version\Setup\VC
Where version = msvc9compiler.get_build_version()
If you don't have the key just do:
def find_vcvarsall(version):
return <path>\vcvarsall.bat
To understand the exact behavior check msvc9compiler.py module starting in the find_vcvarsall(version) function.
Simply because you don't have c++ compiler installed there in your machine, check the following
Download Microsoft Visual C++ 2008 from this page. That is a generally useful page anyway, so you should probably bookmark it. For Python 3.3+ use MS Visual C++ 2010.
Install it.
Open Windows explorer (the file browser) and search for the location of ‘vcvarsall.bat’ and cut it to your clipboard.
run regedit from the Windows start key. You will need admin privilges.
Add a registry entry to
HKEY_LOCAL_MACHINE\Software\Wow6432Node\Microsoft\VisualStudio\9.0\Setup\VC\ProductDir (64 bit Windows) or
HKEY_LOCAL_MACHINE\Software\Microsoft\VisualStudio\9.0\Setup\VC\ProductDir (32 bit)
as described here.
Hint: 0.9 in the registery directory is the currently installed version of your visual studio, if you running VS 2013, you have to find the path HKEY_LOCAL_MACHINE\Software\Wow6432Node\Microsoft\VisualStudio\12.0....
At the Windows start key, type cmd to get a command shell. If you need to, go to your virtual environment and run activate.bat.
pip install or whatever you use to install it.
You need to have Visual Studio's bin dir in your path. Pip install is trying to compile some C code.
I spent hours researching this vcvarsall.bat as well. Most answers on SO focus on Python 2.7 and / or creating workarounds by modifying system paths. None worked for me. This solution worked out of the box for Python 3.5 and (I think) is the "correct" way of doing it.
See this link -- it describes the Windows Compilers to use for different versions of Python: https://wiki.python.org/moin/WindowsCompilers#Microsoft_Visual_C.2B-.2B-_14.0_standalone:_Visual_C.2B-.2B-_Build_Tools_2015_.28x86.2C_x64.2C_ARM.29
For Python 3.5, download this: https://www.microsoft.com/en-us/download/details.aspx?id=49983
For me, I had to run C:\Program Files (x86)\Microsoft Visual C++ Build Tools\Visual C++ x64 Native Build Tools Command Prompt for it to work. From that command prompt, I ran "pip install django_compressor" which was the particular package that was causing me an issue, and it worked perfectly.
Hope this saves someone some time!
Thanks to "msoliman" for his hint, however his answer doesn't give clear solution for those who doesn't have VS2010
For example I have VS2012 and VS2013 and there are no such KEYs in system registry.
Solution:
Edit file: "[Python_install_loc]/Lib/distutils/msvc9compiler.py"
Change on line 224:
productdir = Reg.get_value(r"%s\Setup\VC" % vsbase,
"productdir")
to:
productdir = "C:\Program Files (x86)\Microsoft Visual Studio [your_vs_version(11/12...)]\VC"
and that should work
If you are trying to install matplotlib in order to work with graphs on python. Try this link.
https://github.com/jbmohler/matplotlib-winbuild.
This is a set of scripts to build matplotlib from source on the MS Windows platform.
To build & install matplotlib in your Python, do:
git clone https://github.com/matplotlib/matplotlib
git clone https://github.com/jbmohler/matplotlib-winbuild
$ python matplotlib-winbuild\buildall.py
The build script will auto-detect Python version & 32/64 bit automatically.
I appreciate this might not be the answer to resolving on 3.4 but I tried a huge variety of things to fix this on 3.4 and thought this might be useful if someone is time pressed or doesn't have the know-how to correct it (in my case, work demands).
With exactly the same setup, I found that my installation problems only happened with Python 3.4. When I changed to 2.7, all my issues seemed to be resolved.
We have a rather overzealous security setup though so I'm going to try the same on my home version (still 3.4) and see if I have any more joy. My inclination is that my VS version has somehow been restricted and the answers above should help. If I find anything more tonight I'll add further detail.
This is my first reply, not the most technical I'm afraid!
I have tried everything given and the tutorials all point in the same direction about using mingw as a compiler in python instead of visual c++.
I do have visual c++ and mingw both. Problem started coming when I wanted to install using pip. It always gave Unable to find vcvarsall.bat
So as per suggestions I created a file distutils.cfg under the following path c:/python27/Lib/distutils/ and added the following two lines:
[build]
compiler=mingw32
However, this file has no effect whatsoever. The same error still exists while using pip. I am trying to install numpy by the way currently although the error came earlier also.
Cost me several hours to figure this out but now works like a charm.
I am on Windows 64bit and using a scientific Python distribution Enthought Canopy.
Ensure you have installed MinGW and the Compilers you need (C, C++, Fortran..)
Add C:\MingW\bin to your PATH in Environment variables
In C:\Users\MyName\AppData\Local\Enthought\Canopy32\App\appdata\canopy-1.6.2.3262.win-x86\Lib\distutils, create with notepad++ or similiar a new file distutils.cfg
Write and save:
[build]
compiler = mingw32
[build_ext]
compiler = mingw32
Difficult Solution (Building using the C/C++ compiler)
Are you on Windows 32bit or 64bit? Are you specifying the build when you're compiling? For example, do the following in your shell or bash:
python setup.py build --compiler==mingw32
python setup.py install
Easier Solution (Use pre-built binaries)
If you don't have to compile the program, you can use the unofficial Windows binaries from here
Do you happen to use virtualenv as well?
Anyway, use Microsoft Visual C++ Compiler for Python 2.7
and a newer setuptools. The one bundled with virtualenv (3.6) does not support this compiler.
pip install "setuptools>=6.0"

I installed distribute and pip using the links I have just given. I also installed the Microsoft Visual C++ 2008 redistributable package. However when I try to use pip.exe I get
error: Unable to find vcvarsall.bat
How can I fix this?
Installing the Microsoft Visual C++ 2008 Redistributable Package is not sufficient to compile packages. You need to install a compiler, not just the support files.
There are three ways to do this:
Install Visual C++.
Use mingw's port of gcc instead of Visual C++.
Use cygwin's port of gcc instead of either, and a cygwin build on Python instead of the native one.
If you want to go with option 1, you need to install Visual C++ itself. The free version should work just as well as the paid version, as long as you're not going to build binary packages to redistribute to others. Unfortunately, I'm not sure where to find the 2008 version anymore. As of May 2013, the download page only has 2010 and 2012.
When you install this, it will create a batch file called vcvarsall.bat (not vcvarshall.bat!), and give you the option of putting that batch file in your PATH. Running that batch file sets up a DOS prompt for building with that version of Visual C++. (This is handy if you have multiple versions of Visual C++, or other compilers, around.) If you skip that option, you will have to do it manually.
This question shows how to use a newer Visual Studio with older Python, and also shows how to point distutils at a vcvarsall.bat that's not on your PATH, and has links to a whole lot of other relevant questions and blog posts.
Many people find option 2 simpler. Install mingw, modify your PATH in the environment to include C:\MinGW\bin (or wherever you choose to install it), and pass -c mingw32 whenever you run a setup.py script.
The problem is that it's not as clearly documented how to tell easy_install and pip to use mingw instead of VC++. To do that, you need to find or create a distutils.cfg file, find or create a [build] section within it, and add compiler=mingw32. Not too hard. This blog post looks like it explains things pretty well, or see this answer.
Option 3 is by far the simplest. Install cygwin, tell it to install the Python and gcc packages, and you're done.
The problem is that you don't have native Windows Python, you have a Unix Python running in a fake Unix environment on top of Windows. If you like Cygwin, you'll love this; otherwise, you won't.
You'll receive such error only for packages (or one of package's dependencies) that has CPython extensions. Pip internally:
downloads the source
runs distutils python setup install
install prepares setup files and tries to build CPython extensions in windows environment
windows environment calls MS Visual Studio vcvarsall.bat script which setups DOS environment variables to enable MS Visual Studio's C compiler in the shell
if vcvarsall.bat is not found - you'll get this message
Usual solution
For python libraries which have CPython extensions that are portable on windows, it is usual to have windows binary package, which are downloadable from pypi or library web site.
In such cases it is more suitable (and painless) to install library by downloading and running windows binary package.
There is a feature request for pip to Add support for installation of binary distutils packages on Windows.
New way to do it - wheels
Thanks to comment from #warren-p: That feature request has been superseeded by Wheels support in PIP.
Official description: A wheel is a ZIP-format archive with a specially formatted filename and the .whl extension.
As I have understood, if there is windows binary package with extension .whl then start by installing wheel first:
# Make sure you have the latest pip that supports wheel
pip install --upgrade pip
pip install wheel
and then install .whl like this:
pip install full-path-or-url-to-your-library.whl

I've read every other google source and SO thread, with nothing working.
Python 2.7.3 32bit installed on Windows 7 64bit. Download, extracting, and then trying to install PyCrypto results in "Unable to find vcvarsall.bat".
So I install MinGW and tack that on the install line as the compiler of choice. But then I get the error "RuntimeError: chmod error".
How in the world do I get around this? I've tried using pip, which gives the same result. I found a prebuilt PyCrypto 2.3 binary and installed that, but it's nowhere to be found on the system (not working).
Any ideas?
If you don't already have a C/C++ development environment installed that is compatible with the Visual Studio binaries distributed by Python.org, then you should stick to installing only pure Python packages or packages for which a Windows binary is available.
Fortunately, there are PyCrypto binaries available for Windows:
http://www.voidspace.org.uk/python/modules.shtml#pycrypto
UPDATE:
As #Udi suggests in the comment below, the following command also installs pycrypto and can be used in virtualenv as well:
easy_install http://www.voidspace.org.uk/python/pycrypto-2.6.1/pycrypto-2.6.1.win32-py2.7.exe
Notice to choose the relevant link for your setup from this list
If you're looking for builds for Python 3.5, see PyCrypto on python 3.5
After years and years, python finally agreed for a binary disribution called wheel which allows to install even binary extensions on Windows without having a compiler with simple pip install packagename. There is a list of popular packages with their status. Pycrypto is not there yet, but lxml, PySide and Scrapy for example.
Edited Nov 2015: pip uninstall pycrypto & pip install pycryptodome. It is a pycrypto fork with new features and it supports wheel. It replaces pycrypto, so existing code will continue to work (see https://pycryptodome.readthedocs.org/en/latest/src/examples.html)
Microsoft has recently recently released a standalone, dedicated Microsoft Visual C++ Compiler for Python 2.7. If you're using Python 2.7, simply install that compiler and Setuptools 6.0 or later, and most packages with C extensions will now compile readily.
For VS2010:
SET VS90COMNTOOLS=%VS100COMNTOOLS%
For VS2012:
SET VS90COMNTOOLS=%VS110COMNTOOLS%
then Call:
pip install pyCrypto
In general
vcvarsall.bat is part of the Visual C++ compiler, you need that to install what you are trying to install. Don't even try to deal with MingGW if your Python was compiled with Visual Studio toolchain and vice versa. Even the version of the Microsoft tool chain is important. Python compiled with VS 2008 won't work with extensions compiled with VS 2010!
You have to compile PyCrypto with the same compiler that the version of Python was compiled with. Google for "Unable to find vcvarsall.bat" because that is the root of your problem, it is a very common problem with compiling Python extensions on Windows.
There is a lot of information and a lot to read to get this right on whatever system you are on with this link.
Beware using Visual Studio 2010 or not using Visual Studio 2008
As far as I know the following is still true. This was posted in the link above in June, 2010 referring to trying to build extensions with VS 2010 Express against the Python installers available on python.org.
Be careful if you do this. Python 2.6 and 2.7 from python.org are
built with Visual Studio 2008 compilers. You will need to link with
the same CRT (msvcr90.dll) as Python.
Visual Studio 2010 Express links with the wrong CRT version:
msvcr100.dll.
If you do this, you must also re-build Python with Visual Studio 2010
Express. You cannot use the standard Python binary installer for
Windows. Nor can you use any C/C++ extensions built with a different
compiler than Visual Studio 2010 (Express).
Opinion: This is one reason I abandoned Windows for all serious development work for OSX!
PyCryptodome is an almost-compatible fork of PyCrypto with Windows wheels available on pypi.
You can install it with a simple:
pip install pycryptodome
The website includes instructions to build it from sources with the Microsoft compilers too.
I have managed to get pycrypto to compile by using MinGW32 and MSYS. This presumes that you have pip or easy_install installed.
Here's how I did it:
1) Install MinGW32. For the sake of this explanation, let's assume it's installed in C:\MinGW. When using the installer, which I recommend, select the C++ compiler. MSYS should install with MinGW
2) Add c:\mingw\bin,c:\mingw\mingw32\bin,C:\MinGW\msys\1.0, c:\mingw\msys\1.0\bin and c:\mingw\msys\1.0\sbin to your %PATH%. If you aren't familiar, this article is very helpful.
3) From the search bar, run msys and the MSYS terminal will open. For those familiar with Cygwin, it works in a similar fashion.
4) From within the MSYS terminal pip install pycrypto should run without error after this.
For Windows 7:
To install Pycrypto in Windows,
Try this in Command Prompt,
Set path=C:\Python27\Scripts (i.e path where easy_install is located)
Then execute the following,
easy_install pycrypto
For Ubuntu:
Try this,
Download Pycrypto from "https://pypi.python.org/pypi/pycrypto"
Then change your current path to downloaded path using your terminal and user should be root:
Eg: root#xyz-virtual-machine:~/pycrypto-2.6.1#
Then execute the following using the terminal:
python setup.py install
It's worked for me. Hope works for all..
For those of you looking for python 3.4 I found a git repo with an installer that just works. Here are the direct links for x64 and x32
Try just using:
pip install pycryptodome
or:
pip install pycryptodomex
Source: https://pypi.python.org/pypi/pycryptodome
If you are on Windows and struggling with installing Pycrypcto just use the:
pip install pycryptodome.
It works like a miracle and it will make your life much easier than trying to do a lot of configurations and tweaks.
It's possible to build PyCrypto using the Windows 7 SDK toolkits. There are two versions of the Windows 7 SDK. The original version (for .Net 3.5) includes the VS 2008 command-line compilers. Both 32- and 64-bit compilers can be installed.
The first step is to compile mpir to provide fast arithmetic. I've documented the process I use in the gmpy library. Detailed instructions for building mpir using the SDK compiler can be found at sdk_build
The key steps to use the SDK compilers from a DOS prompt are:
1) Run either vcvars32.bat or vcvars64.bat as appropriate.
2) At the prompt, execute "set MSSdk=1"
3) At the prompt, execute "set DISTUTILS_USE_SDK=1"
This should allow "python setup.py install" to succeed assuming there are no other issues with the C code. But I vaaguely remember that I had to edit a couple of PyCrypto files to enable mpir and to find the mpir libraries but I don't have my Windows system up at the moment. It will be a couple of days before I'll have time to recreate the steps. If you haven't reported success by then, I'll post the PyCrypto steps. The steps will assume you were able to compile mpir.
I hope this helps.
So I install MinGW and tack that on the install line as the compiler
of choice. But then I get the error "RuntimeError: chmod error".
This error "RuntimeError: chmod error" occurs because the install script didn't find the chmod command.
How in the world do I get around this?
Solution
You only need to add the MSYS binaries to the PATH and re-run the install script.
(N.B: Note that MinGW comes with MSYS so )
Example
For example, if we are in folder C:\<..>\pycrypto-2.6.1\dist\pycrypto-2.6.1>
C:\.....>set PATH=C:\MinGW\msys\1.0\bin;%PATH%
C:\.....>python setup.py install
Optional: you might need to clean before you re-run the script:
`C:\<..>\pycrypto-2.6.1\dist\pycrypto-2.6.1> python setup.py clean`
Go to "Microsoft Visual C++ Compiler for Python 2.7" and continue based on "System Requirements" (this is what I did to put below steps together).
Install setuptools (setuptools 6.0 or later is required for Python to automatically detect this compiler package)
either by: pip install setuptools
or download "Setuptools bootstrapping installer" source from, save this file somwhere on your filestystem as "ez_python.py" and install with: python ez_python.py
Install wheel (wheel is recommended for producing pre-built binary packages). You can install it with: pip install wheel
Open Windows elevated Command Prompt cmd.exe (with "Run as administrator") to install "Microsoft Visual C++ Compiler for Python 2.7" for all users. You can use following command to do so: msiexec /i C:\users\jozko\download\VCForPython27.msi ALLUSERS=1 just use your own path to file: msiexec /i <path to MSI> ALLUSERS=1
Now you should be able to install pycrypto with: pip install pycrypto
My answer might not be related to problem mention here, but I had same problem with Python 3.4 where Crypto.Cipher wasn't a valid import. So I tried installing PyCrypto and went into problems.
After some research I found with 3.4 you should use pycryptodome.
I install pycryptodome using pycharm and I was good.
from Crypto.Cipher import AES
This probably isn't the optimal solution but you might download and install the free Visual C++ Express package from MS. This will give you the C++ compiler you need to compile the PyCrypto code.
So I install MinGW and tack that on the install line as the compiler of choice. But then I get the error "RuntimeError: chmod error".
You need to install msys package under MinGW
and add following entries in your PATH env variable.
C:\MinGW\bin
C:\MinGW\msys\1.0\bin [This is where you will find chmod executable]
Then run your command from normal windows command prompt.
Step 1: Install Visual C++ 2010 Express from
here.
(Do not install Microsoft Visual Studio 2010 Service Pack 1 )
Step 2: Remove all the Microsoft Visual C++ 2010 Redistributable packages from Control Panel\Programs and Features. If you don't do those then the install is going to fail with an obscure "Fatal error during installation" error.
Step 3: Install offline version of Windows SDK for Visual Studio 2010 (v7.1) from here.
This is required for 64bit extensions. Windows has builtin mounting for ISOs like Pismo.
Step 4: You need to install the ISO file with Pismo File Mount Audit Package. Download Pismo from here
Step 5: Right click the downloaded ISO file and choose mount with Pismo. Thereafter, install the Setup\SDKSetup.exe instead of setup.exe.
Step 6a: Create a vcvars64.bat file in C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin\amd64 by changing directory to C:\Program Files (x86)\Microsoft Visual Studio version\VC\ on the command prompt.
Type command on the command prompt:
cd C:\Program Files (x86)\Microsoft Visual Studio version\VC\r
Step 6b:
To configure this Command Prompt window for 64-bit command-line builds that target x86 platforms, at the command prompt, enter:
vcvarsall x86 Click here for more options.
Step 7: At the command prompt, install the PyCrypto by typing:
C:\Python3X>pip install -U your_wh_file
I had Pycharm for python.
Go to pycharm -> file -> setting -> project interpreter
Click on +
Search for "pycrypto" and install the package
Note: If you don't have "Microsoft Visual C++ Compiler for Python 2.7" installed then it will prompt for installation, once installation finished try the above steps it should work fine.
I'm trying to install said library for use with Python. I tried downloading the executable installer for Windows, which runs, but says it doesn't find a Python installation. Then tried registering (http://effbot.org/zone/python-register.htm) Python, but the script says it can't register (although the keys appear in my register).
Then I tried downloading the source package: I run the setup.py build and it works, but when I run setup.py install it says the following:
running install
running build
running build_py
running build_ext
building '_imaging' extension
error: Unable to find vcvarsall.bat
What can I do?
UPDATE (May 2014): Like said by some comments and answers, PIL is currently unmantained, and the way to go now is to use Pillow (https://pypi.python.org/pypi/Pillow/, pip install pillow).
I found a working win7 binary here: Unofficial Windows Binaries for Python Extension Packages It's from Christoph Gohlke at UC Irvine. There are binaries for python 2.5, 2.6, 2.7 , 3.1 and 3.2 for both 32bit and 64 bit windows.
There are a whole lot of other compiled packages here, too.
Be sure to uninstall your old PILfirst.
If you used easy_install:
easy_install -mnX pil
And then remove the egg in python/Lib/site-packages
Be sure to remove any other failed attempts. I had moved the _image dll into Python*.*/DLLs and I had to remove it.
I've just had the same problem (with Python 2.7 and PIL for this versions, but the solution should work also for 2.6) and the way to solve it is to copy all the registry keys from:
HKEY_LOCAL_MACHINE\SOFTWARE\Python
to
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Python
Worked for me
solution found at the address below so credits should go there:
http://effbot.slinkset.com/items/Adding_Python_Information_to_the_Windows_Registry
Compiling PIL on Windows x64 is apparently a bit of a pain. (Well, compiling anything on Windows is a bit of a pain in my experience. But still.) As well as PIL itself you'll need to build many dependencies. See these notes from the mailing list too.
There's an unofficial precompiled binary for x64 linked from this message, but I haven't tried it myself. Might be worth a go if you don't mind the download being from one of those slightly dodgy file-upload sites. Other than that... well, you could always give up and instead the 32-bit Python binary instead.
If you installed a win64 python, you need a win64 PIL. The official PIL download site only has win32, as far as I can tell. The win32 installer will not see your 64-bit python installation.
No amount of tinkering with permissions or redistributables will fix this. You could use the win32 python instead (the Win64 python is mutant anyhow; Microsoft decided that C 'long' should be 32 bits in their 64-bit world, so python 'ints' are only 32 bits in Win64 python).
Since sizeof(long)!=sizeof(ptr) in win64, porting C extensions can be problematic, and will not be the same as porting them to linux 64. E.g. it seems that Win64 numpy is experimental/broken whereas linux64 numpy has been fine for years. My recommendation is if you use win64, stick with win32 python. If you want 64-bit python use linux.
I think I had a similar problem in the past, with another python library. I believe that it was a windows permission issue. Try adding "Users" to your python directory, and give them full access.
Make sure you have the Visual C++ Redistributable package installed on your machine.
Just got this error msg on my 32 bit Windows - I read the FAQ here: http://pythonware.com/products/pil/faq.htm and this sort of indicates that Windows is funny. Looked again at install pg and downloaded the Windows executable for Python26 # Python Imaging Library 1.1.7 for Python 2.6 (Windows only) - and the _imaging module gets installed when you run this. Should solve problem. So you can't just do the python setup.py install routine on: Python Imaging Library 1.1.7 Source Kit (all platforms) (November 15, 2009).
I was having the same problem so I decided to download the source kit and install it according to how you posted above...
Downloaded Source Kit
Opened command prompt on that folder and typed python setup.py build
Then I typed python setup.py install
It worked perfectly!
Now, some notes: when I typed python setup.py build, I saw that Microsoft Visual Studio v9.0 C compiler was being used to build everything.
So probably it's something with your compiler not correctly configured or something...
Anyways, that worked with me so thank you!
Pillow is new version
PIL-1.1.7.win-amd64-py2.x installers are available at
http://www.lfd.uci.edu/~gohlke/pythonlibs/#pil
http://www.lfd.uci.edu/~gohlke/pythonlibs/
press contrl F
type Pillow‑2.4.0.win‑amd64‑py3.3.exe
then click and downloadd the 64 bit version
Pillow is a replacement for PIL, the Python Image Library, which provides image processing functionality and supports many file formats.
Note: use from PIL import Image instead of import Image.
