I am trying to install Python 3.6.9 and am having problems.
First I downloaded Python-3.6.9-tgz, then extracted it to get Python-3.6.9.tar, then extracted that to get a folder called Python-3.6.9
This has setup.py in it. So on windows 10 I opened the command prompt and navigated to that folder and typed: setup.py install. This opens up visual studio that I already have and does nothing. Please let me know if I need to do something else.
I tried to add environmental variables but nothing has worked.
First of all: You should really just download Python 3.7.4. Python 3.7 is backwards compatible with Python 3.6.
The Python 3.6.9 release is a security-only release primarily aimed at Long-term-support Linux distributions that must continue to support 3.6.x packages. As such no binary installers are provided, and Windows users are instead expected to have upgraded to 3.7 already.
If you still feel you want to compile Python 3.6.9, then the README.rst file includes installation instructions for Unix, Linux, BSD, macOS, and Cygwin, and for Windows points you to a dedicated file:
On Windows, see PCbuild/readme.txt.
which can be found online at https://github.com/python/cpython/blob/v3.6.9/PCbuild/readme.txt. The same directory holds a batch script designed to make building Python easier on Windows. From the above documentation:
Building Python using the build.bat script
In this directory you can find build.bat, a script designed to make
building Python on Windows simpler. This script will use the env.bat
script to detect one of Visual Studio 2015, 2013, 2012, or 2010, any of
which may be used to build Python, though only Visual Studio 2015 is
officially supported.
By default, build.bat will build Python in Release configuration for
the 32-bit Win32 platform. It accepts several arguments to change
this behavior, try build.bat -h to learn more.
The setup.py script is used indirectly by the build process. Don't run it yourself.
I'm new to stack overflow. I was wondering if anybody knew if there was a .msi package for a python interpreter for python 3.5, I'm teaching a basic python class and wanted to be prepared for when it starts in a few weeks. There is a .msi packaged interpreter for 2.7 python on the official python.org downloads page but not 3.5 it seems. I am trying to use the interpreter in the community PyCharm IDE because I'm assuming most of the students will be using windows, not Linux (like I'm using). Any help would be greatly appreciated. Thank you in advance.
After Python 3.4.4 was released python.org stopped providing MSI installers for their Windows releases. Web-based, exectuable, and zipped installers are now provided for both 32-bit and 64-bit Windows releases. I'm not sure what the reason for this switch was, but an exectuable will install Python just fine. You can find Python 3.5.2 Windows executable installer at the bottom of this page.
All Python installs come with a Python interpreter. Make sure you select to add Python to your PATH during the install process. After Python finishes installing, open a Command Prompt, and type python to access the Python interpreter.
I'm using Cygwin and Python2.7 and I have already installed some third party modules (PySide, PyGame) on my computer and when I run them using the normal GUI they work fine. But when I run python inside Cygwin it doesn't recognize the modules I already have installed. I'm using Windows 7 for this. Is there anyway I can get Cygwin to recognize these libraries?
You're question is not clear (e.g. what do you mean by "the normal GUI"), but it sounds like you installed Windows versions of Python and those extensions; those binaries won't work with the Cygwin version of Python.
I have downloaded the two releases of python 2.6.8 from here http://www.python.org/getit/releases/2.6.8/ and I don't know how to install that on my Windows 7 64bit OS. Please someone help me. I searched but I can't find good tutorial.
Thanks!
2.6.8 is a source only release. Download either 2.6.6 or 2.7.3 depending on your requirements, which come with Windows installers.
If you want to install Python 2.6.8 on a Windows machine, you can do the following:
If you don't have Microsoft Visual Studio, install it: the Express edition is available here: http://www.microsoft.com/visualstudio/eng/products/visual-studio-express-products
Unzip your source code to a folder (lets call it E:\Python) and open E:\Python\PCbuild\pcbuild.sln in Visual Studio.
Set your build configuration to Debug for Win32 (available under Build => Configuration Manager.
Build your solution. You should see errors, these are related to modules for which patches were released such as zlib and sqlite. Fixing those is a little outside my expertise regarding a Python Windows install but there are patches available as I've resolved some of them on my Unix builds.
In any case, there should now be a python_d.exe file in your E:\Python\PCbuild folder. This is your Python executable.
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:

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

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.
