Did anybody manage to install pypotrace or is able to install mingwin it's like mission impossible for me I've passed the last 12 hours trying to found out how but nothing is working and description are poor please could any body help? This is where you can get it:
pypotrace web site
This problem was so much of a pain that I ported potrace to python directly rather than using hooks and requiring local compile.
pip install potracer
https://github.com/tatarize/potrace
I implemented the same API as pypotrace so it should be fairly painless.
Since you are working in windows you need the following steps:
You may need the python distutils package - pip install -U distuilts should do the job.
You will also need Cython - the windows installers are here.
You need to install mingw and make sure it is working in
msys mode - run msys and you should get a command prompt in it type
gcc --version and make sure you get a sensible reply.
also make sure your python runs from within msys
Do the required downloads:
potrace source,
agg source site broken or the GitHub zip file here,
potrace source from here and unzip it.
The follow the instructions at the link you gave and tell us where they stop working.

Over the last few days of headaches, I've found 3 possible methods to do this, all of which have issues.
PyGObject's pip install fails due to a lack of Cairo and probably other dependencies. While this would be my preferred method, it would probably be the hardest to fulfill.
Using MSYS2 allows me to use GObject through the mingw64 python, but using pip to get my other modulues such as pylint fails. I'd like to have an MSYS2 or similar install on my system anyways to make some windows binaries, so I'm very open to this as well.
EDIT: Got pip to work in MSYS2. Make sure to sync toolchain with pacman.
PyGObject for Windows seems messy at best and isn't up-to-date. Would require having a second python installation anyways, giving no benefit over MSYS2.
Note I'm a complete newbie to Unix and have little experience with CLI's in general, so any help regarding MSYS2 will need to be explained as if to a child. My only other experience with this stuff involved an endless cycle of hell that was installing Arch to a separate partition, breaking said install, then reinstalling again.
I also tried Cygwin, but I couldn't get that to run Python with GObject at all with my "install all the needed packages then pray" method. Creating a Gtk.Window() caused the terminal to use none of the memory it had and explode.
MSYS2 is currently the only "officially" supported way: https://pygobject.readthedocs.io/en/latest/getting_started.html#windows
pip in MSYS2 should work in general, if something doesn't please file a bug at https://github.com/Alexpux/MINGW-packages/issues .
As you said in the third alternative to install a new Python version, you can create and run multiple Python versions using pyenv. You can go through the installation section of their Github repo for installation and an overview: https://github.com/pyenv/pyenv/
For a comprehensive guide on how to use it, you read this amazing post by Real Python:
https://realpython.com/intro-to-pyenv/
A little background: I am working on some python modules that other developers on our team will use. A common theme of each module is that one or more messages will be published to Kafka. We intend at this time to use the Confluent Kafka client. We are pretty new to python development in our organization -- we have traditionally been a .NET shop.
The complication: while the code that we create will run on Linux (rhel 7), most of the developers will do their work on Windows.
So we need the librdkafka C library compiled on each developer machine (which has dependencies of its own, one of which is OpenSSL). Then a pip install of confluent-kafka should just work, which means a pip install of our package will work. Theoretically.
To start I did the install on my Linux laptop (Arch). I knew I already had OpenSSL and the other zip lib dependencies available, so this process was painless:
git clone librdkafka repo
configure, make and install per the README
pip install confluent-kafka
done
The install of librdkafka went into /usr/local:
/usr/local/lib/librdkafka.a
/usr/local/lib/librdkafka++.a
/usr/local/lib/librdkafka.so -> librdkafka.so.l
/usr/local/lib/librdkafka++.so -> librdkafka++.so.l
/usr/local/lib/librdkafka.so.l
/usr/local/lib/librdkafka++.so.l
/usr/local/lib/pkgconfig/rdkafka.pc
/usr/local/lib/pkgconfig/rdkafka++.pc
/usr/local/include/librdkafka/rdkafkacpp.h
/usr/local/include/librdkafka/rdkafka.h
Now the painful part, making it work on Windows:
install precompiled OpenSSL
git clone librdkafka repo
open in VS2015
install libz via NuGet
build solution
install to where???
This is where I'm stuck. What would a standard install on a Windows 7/8/10 machine look like?
I have the following from the build output, but no idea what should go where in order to make the pip install confluent-kafka "just work":
/librdkafka/win32/Release/librdkafka.dll
/librdkafka/win32/Release/librdkafka.exp
/librdkafka/win32/Release/librdkafka.lib
/librdkafka/win32/Release/librdkafkacpp.dll
/librdkafka/win32/Release/librdkafkacpp.exp
/librdkafka/win32/Release/librdkafkacpp.lib
/librdkafka/win32/Release/zlib.dll
<and the .h files back in the src>
Any recommendations on an install location?
I'm not sure where the ideal place to install on Windows would be, but I ran the following test with some success.
I copied my output and headers to C:\test\lib and C:\test\include, then ran a pip install with the following options:
pip install --global-option=build_ext --global-option="-LC:\test\lib" --global-option="-IC:\test\include" confluent-kafka
Unfortunately, this doesn't quite work because the confluent-kafka setup does not support Windows at this time: https://github.com/confluentinc/confluent-kafka-python/issues/52#issuecomment-252098462
It's an old question but seems still no easy answer yet. Also Confluent seems too busy to work on Windows supporting...
I had the same headache couple weeks ago and after some research, I managed to make it work for me on Windows. I logged my finding and uploaded a pre-compiled library to my Git, please check and see if it helps. :D
https://github.com/MichaelZhangCA/confluent-kafka-python
My environment is Python 3.6 64 bit version but ideally, it should also work for 32 bit if you follow the same approach.
I assume you have successfully followed instructions from MichaelZhangCA (https://github.com/MichaelZhangCA/confluent-kafka-python/) from previous post.
If you did so, these probably were the last two commands executed:
::Install confluent-kafka
cd C:\confluent-kafka-python\confluent-kafka-python-0.11.4
python setup.py install
If that is correct, those DLLs were created under C:\confluent-kafka-python\librdkafka-reference\release\.
All you have to do is to copy them to a diretory already in Widnows' PATH.
For example, I use Anaconda 5.2 For Windows, with python 3.6. My Anaconda Prompt has an empty directory in PATH, so I copied there those DLL's:
::Anaconda Prompt - copy DLLs to a directory already in PATH
mkdir %CONDA_PREFIX%\Library\usr\bin
copy C:\confluent-kafka-python\librdkafka-reference\release %CONDA_PREFIX%\Library\usr\bin
If you don't use Anaconda, just copy those DLL's to any other directory in Windows' PATH. You may also leave them in C:\confluent-kafka-python\librdkafka-reference\release, and add this directory to PATH.
and thanks to anyone who gives some of their time to consider my problem.
What I need help on is for someone to give me a simple and accessible explanation on how to install that module. I have never, ever used anything from PyPi before, I have only heard of pip after looking up PyCallGraph.
I'm not a programmer first, I'm doing an accounting internship and am using python to write scripts to help me speed up some processes, at the urging of a colleague who himself uses python. I write scripts using Notepad++ and execute them through IDLE.
I'm currently working on optimizing a script I wrote and came upon PyCallGraph while checking this very site on tips on how to do so.
I tried the very minimalistic instruction of just doing "pip install pycallgraph" just about anywhere I could think of, including cmd.exe, to no avail. Runing get-pip.py directly seems to have worked for installing pip, though.
Otherwise I can always just stick with the cProfile printout and write-off using modules needing such an install, although that saddly seems to be quite a few...
Step 1: Install PIP
Open terminal (cmd.exe, PowerShell, whatever)
Download get-pip.py and place it in the working directory of your terminal
Install PIP by invoking python get-pip.py
Confirm that PIP was installed correctly by invoking command pip (should display help if success)
If pip didn't work, make sure your PATH environment variable has been set up correctly. In typical Windows installations pip is installed under c:\Python27\Scripts. Make sure this folder is included in PATH.
Step 2: Install your library with PIP
Invoke pip install pycallgraph
PIP installs the library and it can be now used from Python
I have tried using the jython setup.py install on my computer and its not working.
And how to install ez_setup.py on jython or is there another way to setup django on jython
Thank you in advance.
This tutorial shows you how to install it. Ideally everything boils down to two points:
First you need to get pip, here is a good tutorial on how that is done. If you don't want to read that, you can simply download pip from here. After that, you will need to extract it, I suggest 7-zip. After that, you can go into the directory and find setup.py. Run setup.py like jython setup.py install -> this might be different.
After that, you can do something like pip install django, and it should work if jython is your own python interpreter. Otherwise, you are going to have to go into your jython directory, then go into a directory called scripts. Then run pip.exe install django if you're running on windows.
Please note, that my advice is from that of a Windows user, so your experience might be different, and probably a lot more pleasant.
I'm working with PyInstaller under Python 2.6, which is only partially supported due to the mess MS have created with their manifest nonense which now affects Python since it is now MSVC8 compiled.
The problem is that the manifest embedding support relies on the pywin32 extensions in order to build which is a pain because without including the host's site-packages folder when I create the virtualenv (kinda defeats the point in a build environment) I cannot find a way to install the required extensions so they are accessible to PyInstaller.
Has anyone found a solution to this issue?
I found http://old.nabble.com/Windows:-virtualenv-and-pywin32--td27658201.html (now a dead link) which offered the following solution:
Browse http://sourceforge.net/projects/pywin32/files/ for the URL of the exe you want
Activate your virtualenv
Run easy_install http://PATH.TO/EXE/DOWNLOAD
This works with modern versions of setuptools (circa February 2014, reported by tovmeod in the comments).
If you are using an old version of setuptools (or distribute it merged back into setuptools), you may get this error message:
error: c:\users\blah\appdata\local\temp\easy_install-ibkzv7\pywin32-214.win32-py2.6.exe is not a valid distutils Windows .exe
In which case:
Download the exe yourself
Activate your virtualenv
Run easy_install DOWNLOADED_FILE.exe
I rather hopefully tried "pip install" rather than "easy_install", but this didn't work, and likely never will (citation needed).
Finally, I found but haven't tested a solution at http://www.mail-archive.com/python-list#python.org/msg272040.html which is:
Solved this by copying the pywin32.pth file into my virtualenv site-packages
and editing the file to point to the path.
If the other options don't work for you, maybe this will?
For Python 2.7 or 3.x use pypiwin32.
pip install pypiwin32
OK, well since I had to find a way forward I improvised. I've internally created a git repository with a hacked-together version of pywin32 that will install within a virtualenv using the standard setup.py script. It took a lot of fiddling to make it work right but I managed to get it to load and the dependent code now works as I need it to. If people feel this would be of benefit to the community please post a comment: if I get enough I'll try and put something up on my github account.
This may have been improved since previous answer, since I've successfully installed pywin32 on sandbox on several machines without any specific "hacks" :
$ virtualenv sandbox
$ sandbox\scripts\activate
(sandbox) $ git clone https://github.com/Travis-Sun/pywin32.git
(sandbox) $ cd pywin32
(sandbox) $ python setup.py install
Tested with following environment :
windows 7
git
python 2.7.10 with virtualenv
VS2008. It may also work (but I've not tested yet) with
http://www.microsoft.com/en-us/download/details.aspx?id=44266
Edit: Scratch this for now, appears to be some problems with the installation still...
I got rather tired of the whole situation, and just created a set of converted wheels ("wheel convert <.exe>"). I'll try and keep them maintained for the most recent build, but do shout if there are any issues.
https://tr00st.co.uk/python/wheel/pywin32/
Installation can be done easily using pip and pointing to the package matching your version and architecture. For example, for Python 3.5/amd64:
pip install https://tr00st.co.uk/python/wheel/pywin32/pywin32-219-cp35-none-win_amd64.whl
Caveat: The --upgrade process currently fails, as the uninstall procedure is unable to clean up after itself (Access Denied when cleaning up win32api.pyd) - this is only when removing the temporary directory, which can be manually deleted. Easiest way around this is to uninstall and reinstall instead of upgrading, then manually delete the temporary folder.
