How to use mingw32 when installing a distutils package?

Question

I've come across a github project which I am trying to install and run it but I've run into some problems. I've also put this up as an issue. The entire pip log is available there.

The problem appears to revolve around distutils, if I understand correctly:

f:\python27\Lib\distutils\dist.py:267: UserWarning: Unknown distribution option: 'use_2to3' warnings.warn(msg) error: Unable to find vcvarsall.bat

Looking this up I was directed to error: Unable to find vcvarsall.bat.

Now checking my system I have MS Visual C++ 2005,2008,2010 all installed.I don't have visual studio. I am using win 7 with git-bash which has MINGW32 installed. In the above thread fpessoa discusses setup.py install build --compiler=mingw32. I decided to try the following :

1. I had python 2.7 already installed.
2. Added mingw32's bin directory to environment variable: append PATH with f:\git\bin;

3. Created distutils.cfg located at C:\Python27\Lib\distutils\distutils.cfg to:

   [build]
   compiler=mingw32
   

Unfortunately I'm still getting the same error.

Is this the same thing as executing setup.py install build --compiler=mingw32 ? If not how do I get setup.py to use the --compiler=mingw32 argument when it reads requirement.txt?

The contents of my f:\git\bin are:

Answer 1

I found a solution on the web but havn't tested it: install MinGW . in the MinGW's bin dictionary find mingw32-make.exe, copy it and rename as make.exe other procedures are the same as in your question.

Answer 2

I had the same error; and solution explained in that post was not working.
My solution was to install cygwin and use its python as a default python for my windows.

Note: Default version of python on cygwin is 2.6

Answer 3

You appear to be using Python 2.7 for this project, but your error message:

UserWarning: Unknown distribution option: 'use_2to3' warnings.warn(msg) error: Unable to find vcvarsall.bat

refers to the 2to3 utility that converts Python 2.x to Python 3.x syntax.

http://docs.python.org/2/library/2to3.html

Are you sure you are using all Python 2.7 libraries that appropriate for your operating system?

Answer 4

I was eventually able to find an answer using https://zignar.net/2012/06/17/install-python-on-windows/.

Thanks for your help. As it turns out I now understand that GIT-BASH does not contain a compiler which is what ming32w has within it.
