DistutilsPlatformError in mingw built Python 2 (msys2)

Trying to do many things using setuptools in a mingw built Python 2 (For example msys2’s mingw-w64-x86_64-python2 fails with this exception:

$ python setup.py build_ext
Traceback (most recent call last):
  File "setup.py", line 1, in <module>
    from setuptools import setup, Extension
  File "mingw64/lib/python2.7/site-packages/setuptools/__init__.py", line 160, in <module>
    monkey.patch_all()
  File "mingw64/lib/python2.7/site-packages/setuptools/monkey.py", line 104, in patch_all

    __import__(name)

    from distutils.msvc9compiler import Reg
  File "mingw64/lib/python2.7/distutils/msvc9compiler.py", line 306, in <module>
    raise DistutilsPlatformError("VC %0.1f is not supported by this module" % VERSION)
distutils.errors.DistutilsPlatformError: VC 6.0 is not supported by this module

distutils.msvc9compiler doesn’t like being imported on mingw built Python, and this hack isn’t necessary there.

P.S. I’m going to send a PR.

@krzychb A quick workaround would be to allow the function to continue, even without the ‘required’ compiler.

In your case, in the file C:/msys32/mingw32/lib/python2.7/distutils/msvc9compiler.py remark line 306, and add the pass statement, so that the code looks more or less like the following:

+---[C:/msys32/mingw32/lib/python2.7/distutils/msvc9compiler.py:309]
| 
| # More globals
| VERSION = get_build_version()
| if VERSION < 8.0:
|     pass
| #    raise DistutilsPlatformError("VC %0.1f is not supported by this module" % VERSION)
| # MACROS = MacroExpander(VERSION)
| 
+---

This probably should do the trick…

Somehow, over a year later, this is still an issue. In my case not related to setuptools though - I used python3-pip from mingw64 to install bcrypt. Same error, same remedy. Thank you @PeterMosmans.
