Modify the Python installation directory under the lib\distutils\msvc9compiler.py file (if necessary msvccompiler.py the file will also need to make corresponding changes, depending on the system), find Get_build_ The version method directly return 9.0
Then find the Find_vcvarsall method to return the path of the Vcvarsall.bat directly (whichever is the path after the installation of your own machine)
return R ' C:\Users\Administrator\AppData\Local\Programs\Common\Microsoft\Visual C + + for Python\9.0\vcvarsall.bat ' Both changes are loaded with the substring string, and you can

To create the setup.py file, enter the following:
#!/usr/bin/env python
From Distutils.core import Setup, Extension
MOD = ' Extest '
Setup (Name=mod, Ext_modules=[extension (MOD, sources=[' extest.c ')])

Then enter the Python setup.py build in the corresponding prompt of Visual C + + for Python to build the C and Python version of the library file or python setup.py install

Of course, you can also create a Windows binary package
Python setup.py bdist_wininst
