修改python安装目录下Lib\distutils\msvc9compiler.py文件(如有必要可能msvccompiler.py文件也需要做相应更改，视系统而定)，找到get_build_version方法直接return 9.0
然后再找到find_vcvarsall方法直接返回vcvarsall.bat的路径（以自己机器安装后的路径为准）
return r‘C:\Users\Administrator\AppData\Local\Programs\Common\Microsoft\Visual C++ for Python\9.0\vcvarsall.bat‘ 两个改变都加载文档子字符串后就可以

创建setup.py文件 输入内容如下:
#!/usr/bin/env python 
from distutils.core import setup, Extension
MOD = ‘Extest‘
setup(name=MOD, ext_modules=[Extension(MOD, sources=[‘Extest.c‘])])

然后在Visual C++ for Python 相应的prompt中输入python setup.py build 就可以构建c和python版的库文件了或python setup.py install

当然也可以建立一个windows的二进制包
python setup.py bdist_wininst
