众所周知，很多Python的库都需要编译（大概率是用了Cython），这时直接用pip安装会报错：error: Microsoft Visual C++ 14.0 is required.

不知为何，我的电脑死活不能安装上VC，只能用mingw作为编译器。

1. 编辑你的Python路径/Lib/distutils/distutils.cfg

   [build]
   compiler=mingw32
   [build_ext]
   compiler = mingw32
   // To solve the gcc error of "error: enumerator value for '__pyx_check_sizeof_voidp' is not an integer constant"
   // if you install a mingw for 64bit thendefine = MS_WIN64

仍然会报错 Unknown MS Compiler version XXXX

2. 编辑你的Python路径/Lib/distutils/cygwinccompiler.py
   在

   elif msc_ver == '1600':

    # VS2010 / MSVC 10.0
    return ['msvcr100']
   

后添加

elif msc_ver == '1927' or msc_ver=='1929':
    # MinGW64 with gcc 8.3.0  兼容 gcc version 8.1.0 (x86_64-win32-seh-rev0, Built by MinGW-W64 project)
    return ['msvcr120'] # seem to be a dynamic-linker program name for command `ld`

其中1927改为你的Compiler version
