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
