这个问题困扰了我很长时间。这几天，我先后安装了VC2019,VC2017,VC2015这些都安装过了，还是不行，愁死了。网上各种方法也都试过了，还是不行。今天突发奇想，竟然想到了办法。
我的系统是win10，装的是python3.7.2,现在安装的是VC2017，执行python setup.py build_ext --inplace时提示的错误为：
C:\python37\xn>python setup.py build_ext --inplace running build_ext building 'a' extension C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Tools\MSVC\14.16.27023\bin\HostX86\x86\cl.exe /c /nologo /Ox /W3 /GL /DNDEBUG /MD -IC:\python37\include -IC:\python37\include "-IC:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Tools\MSVC\14.16.27023\ATLMFC\include" "-IC:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Tools\MSVC\14.16.27023\include" /Tca.c /Fobuild\temp.win32-3.7\Release\a.obj a.c c:\python37\include\pyconfig.h(59): fatal error C1083: 无法打开包括文件: “io.h”: No such file or directory error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio\\2017\\Community\\VC\\Tools\\MSVC\\14.16.27023\\bin\\HostX86\\x86\\cl.exe' failed with exit status 2 |
所以，我从Windows Kits中把io.h复制到python的Incolude目录中就轻松解决了。
附：
Windows Kits中io.h所在的目录：C:\Program Files (x86)\Windows Kits\10\Include\10.0.17763.0\ucrt
python3.7.2的include目录：C:\python37\include
