1、安装 Microsoft Visual C++ 14.0 选择 Windows 8.1 SDK 功能
2、复制 C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\include\stdint.h
3、粘贴 C:\Program Files (x86)\Windows Kits\10\Include\10.0.10240.0\ucrt
4、修改 C:\Program Files (x86)\Windows Kits\10\Include\10.0.10240.0\ucrt\inttypes.h
#include
#include "stdint.h"
5、卸载 Micrsoft Visual C++ 14.0
