Python 3.6 32bit在Win下安装pycrypto的方法(VS 2017)

在测试一个python操作AES加密解密的脚本时，发现需要安装一些依赖package，大部分直接pip install就搞定了，结果到pycrypto的时候，却遇到了pip报错安装失败的问题，仔细看了下发现是编译出错，搜索了下找到了这个：https://github.com/dlitz/pycrypto/issues/218，原来是需要VS Build Tools环境的问题，按照最后的提示（指定32位编译环境）：

for Python 3.6 32 bit following set of commands worked:

cd “C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Auxiliary\Build”
vcvarsall.bat x86_amd64
cd \
set CL=-FI”%VCINSTALLDIR%\tools\msvc\14.14.26428\include\stdint.h”
pip install pycrypto

执行后，提示：

winrand.c
src/winrand.c: fatal error C1083: Cannot open include file: ‘D:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\\tools\msvc\14.14.26428\include\stdint.h’: No such file or directory

stdint.h没找到，进自己这边的tools\msvc路径一看，原来是版本号略有不同，修改为本地正确的路径：

D:\>set CL=-FI”%VCINSTALLDIR%\tools\msvc\14.13.26128\include\stdint.h”

然后再次pip install…就ok了：

D:\>pip install pycrypto
