1. 下载相关的 Python for Windows Extensions 相关版本，并安装。

　　https://sourceforge.net/projects/pywin32/files/pywin32/Build%20214/

2.  设置 VS90COMNTOOLS 环境变量

1. Finding vcvarsx86_amd64.bat in C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\bin\x86_amd64 (depends on your setup)
2. Open a cmd prompt
3. Run SET VS90COMNTOOLS=%VS120COMNTOOLS% (depends on setup, seehttp://stackoverflow.com/a/10558328/2362877)
4. Run vcvarsx86_amd64.bat
5. Then pip install <package>
