1.安装报错信息：
error: Microsoft Visual C++ 9.0 is required. Get it from http://aka.ms/vcpyt
hon27
或者fatal error C1083: Cannot open include file: 'config-win.h':
No such file or directory
error: command 'C:\Users\cao.wenhao\AppData\Local\Programs\Common\Mic
rosoft\Visual C++ for Python\9.0\VC\Bin\cl.exe' failed with exit status 2
2.不要直接使用pip install python-ldap django-auth-ldap，pip install会安装最新版本
3.到官网寻找低版本下载：https://pypi.python.org/pypi/django-auth-ldap/1.1.4
https://pypi.python.org/pypi/python-ldap/2.4.13
4.下载完成安装即可
