Did you install mysqlclient or MySQL-python?

问题:

　　版本兼容性问题

解决:

　　方法一:  安装pymysql, 在setting.py的同级目录__init__.py中添加:

　　　　import pymysql

　　　　pymsql.install_as_MySQLdb()

　　方法二: 安装mysqlclient, 但是不能直接安装, 只能使用:

　　　　pip install https://download.lfd.uci.edu/pythonlibs/h2ufg7oq/mysqlclient-1.3.13-cp36-cp36m-win_amd64.whl

　　　　如果为32位系统python2.7请修改为: mysqlclient-1.3.13-cp27-cp27m-win_amd32.whl即可, 其他同理
