后台创建管理员 createsuperuser 时 报django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module. Did you install mysqlclient?

pip install pymysql 

结果版本0.9.3

django.core.exceptions.ImproperlyConfigured: mysqlclient 1.3.13 or newer is required; you have 0.9.3.

需要pip指定版本号安装

结果清华源没有这个版本，换阿里云

pip install -i https://mirrors.aliyun.com/pypi/simple/ pymysql==1.3.13

阿里也没有，只能国外了

pip install jupyter -i http://pypi.tuna.tsinghua.edu.cn/simple --trusted-host pypi.tuna.tsinghua.edu.cn
