django python 后端 解决：mysqlclient 1.4.3 or newer is required； you have 1.0.3.

花了两天的时间卡在这个地方真的是欲哭无泪啊！

小白一个，做django专题，跟着影片学学学，结果在

python3 manage.py makemigrations

卡到一个不行........

它总是会出现以下的报错：

PS C:\Users\User\PycharmProjects\mysite> python3 manage.py makemigrations

django.core.exceptions.ImproperlyConfigured: mysqlclient 1.4.3 or newer is required; you have 1.0.3.

但是明明我的mysqlclient版本是2.1.1，settings.py的DATABASES也没打错，so why??

后来我发现，只需要在__init__.py中加上

import pymysql

pymysql.version_info =(2, 1, 1, "final", 0)

pymysql.install_as_MySQLdb()

就可以了!!!!!!!!!!!!!!!!!

注意这个第二行的2,1,1是根据 mysqlclient的版本噢!!!!!!!

实在是太激动了，但不知道我理解的有没有错，如果有错再麻烦指正！
