django报错 django.core.exceptions.ImproperlyConfigured: mysqlclient 1.4.0 or newer is required； you have 0.10.1

django 3.1,Python3.8.2  启动项目报错如下：

django.core.exceptions.ImproperlyConfigured: mysqlclient 1.4.0 or newer is required; you have 0.10.1.

解决

项目的__init__文件加如下内容：

import pymysql
pymysql.version_info = (1, 4, 0, "final", 0)
pymysql.install_as_MySQLdb()
