python3.8 + django3.0.7 使用pymysql报错：django.core.exceptions.ImproperlyConfigured: mysqlclient 1.3.13 or newer is required; you have 0.9.2

1.python3.8 + django3.0.7 使用pymysql报错：

django.core.exceptions.ImproperlyConfigured: mysqlclient 1.3.13 or newer is required; you have 0.9.2

2.报错原因：是django2.2以上版本内部的一个限制

3.解决方法：修改django内部源码

4.修改文件：C:\Users\chenjianwen\AppData\Local\Programs\Python\Python38\Lib\site-packages\django\db\backends\mysql\base.py,注释掉两行即可

#if version < (1, 3, 13):
#    raise ImproperlyConfigured('mysqlclient 1.3.13 or newer is required; you have %s.' % Database.__version__)

 5.修改后保存运行正常
