mariadb使用中出现的错误解决

1、版本错误

raise ImproperlyConfigured('mysqlclient 1.3.13 or newer is required; you have %s.' % Database.__version__)

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

　解决办法：C:\Python37\Lib\site-packages\django\db\backends\mysql（python安装目录）打开base.py，注释掉以下内容：

 　　　　　　　if version < (1, 3, 13):

　　　　　　　　　　raise ImproperlyConfigured('mysqlclient 1.3.13 or newer is required; you have %s.' % Database.__version__)

　2 编码错误

File "C:\Python37\lib\site-packages\django\db\backends\mysql\operations.py", line 146, in last_executed_query

　　  query = query.decode(errors='replace')

　　AttributeError: 'str' object has no attribute 'decode'

　　解决办法：打开此文件把146行的decode修改为encode
