Django mysql连接错误

1.报错内容：

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

原因：django2.2和pymysql版本不匹配。mysqldb不支持python3解决方案：

两个错误会同时出现

1、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、AttributeError: ‘str’ object has no attribute ‘decode’ 　　　

File “C:\Python37\lib\site-packages\django\db\backends\mysql\operations.py”, line 146, in last_executed_query 　　
query = query.decode(errors=‘replace’) 　
解决办法：
打开此文件把146行的decode修改为encode
