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

if version < (1, 3, 13):         
         

raise ImproperlyConfigured(‘mysqlclient 1.3.13 or newer is required; you have %s.’ % Database.version)  

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

File “C:Python37libsite-packagesdjangodbackendsmysqloperations.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
