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

使用python3.7+django2.2+pymysql时遇到这个错误,

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

别急,这主要是django2.2内部的一个版本限制在作怪

处理方案

1.修复源码
按照文中配置,报错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:
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、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

找到安装python的这个位置
django.core.exceptions.ImproperlyConfigured: mysqlclient 1.3.13 or newer is required; you have 0.9.2_第1张图片

改成如图
django.core.exceptions.ImproperlyConfigured: mysqlclient 1.3.13 or newer is required; you have 0.9.2_第2张图片django.core.exceptions.ImproperlyConfigured: mysqlclient 1.3.13 or newer is required; you have 0.9.2_第3张图片ps.django2.2不支持pyMySQL,但2.2是LTS,有想过试试mysqldb,但是MySQLDB又不支持python3。。。。的确让人头大。
