Django2.2 bug

1.python3.6报错：AttributeError: 'str' object has no attribute 'decode'

修改方法：把decode改成encode便可

2. django.core.exceptions.ImproperlyConfigured: mysqlclient 1.3.3 or newer is required; you have 0.7.11

找到Python安装路劲下的Python36-32\Lib\site-packages\django\db\backends\mysql\base.py文件

将文件中的以下代码注释

if version < (1, 3, 3):
    raise ImproperlyConfigured("mysqlclient 1.3.3 or newer is required; you have %s" % Database.__version__)

3.Dajango 数据库切换为MYSQL的问题：Error loading MySQLdb module.解决方案

$ pip install pymysql

安装完毕，打开( python目录 ：**\Python3.7.3\Lib\site-packages\django\db\backends\mysql)__init__.py,添加代码

import pymysql

pymysql.install_as_MySQLdb()
