错误一：No module named 'MySQLdb'

原因：python3连接MySQL不能再使用mysqldb，取而代之的是pymysql。

解决方法：在python的MySQL包中，即路径：C:\Users\adong\AppData\Local\Programs\Python\Python36\Lib\site-packages\Django-2.0.3-py3.6.egg\django\db\backends\mysql

下的__init__.py文件中加入：

import pymysql

pymysql.install_as_MySQLdb()

错误二：django.core.exceptions.ImproperlyConfigured: mysqlclient 1.3.3 or newer is required; you have 0.7.11.None

原因：在解决了错误一以后出现了此错误。

解决方法：在python的MySQL包中，即路径：C:\Users\adong\AppData\Local\Programs\Python\Python36\Lib\site-packages\Django-2.0.3-py3.6.egg\django\db\backends\mysql

下的 base.py 文件中，注释掉一下两行代码：

if version < (1, 3, 3):

raise ImproperlyConfigured("mysqlclient 1.3.3 or newer is required; you have %s" % Database.__version__)

已解决： 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
