* 安装pymysql模块

pip install pymysql

## pymysql repalce mysqldb
import pymysql
pymysql.install_as_MySQLdb()

* mysqlclient 版本太低 

 报错：

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：

cd {python_root_dir}/Lib\site-packages\django\db\backends\mysql

base.py

# 找到base.py文件，注释掉 base.py 中如下部分（35/36行）

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

* 编码问题

报错：

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

解决：

cd {python_root_dir}/Lib\site-packages\django\db\backends\mysql

operations.py

#找到operations.py文件（146行），将decode改为encode
#linux vim 查找快捷键：？decode

if query is not None:
    query = query.decode(errors=‘replace‘)
return query

#改为
if query is not None:
    query = query.encode(errors=‘replace‘)
return query
