### 1.问题： ###

最近在学Django时遇到了一个问题，python3.6版本下使用pip安装mysql-python失败。其实一句话很简单，python3以上使用的是pymysql，如果是python2.7对应的是下mysql-python。那如何让Django驱动mysql数据库

当输入pip install mysql-python时报以下错误：

pip install mysql-python

错误信息如下

Traceback (most recent call last):
      File "D:\python\Python36\lib\site-packages\django\db\backends\mysql\base.py", line 26, in <module>
        import MySQLdb as Database
    ModuleNotFoundError: No module named 'MySQLdb'
    
    During handling of the above exception, another exception occurred:

    Did you install mysqlclient or MySQL-python?

原因：python3以上并不支持，python3以上使用pymysql，python2.7对应mysql-python。

#### 2.解决python3.6+Django+MySQL： ####

Django中的使用方法，在项目有wsgi.py 和 setting.py目录里的init.py下加如下代码：

import pymysql
    pymysql.install_as_MySQLdb()

然后就可以在命令行下输入创建应用的命令了。

python manage.py startapp XXX
