Django连接mysql报错django.core.exceptions.ImproperlyConfigured: mysqlclient 1.3.13 or newer is required

解决办法：

    找到python安装目录下的base.py文件，目录参考：/home/用户名/.virtualenvs/项目名/lib/python3.5/site-packages/django/db/backends/mysql/base.py

注视掉这两行：

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

重新在项目manage.py路径下执行文件迁移命令：

    python manage.py makemigrations

    python manage.py migrate
