Python 关于mysql的django服务器运行错误

首先尝试django，当我执行“/manage.py runserver”时，它会显示：

  File "/Library/Python/2.7/site-packages/django/db/backends/mysql/base.py", line 27, in <module>
    raise ImproperlyConfigured("Error loading MySQLdb module: %s" % e)
django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module: dlopen(/Library/Python/2.7/site-packages/MySQL_python-1.2.4b4-py2.7-macosx-10.10-intel.egg/_mysql.so, 2): Library not loaded: /usr/local/opt/mysql/lib/libmysqlclient.18.dylib
  Referenced from: /Library/Python/2.7/site-packages/MySQL_python-1.2.4b4-py2.7-macosx-10.10-intel.egg/_mysql.so

File”/Library/Python/2.7/site packages/django/db/backends/mysql/base.py“，第27行，在
raise配置不正确（“加载MySQLdb模块时出错：%s”%e）
django.core.exceptions.impropertlyconfigured:加载MySQLdb模块时出错：dlopen（/Library/Python/2.7/site-packages/MySQL\u Python-1.2.4b4-py2.7-macosx-10.10-intel.egg//u MySQL.so，2）：未加载库：/usr/local/opt/MySQL/lib/libmysqlclient.18.dylib

我已经设置了mysql的默认数据库，并且安装了mysql Python dev。不知道发生了什么。有人来帮我…

你的数据库的settings.py中有什么？DATABASES={'default'：{'ENGINE'：'django.db.backends.mysql'，'NAME'：'books'，'USER'：'root'，'PASSWORD'：''，'HOST'：''，'PORT'：'3306'，}的可能重复项
