我是直接下载课程提供的完整源码想运行下看看效果，前面这几步都做了

1. 先安装mysql
   安装的时候需要密码设置为root
2. 通过navicat 新建数据库 库名为mxonline
3. navicat 导入sql文件
4. pip install -r requirements.txt 安装依赖包
5. http://www.lfd.uci.edu/~gohlke/pythonlibs/#mysql-python
   下载 MySQL_python-1.2.5-cp27-none-win_amd64.whl
   然后pip install MySQL_python-1.2.5-cp27-none-win_amd64.whl 安装mysqldb驱动

然后在虚拟环境下运行 python manage.py runserver 时出错
报错信息如下

(testvir) C:\Users\hello\Desktop\code\MxOnlie>python manage.py runserver
Traceback (most recent call last):
  File "manage.py", line 11, in <module>

安装的包如下

(testvir) C:\Users\hello\Desktop\code\MxOnlie>pip list

在非虚拟环境下也出错，但报错信息有区别：

就像把代码跑起来，要怎么解决呀。
