Question

我刚刚创建了一个Django项目并尝试使用虚拟环境。我已成功安装：

 django 1.9.11.
 virtual environment
 python 3.4.4. 
 pymysql

我以为我做的一切都正常，但是我无法运行django开发服务器，它在文件中给了我很多错误：

base.py
__init__.py
connections.py
err.py

在我尝试运行服务器后，它给了我这个权利：

python manage.py runserver
Performing system checks...

Unhandled exception in thread started by <function check_errors. <locals>.wrapper at 
Traceback (most recent call last):

我如何解决这个问题，以便我可以使用mysql运行开发服务器？谢谢。

The above exception was the direct cause of the following exception:
