尝试运行服务器时pymysql和Django出现很多错误

Question

我刚创建了一个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 

我想我做的一切权利，但我不能够运行Django开发服务器，它给了我很多的错误中的文件：

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

它给我这个权利后，我试着运行服务器：

python manage.py runserver 
Performing system checks... 

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

我将如何解决这个问题，所以我可以运行与MySQL开发服务器？ 谢谢。

Answer 1

我从来没有找到答案，但只是删除了这个项目和我的环境包含django和python。现在我可以创建没有这些错误的项目。
