Python django：包含的URLconf'；DB#u query.url'；看起来里面没有任何图案

我是django的新手，在运行manage.py脚本时遇到问题。我的项目叫做DB_query。 这就是我要做的：我运行./manage.py makemigrations 这是我得到的错误：

 /home/ec2-user/atlas_web/atlas_web/local/lib/python2.7/site-       packages/pkg_resources/__init__.py:1222: UserWarning: /home/ec2-user/.python-eggs is writable by group/others and vulnerable to attack when used with get_resource_filename. Consider a more secure location (set with .set_extraction_path or the PYTHON_EGG_CACHE environment variable).
  warnings.warn(msg, UserWarning)

我在url文件中写错了什么？

谢谢

这是主URL.py还是包含在应用程序中？如果是，请显示主URL。正如错误末尾所述，“如果在文件中看到有效的模式，则问题可能是由循环导入引起的。”因此，您需要检查视图导入Daniel，这是main url.py。罗德里格斯，我如何检查我的进口不是循环的？
