b2bchain区块链学习技术社区本文介绍了Django:从django.urls导入反向； ImportError:没有名为urls的模块 – python程序员分享，有助于帮助完成毕业设计以及求职，是一篇很好的资料。
对技术面试,学习经验等有一些体会，在此分享。
我正在使用民意调查应用程序完成DjangoProject教程。如本教程第4部分所述，我正在尝试导入“reverse”:from django.urls import reverse但出现错误:
从django.urls导入反向
ImportError:没有名为urls的模块
我已将ROOT_URLCONF更改为仅“urls”，但是，它也不起作用。
任何帮助表示赞赏，谢谢。
