This question already has an answer here:
这个问题在这里已有答案：
- “ImportError: No module named urls” while following Django Tutorial 3 answers
- 按照Django Tutorial 3的说法，“ImportError：没有名为urls的模块”
I am working through the DjangoProject tutorial with the polls app. As the tutorial states in part 4 I am trying to import 'reverse': from django.urls import reverse but getting the error:
我正在使用民意调查应用程序完成DjangoProject教程。正如教程在第4部分中所述，我试图导入'reverse'：从django.urls导入反向但得到错误：
from django.urls import reverse ImportError: No module named urls
来自django.urls import reverse ImportError：没有名为urls的模块
I have changed the ROOT_URLCONF to just 'urls', however, it did not work either.
我已经将ROOT_URLCONF更改为'urls'，但是，它也没有用。
Any help is appreciated, Thank you.
感谢任何帮助，谢谢。
