在Django框架中使用python运行服务器的错误

Question

我是一名编程初学者，我的第一个项目是创建一个网站使用python与django框架作为后端。但试图运行服务器。我收到以下错误。那么有人可以解释一下吗？

(myvenv) C:\Users\Rohan Jain\venvi>python manage.py runserver 
    Performing system checks...

Answer 1

from django.conf.urls import include, url 
          ^^^^^^^ 
urlpatterns = [ 
# ... snip ... 
url(r'^community/', include('django_website.aggregator.urls')), 
url(r'^contact/', include('django_website.contact.urls')), 
# ... snip ... 
] 

所以，对于小的解释：

当您尝试运行您的程序，问题是，“包括”没有任何地方所定义的词。为了解决这个问题，你需要定义这个单词，因为这是来自django.conf.urls的一个函数，就像从你的文件开始导入它一样简单。

希望它能帮助，这里是一个有点文档，可以帮助您了解更多的关于Django的
