我刚刚开始学习django，我正在网上尝试一些教程。请帮忙。这只是一个接受用户输入的小型Web应用程序，并将其显示在留言板上。
我正在使用windows和django 1.11.7。我使用sublime文本编辑器进行python。
我不确定这个错误意味着什么。如果有人可以提供帮助，那将会有很大的帮助。这是我得到的错误：
` Unhandled exception in thread started by <function check_errors.<locals>.wrapper

这是显示错误的文件：
`# mb_project/urls.py
from django.conf.urls import include, url
from django.contrib import admin
urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'^', include('message_app.urls')),
]`
这是message_app / urls文件：
from django.conf.urls import url
from .views import Home_page_view
urlpatterns = [
url(r'^$', Home_page_view.as_view()),
]
谢谢
