python - 在/polls找不到页面

Question

我是“django”的初学者，所以我正在关注一些教程，而我正在看https://youtu.be/JT80XhYJdBw Clever Programmer的教程，他遵循django教程
一切都很不错，直到进行民意调查网址
views.py代码:

from django.shortcuts import render

from django.http import HttpResponse

def index(request):
    HttpResponse("Hello World.You're at the polls index")

民意测验\ urls.py的代码:

from django.urls import path

from . import views

urlpatterns = [
    path('', views.index, name='index'),
]

Mypr \ urls.py的代码:

from django.contrib import admin

from django.urls import path, include

urlpatterns = [
    path('admin/',admin.site.urls),
    path('polls/',include('polls.urls')),
]

我不明白，我做了同样的事情，但不仅是民意测验我也遇到了错误。

Page not found (404)
Request Method: GET
Request URL:    http://127.0.0.1:8000/polls/
Using the URLconf defined in Mypr.urls, Django tried these URL patterns, in 
this order:

admin/
The current path, polls/, didn't match any of these.

请我的前辈帮我。
注意:我使用的是django，windows的最新版本，并且作为编辑器，我使用的是Pycharm。
已经尝试过(并且不起作用):

from django.urls import path

from polls.views import index

urlpatterns = [
    path('', index, name='index'),
]

Answer 1

Page not found (404)
Request Method: GET
Request URL:    http://127.0.0.1:8000/polls/
Using the URLconf defined in Mypr.urls, Django tried these URL patterns, in this order:

admin/
The current path, polls/, didn't match any of these.

您看到此错误是因为Django设置文件中包含DEBUG = True。
将其更改为False，Django将显示一个标准的404页面。
