我正在使用 python 3.8，启动服务器时出现错误：
Page not found (404)
Request Method: GET

admin/
The empty path didn't match any of these.
You're seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page.
我的民意调查/urls.py：
from django.urls import path
from . import views
urlpatterns = [
path('', views.index, name='index'),
] …
