Python 运行服务器后出现Django 404错误（'；找不到页面'；）

我的项目名为“pages”，当我运行服务器时，会出现此错误。任何人都知道如何修复此错误

找不到页面（404） 请求方法：获取请求URL:使用 在pages_project.URL中定义了URLconf，Django尝试了以下URL 模式，按以下顺序排列：admin/空路径与以下任何模式都不匹配 这些您看到此错误是因为您的 Django设置文件。将其更改为False，Django将显示 标准404页

My settings.py文件如下所示：

我的“页面”文件夹中的我的url.py是

from django.urls import path


from . import views


urlpatterns = [

    path(' ', views.HomePageView.as_view(), name='home'),

]

任何帮助都将不胜感激。谢谢。

错误告诉您，main url.py仅包含管理模式。您还需要包含页面URL

此外，路径模式中还有一个空格。移除它。

您的路径中有一个空间<代码>''。这意味着url是。删除空格

path('', views.HomePageView.as_view(), name='home')

---

您可以投影URL：删除空间

pages/url.py

在项目url中添加应用程序url，以便项目可以查看应用程序url

projectName/url.py

urlpatterns = [
    path(r'^$', views.HomePageView.as_view(), name='home'),
]

from django.conf.urls import include, url
from django.contrib import admin
from django.conf import settings
from django.views.static import serve

urlpatterns = [     
    ...  
    url(r'^', include('pages.urls')),      
]
