我必须开始学习 django，但我在启动 localhost 时遇到了问题。我得到的错误是：-

ModuleNotFoundError: No module named 'pages.app'

我的代码中的错误是下面显示的包含语句

from django.contrib import admin
from django.urls import path


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

如果您知道解决方案，请帮助....

【问题讨论】：

您必须在INSTALLED_APPS中包含页面应用程序

标签： python django web-applications

【解决方案1】：

只需将您的应用程序包含在Settings.py 文件的INSTALLED_APPS 列表中即可。您的服务器没有获取您的应用程序并导致问题。

INSTALLED_APPS = [
'pages'
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
]

【讨论】：

我已经提到了上面的代码，但它是说 path('', include('pages.urls')), NameError: name 'include' is not defined in my code from django.contrib import admin from django.urls import path urlpatterns = [ path('admin/', admin.site.urls), path('', include('pages.urls')), ]
@EmranulHaque 您是否从 django.urls 导入了“include”？例如：从 django.urls 导入路径，包括
哎呀，我想我忘了添加 include.. 非常感谢，现在它正在工作

【解决方案2】：

您需要在 settings.py 文件的“INSTALLED_APPS”中添加您的应用。

INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'pages']

【讨论】：

我已经提到了上面的代码，但是在我的代码from django.contrib import admin from django.urls import path urlpatterns = [ path('admin/', admin.site.urls), path('', include('pages.urls')), ]中是说path('', include('pages.urls')), NameError: name 'include' is not defined
在那个文件中导入这个from django.conf.urls import include
