python - 在 django 基本应用程序中运行服务器时出现问题

Question

我必须开始学习 django，并且在启动本地主机时遇到问题。 我得到的错误是:-

C:\Users\acer\Desktop\Example>py manage.py runserver
Unhandled exception in thread started by <function check_errors.<locals>.wrapper at 0x0637DC90>
Traceback (most recent call last):
  File "C:\Users\acer\AppData\Local\Programs\Python\Python37-32\lib\site-packages\django\utils\autoreload.py", line 225, in wrapper
    fn(*args, **kwargs)

  File "<frozen importlib._bootstrap>", line 983, in _find_and_load
  File "<frozen importlib._bootstrap>", line 965, in _find_and_load_unlocked
ModuleNotFoundError: No module named 'pages.app'

我的代码中的错误是下面所示的 include 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，请帮忙......

只需将您的应用包含在 Settings.py 文件的 INSTALLED_APPS 列表中即可。您的服务器未获取您的应用并导致问题。

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