【问题描述】：

我在 django 项目 (leadmanager) leads, frontend, accounts 中有 3 个应用程序

如果我在leadmanager.urls 中不包含accounts.urls（来自accounts 应用程序），一切正常，但是一旦包含accounts.urls，我就会收到以下错误（所有这些应用程序都在settings.py 中注册）：

$ python manage.py runserver
Watching for file changes with StatReloader
Performing system checks...

Exception in thread django-main-thread:

    iter(patterns)
TypeError: 'module' object is not iterable

The above exception was the direct cause of the following exception:

django.core.exceptions.ImproperlyConfigured: The included URLconf 'leadmanager.urls' does not appear to have any patterns in 
it. If you see valid patterns in the file then the issue is probably caused by a circular import.

leadmanager.url（主）：

urlpatterns = [
    path('admin/', admin.site.urls),
    path('',include('frontend.urls')),
    path('',include('leads.urls')),
    path('',include('accounts.urls')),
]

lead.urls：

from rest_framework import routers
from .api import LeadViewSet

router = routers.DefaultRouter()
router.register('api/leads', LeadViewSet, 'leads')
app_name = 'leads'
urlpatterns = router.urls

accounts.urls：

from django.urls import path, include
from .api import ReigsterAPI
from knox import views as knox_views

app_name = 'accounts'
urlpatterns = [
  path('api/auth', include('knox.urls')),
  path('api/auth/register', RegisterAPI.as_view()),
]

前端.urls：

from django.urls import path
from . import views

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

【问题讨论】：

如果在您将 accounts.url 添加到基本 URL 时发生这种情况，您是否尝试过从 accounts.urls 中删除这两个路径？或者用简单的TemplateView 替换两者？
@FlipperPA 是的，如果只是将 path('auth/', TemplateView.as_view(template_name='index.html')) 放在 url 模式中，它就可以正常工作。
所以让我们找出是path('api/auth', include('knox.urls')), 还是path('api/auth/register', RegisterAPI.as_view()), 导致了问题 - 尝试单独注释掉每个问题，看看哪个会引发错误？如果是knox.urls，那么我们将不得不深入该应用程序的urls.py 以找到罪魁祸首。 :)
@FlipperPA 尝试过，但给出了同样的错误
@FlipperPA 搞定了！

【解决方案1】：

在 .api 中我是 import serializers.py 但我有一个输入错误，我的文件名为 serailizers.py，在修复文件名后一切都开始工作了！

我只是希望有办法检测到这个语法错误，因为我收到的错误不是很有帮助。
