无法识别 URL 模式中的错误

Question

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

如果我不在 leadmanager.urls 中包含 accounts.urls（来自帐户应用程序），一切正常，但是一旦我包含 accounts.urls，我就会收到以下错误（所有这些应用程序在 settings.py):

注册

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

    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（主要）：

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()),
]

frontend.urls:

from django.urls import path
from . import views

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

Answer 1

在 .api 中，我正在导入 serializers.py 但我有一个输入错误，我的文件被称为 serailizers.py，在修复文件名称后一切都开始工作了！

我只希望有某种方法可以检测到此语法错误，因为我收到的错误不是很有帮助。
