无法识别 URL 模式中的错误

如何解决无法识别 URL 模式中的错误

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

如果我不在leadmanager.urls 中包含accounts.urls（来自accounts 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:
Traceback (most recent call last):

    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')),include('leads.urls')),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),]

解决方法

在 .api 中，我导入了 serializers.py，但我输入错误，我的文件名为 serailizers.py，在修复文件名后一切都开始工作了！

我只是希望有某种方法可以检测这种语法错误，因为我收到的错误不是很有帮助。
