我创建了一个Django网站，一切正常，直到在urls.py中添加新路径的那一刻：
应用的urls.py
from django.urls import path
from . import views
urlpatterns = [
path('', views.members_list, name='members_list_url'),
path('create/', views.MemberCreate.as_view(), name='member_create_url'),
path('<str:nickname>/', views.MemberPage.as_view(), name='member_page_url')
]
并出现错误消息：
(venv) D:\Documents\Desktop\percents_system\app\percentsystem>manage.py runserve

Exception in thread django-main-thread:

During handling of the above exception, another exception occurred:

raise ImproperlyConfigured(msg.format(name=self.urlconf_name))
django.core.exceptions.ImproperlyConfigured: The included URLconf 'percentsystem.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.
项目的urls.py
from django.contrib import admin
from django.urls import path, include, re_path
from .views import to_home
urlpatterns = [
path('admin/', admin.site.urls),
path('system/', include('system.urls')),
path('', to_home, name='home'),
]
我尝试将path('system/', include('system.urls'))更改为re_path('system/', include('system.urls')),
它没有帮助。
另外，如果要注释path('system/', include('system.urls')),字符串
from django.contrib import admin
from django.urls import path, include, re_path
from .views import to_home
urlpatterns = [
path('admin/', admin.site.urls),
#path('system/', include('system.urls')),
path('', to_home, name='home'),
]
然后服务器正常启动。 我不知道该怎么办，我已经尝试了2天来解决此问题。
此外，如果需要，还可以显示应用的views.py
from django.shortcuts import render
from django.shortcuts import redirect
from django.urls import reverse
from django.shortcuts import get_object_or_404

return render(request, 'system/base_system.html')
def members_list(request):
search_query = request.GET.get('search', '')
if search_query:
members = Member.objects.filter(Q(name__icontains=search_query) | Q(surname__icontains=search_query))
paginator = Paginator(members, 2)
page_number = request.GET.get('page', 1)
page = paginator.get_page(page_number)
is_paginated = page.has_other_pages()
is_searching = True
href = "?search={}&page=".format(search_query, page_number)
print(is_searching)
if page.has_previous():
prev_url = '?search={}&page={}'.format(search_query, page.previous_page_number())
else:

}
return render(request, 'system/members_list.html', context=context)
