包括URLconf的simplesocial。url '似乎没有任何模式。…圆形进口

无法找到上述错误的来源:我已经审查了下面的链接，提供的解决方案没有解决我的问题:Django -循环模型导入问题 以下url似乎会导致出现循环导入错误。当注释掉时，错误不会出现。 simplesocial / urls . py

urlpatterns = [
    url(r"^$", views.HomePage.as_view(), name="home"),
    url(r"^test/$", views.TestPage.as_view(), name="test"),
    url(r"^thanks/$", views.ThanksPage.as_view(), name="thanks"),
    url(r"^admin/", admin.site.urls),
    url(r"^accounts/", include("accounts.urls", namespace="accounts")), #causes circular 
    reference
    url(r"^accounts/", include("django.contrib.auth.urls")), # causes circular reference
    url(r"^posts/", include("posts.urls", namespace="posts")), # causes circular reference
    url(r"^groups/",include("groups.urls",namespace="groups")),

账户/ urls . py

from django.conf.urls import url
from django.contrib.auth import views as auth_views
from . import views

app_name = 'accounts'


urlpatterns = [
    url(r"^$", views.LoginView.as_view(), name="login"), #works, review
    #url(r"^login/$",accounts.views.LoginView,name="login"),#additional url pattern. test.
    #url(r"^$", views.LoginView.as_view(template_name="accounts/login.html"), name="login"),#test. does this work??
    url(r"login/$", auth_views.LoginView.as_view(template_name="accounts/login.html")),
    url(r"logout/$", auth_views.LogoutView.as_view(), name="logout"),
    url(r"signup/$", views.SignUp.as_view(), name="signup"),

]

组/ urls . py

from django.conf.urls import url

from . import views

app_name = 'groups'

urlpatterns = [
    url(r"^$", views.ListGroups.as_view(), name="all"),
    url(r"^new/$", views.CreateGroup.as_view(), name="create"),
    url(r"^posts/in/(?P<slug>[-\w]+)/$",views.SingleGroup.as_view(),name="single"),
    url(r"join/(?P<slug>[-\w]+)/$",views.JoinGroup.as_view(),name="join"),
    url(r"leave/(?P<slug>[-\w]+)/$",views.LeaveGroup.as_view(),name="leave"),

]

职位/ urls . py

from django.conf.urls import url

from . import views

app_name='posts'

urlpatterns = [
    url(r"^$", views.PostList.as_view(), name="all"),
    url(r"new/$", views.CreatePost.as_view(), name="create"),
    url(r"by/(?P<username>[-\w]+)/$",views.UserPosts.as_view(),name="for_user"),
    url(r"by/(?P<username>[-\w]+)/(?P<pk>\d+)/$",views.PostDetail.as_view(),name="single"),
    url(r"delete/(?P<pk>\d+)/$",views.DeletePost.as_view(),name="delete"),

]

但是，在注释simplesocial/url .py文件中的以下3行代码时。 返回以下错误: NoReverseMatch在/ “accounts”不是注册的名称空间

urlpatterns = [
    url(r"^$", views.HomePage.as_view(), name="home"),
    url(r"^test/$", views.TestPage.as_view(), name="test"),
    url(r"^thanks/$", views.ThanksPage.as_view(), name="thanks"),
    url(r"^admin/", admin.site.urls),
    url(r"^accounts/", include("accounts.urls", namespace="accounts")), #1
    reference
    url(r"^accounts/", include("django.contrib.auth.urls")), # 2
    url(r"^posts/", include("posts.urls", namespace="posts")), # 3
    url(r"^groups/",include("groups.urls",namespace="groups")),
