Django 1.11 循环导入错误，还有 url 模式...当前路径不匹配

Question

我正在使用 Django 1.11。这是我的回溯：

'irbSite.urls' from 'C:\Users\doxpr\Desktop\WorkingProje
ctClassBased Views\WorkingProjectClassBased 
Views\capstoneProject\capstoneProject\irbSite\urls.py'>' does not appear 
to have any p
atterns in it. If you see valid patterns in the file then the issue is 
probably caused by a circular import.

如上所示，当我包含以下内容时出现循环导入错误：

url(r'irbSite/', include('irbSite.urls', namespace = 'irbSite')),
url(r'irbSite/', include('django.contrib.auth.urls'))

在urls.py项目文件夹中：

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

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^$', auth_views.LoginView.as_view(template_name = 
        'irbSite/login.html'),name='login'),
    url(r'irbSite/', include('irbSite.urls', namespace = 'irbSite')),
    url(r'irbSite/', include('django.contrib.auth.urls'))
]

然而，如果我不包含它，我的登录页面将会出现，但是当我点击注册时 link 我得到这个错误： "url patterns" ... "^admin/ ^$ [name='login'] 当前路径 register.html 与其中任何一个都不匹配。"

我的目录（不是代码）：

irbsite
  pycache
  migrations
  static
  templates
  init.py
  admin.py
  apps.py
  forms.py
  models.py
  tests.py
  urls.py
  views.py
project
  pycache
  init.py
  settings.py
  urls.py
  wsgi.py
manage.py

我的 views.py（在 irbSite 文件夹中）：

from django.contrib.auth import login, logout
from django.core.urlresolvers import reverse_lazy
from django.views.generic import CreateView
from . import forms

class Registration(CreateView):
    form_class = forms.UserCreateForm
    success_url = reverse_lazy('login')
    template_name = 'register.html'

我的 urls.py（在 irbSite 文件夹中）：

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

app_name = 'irbSite'

ulrpatterns = [
    url(r'logout/$', auth_views.LogoutView.as_view(),name='logout'),
    url(r'register/$',views.Registration.as_view(template_name = 
      'irbSite/register.html'),name='registration'),
]

我正在修改我从 udemy 课程中学习的教程。我碰壁了，有什么建议吗？

请注意，您没有收到循环导入错误，该消息只是表明可能是循环导入导致了问题。

在这种情况下，您的 irbSite/urls.py 有错字。应该是 urlpatterns 而不是 ulrpatterns.
