django错误该怎么办，因为我无法调试

Question

请帮帮我。我正在关注Django文档，一切正常，但这是一个导致错误的错误。如果我删除网址（r＆＃39; ^民意调查/＆＃39;，包含（＆＃39; polls.urls＆＃39;，名称空间=＆＃34;民意调查＆＃34;）），则不会出错后来它在创建表单时引起问题。那现在该怎么办......？

polls/urls.py
...
from django.conf.urls import url, include
from polls import views
from django.contrib import admin
urlpatterns = [
    url(r'^polls/', include('polls.urls', namespace="polls")),
    url(r'^admin/', include(admin.site.urls)),
    url(r'^$', views.index, name='index'),
    url(r'^specifies/(?P<question_id>[0-9]+)/$', views.detail, name='detail'),
    # ex: /polls/5/results/
    url(r'^(?P<question_id>[0-9]+)/results/$', views.results, name='results'),
    # ex: /polls/5/vote/
    url(r'^(?P<question_id>[0-9]+)/vote/$', views.vote, name='vote'),
]
