在Django教程的第3部分导致此错误的原因是什么？

I have run into an issue while working through the Django tutorial, specifically when adding more views to the poll application. For reference, this is the beginning of the section that trips me up: https://docs.djangoproject.com/en/1.5/intro/tutorial03/#writing-more-views

我在处理Django教程时遇到了一个问题,特别是在为poll应用程序添加更多视图时。作为参考,这是让我兴奋的部分的开头:https://docs.djangoproject.com/en/1.5/intro/tutorial03/#writing-more-views

Prior to that section, I can get the polls/ view to show up with no issue. But when I add three additional views to make polls/views.py look like this:

在该部分之前,我可以让民意调查/视图显示没有问题。但是当我添加三个额外的视图来使polls / views.py看起来像这样:

def detail(request, poll_id):
    return HttpResponse("You're looking at poll %s." % poll_id)

def results(request, poll_id):
    return HttpResponse("You're looking at the results of poll %s." % poll_id)

def vote(request, poll_id):
    return HttpResponse("You're voting on poll %s." % poll_id)

and then make polls/urls.py look like this:

然后使polls / urls.py看起来像这样:

from django.conf.urls import patterns, url

from polls import views

urlpatterns = patterns('',
    # ex: /polls/
    url(r'^$', views.index, name='index'),
    # ex: /polls/5/
    url(r'^(?P<poll_id>\d+)/$', views.detail, name='detail'),
    # ex: /polls/5/results/
    url(r'^(?P<poll_id>\d+)/results/$', views.results, name='results'),
    # ex: /polls/5/vote/
    url(r'^(?P<poll_id>\d+)/vote/$', views.vote, name='vote'),
)

I get an error. As an aside, my mysite ROOT_URLCONF is pointing to mysite/urls.py which looks like this:

我收到一个错误。顺便说一下,我的mysite ROOT_URLCONF指向mysite / urls.py,如下所示:

from django.conf.urls import patterns, include, url

from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    url(r'^polls/', include('polls.urls')),
    url(r'^admin/', include(admin.site.urls)),
)

The error that I am getting is:

Looks like Python cannot import polls.urls - that's why __import__(name) fails. The "name" here would be your module name, 'polls.urls'.

看起来Python无法导入polls.urls - 这就是__import __(name)失败的原因。这里的“名称”将是您的模块名称'polls.urls'。

To find out why the system cannot import your polls.urls, try importing it interactively.

要找出系统无法导入polls.urls的原因,请尝试以交互方式导入它。

$ python manage.py shell

 Python ... blah blah
 ...

> import polls.urls

This will fail, but the traceback will give you the next clue to where your error is.

这将失败,但回溯将为您提供错误所在位置的下一个线索。

Good luck!
