python - "ImportError: No module named urls"遵循 Django 教程

Question

我正在关注官方 django 教程 https://docs.djangoproject.com/en/1.10/intro/tutorial04/

我正在使用 Django 1.9.8，现在在 /polls/views.py 中出现以下错误:

File "C:\Users\hk\Documents\mysite\polls\views.py", line 4, in <module>
    from django.urls import reverse
ImportError: No module named urls

polls/views.py

from django.shortcuts import get_object_or_404, render
from django.http import HttpResponseRedirect, HttpResponse
from django.urls import reverse

from .models import Choice, Question
# ...

mysite/urls.py

from django.conf.urls import include, url
from django.contrib import admin

admin.autodiscover()

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

mysite/mysite/urls.py

from django.conf.urls import include,url
from django.contrib import admin

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

该教程需要 Django 1.10，而您似乎使用的是旧版本。在这种情况下，您应该按如下方式导入 reverse:

from django.core.urlresolvers import reverse

要升级您的 Django 版本，请使用以下命令(在您的命令行中，不是在 Python shell 中):

pip install --upgrade django
