无法导入名称包括[关闭]

Question

我正在遵循 django 中的教程并获得以下错误。

找到了一些解决方案，但没有解决我的错误。教程链接是this。

我得到的错误附在下面。在复制问题之前，请帮我解决这个问题。我正在学习 python 和 django 服务，所以对我有很大帮助。

编辑 1：我将附上两者的 urls.py，以便帮助识别

在 polls/urls.py 中

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

from . import views

urlpatterns = [
  url(r'^$', views.index, name='index'),
]

和 mysite/urls.py

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

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

Answer 1

我已经找到了上述问题的解决方案。 django的版本是主要原因。更新 django 版本清除了之前引发的错误。

更新前的版本是1.3，现在是1.10

要更新django版本，

$ sudo pip install -U Django

Answer 2

你必须在pollsurls中包含include

from django.conf.urls import include
