Answer 1

我认为您使用的是python2.x和django1.x，但是本教程是针对Django 2.x的，所以您需要更新到python3，并使用pip下载django2.1的最新版本，它可以正常工作。可能的原因可能是使用IDE下载Django和Python，因为有些IDE中的插件都是过时的版本。visualstudio和Intellij Idea插件是主要原因。我建议使用Django的集成命令工具编写VS代码。在

Answer 2

实际上，include存在于django.conf.urls

在网址.py用下面的代码代替from django.urls import include

from django.conf.urls import include

Answer 3

由于您使用的是Python2.7，而且django 2.0不支持Python2.7（请参见release notes），所以我认为您使用的是旧版本的django。在

在这种情况下，您可以在这里找到include函数django.conf.urls：

from django.conf.urls import include

从docs开始：

Changed in Django 2.0: In older versions, this function is located in django.conf.urls. The old location still works for backwards compatibility.

因此，如果您使用Django 2.0，则可以使用这两种方法导入include：

^{pr2}$

但对于以前的版本，只有第一个是正确的。在

至于path，它在Django 2.0中绝对是新的。在旧版本中，您应该使用^{}：

from django.conf.urls import url
