Question

我对django和python都是全新的，目前我正在关注https://docs.djangoproject.com/en/2.0/intro/tutorial01/教程。

运行命令python manage.py runserver时出现以下错误。有人可以帮忙吗？

Performing system checks...

Answer 1

django.conf.urls

实际上存在包含

在 urls.py 中代替from django.urls import include写下代码

from django.conf.urls import include

Answer 2

由于您使用的是python 2.7，并且事实上django 2.0不支持python 2.7（请参阅release notes），我想您正在使用旧版本的Django。

在这种情况下，您可能会在include找到django.conf.urls函数：

from django.conf.urls import include

来自docs：

的Qoute

在Django 2.0中更改：在旧版本中，此函数位于django.conf.urls中。旧位置仍可用于向后兼容。

因此，如果您使用Django 2.0，则可以使用以下两种方法导入include：

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

但对于以前的版本，只有第一个是正确的。

至于path，它在Django 2.0中是全新的。在旧版本中，您应该使用url：

from django.conf.urls import url

Answer 3

我认为您使用的是Python 2.x和Django 1.x，但本教程适用于Django 2.x，因此您需要更新至Python 3并使用pip下载最新的Django 2.1，它可以正常工作。可能的原因可能是使用IDE下载Django和Python，因为某些IDE中的插件坚持使用过时的版本。 Visual Studio和Intellij Idea插件是主要原因。我建议将VS Code与Django的集成命令工具一起使用。
