Django教程1

Question

我开始学习Django，现在我正在创建我的第一个应用，我按照教程中的每一步（https://docs.djangoproject.com/en/1.9/intro/tutorial01/），但它不起作用，它让我失望执行python manage.py runserver时出现以下错误行：

Unhandled exception in thread started by <function wrapper at 0x7ffdfa76d8c0>

Traceback (most recent call last):

NameError: name 'include' is not defined

您忘记在mysite/urls.py中导入包含。

from django.conf.urls import include, url
