python - Django runserver错误，新安装，第一次使用Django

问题描述

所以我决定学习 Django，如果我不能让它发挥作用，这将是一个挑战。

在 Linux 上运行 Python 3.7.1（默认，2018 年 12 月 14 日，19:28:38）[GCC 7.3.0] :: Anaconda, Inc.

（基础）runout@runout:~$ python -m django --version 2.2.1

我正在学习djangoproject.com上的初学者教程

第一行代码是创建一个站点，我做了...

django-admin startproject mysite

第二行代码，是我遇到问题的地方。

python manage.py runserver

我的错误如下：

我对Django一无所知，我很高兴学习。我已经在网上寻找了解决这个问题的方法，但无济于事。任何人都可以让我启动并运行吗？

解决方案

显然缺少一个python包。你可以像这样安装它：

pip install sqlparse
