python - Django runserver 报错，全新安装，Django 初次使用者

Question

所以我决定学习 Django，如果我不能让它工作，这将是一个挑战。

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

(base) runout@runout:~$ python -m django --version2.2.1

我正在学习 djangoproject.com 上的初学者教程

第一行代码是创建一个网站，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。我在网上到处寻找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？

Answer 1

显然缺少 python 包。你可以像这样安装它:

pip 安装 sqlparse
