但是当我尝试创建一个项目时，出现以下错误:

tigran@tigran:~/projects/website$ wagtail start website
wagtail: command not found

这里有什么问题吗？

我猜@gasman 的评论是正确的。在 virtualenv 之外运行入门命令确实会在 Ubuntu 16.04 中为我产生这个问题。

您需要创建并激活一个 virtualenv 才能工作。假设您已经安装了 virtualenv:

mkdir myproject && cd myproject
virtualenv yourvirtualenv -p /usr/bin/python3
source yourvirtualenv/bin/activate
pip install wagtail
wagtail start website
