摇尾安装:未找到Wagtail命令

Question

我正在尝试安装摇尾。正如文档所建议的那样，我使用pip安装了wagtail：

tigran@tigran:~/projects/website$ pip install wagtail

但是，当我试图创建一个项目时，我会得到以下错误：

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

这里怎么了？

Answer 1

我想“煤气门”的评论是正确的。在virtualenv之外运行入门命令也会在Ubuntu16.04中为我带来这个问题。

您需要创建并激活一个虚拟环境，这样它才能工作。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

Answer 2

另一种方法是使用内置于Python3.6及更高版本的-m venv命令。

检查Python版本

python --version

创建venv并安装需求

python -m venv venv
source venv/bin/activate
pip install -r requirements.txt

安装完成后，尝试运行wagtail命令。
