【问题描述】：

一个人。一项任务。使用 Ansible 配置 Vagrant 机器以用作 Python 开发环境。

我尝试使用 Ansible 配置 Vagrant 机器。

我根据此处概述的说明为其设置了目录结构： https://danielgroves.net/notebook/2014/05/development-environments/

一切都很顺利，如“vagrant up”回复的开头部分所示：

最终，我们的目标是在 Vagrant 中为 GAE 工作做好准备，并使用 Ansible 进行自动配置。（这可能不是一个好主意。）

如何让 Ansible 在我的 Vagrant box 上安装 pip？

真的任何 python 配置都可以工作。

我已通读文档或剧本和 easy_install。

对于那些担心缺少库存文件的人，Vagrant 会自己创建一个。 Vagrantup.com 对此有一个页面，如果我获得必要的声誉，我将发布该页面。

在我考虑了更多之后，我将回顾这个问题并对其进行修改。

标签： python vagrant ansible

【解决方案1】：

它正在尝试使用easy_install name=pip 安装 pip。这已经过时了，不应再使用easy_install。

当前的方法是运行get-pip.py（参见installation instructions）。在 Ansible 中运行的命令是 python get-pip.py。

【讨论】：

感谢您的快速回复。在我给它打上绿色复选标记之前，我会尝试一下。
效果很好，谢谢。如果您与访问受限的用户一起运行，请运行 get-pip.py --user 并在 Ansible 中使用 pip: extra_args=--user 调用。
// .这也对我有用。我特别推荐在允许你运行任意 Python 脚本的系统上使用 get-pip.py，比如 Vagrant 运行的那些。
出于某种原因，ansible documentation 只字未提easy_install 已被弃用。
