尝试用ansib启动一个不稳定的实例时，获取“msg:找不到所需的可执行文件easy_install”

Question

一个人。一个任务。使用Ansible配置一台流浪者机器，以用作Python开发环境。

我曾试图给一台流浪机器配备安塞布尔。

我根据下面列出的说明为它设置了目录结构： https://danielgroves.net/notebook/2014/05/development-environments/

一切进展顺利，正如“流浪者起来”的最初部分所示：

$vagrant up

最终，目标是为流浪者的GAE工作设立机构，负责自动供应。（这可能是个好主意，也可能不是个好主意。）

我怎样才能保证在我的流浪箱上安装pip？

实际上，任何python配置都可以工作。

我已经阅读了文档或操作手册，并且很容易安装。

对于那些担心缺少库存文件的人，Vagrant自己创建了一个库存文件。Vagrantup.com有一个关于这个的页面，如果我得到了必要的声誉，我会发布这个页面。

我再仔细考虑一下这个问题，然后再修改它。
