python - 尝试使用 ansible 启动 Vagrant 实例时获取 "msg: Failed to find required executable easy_install"

Question

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

我曾尝试为 Vagrant 机器配置 Ansible。

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

一切顺利，如对“vagrant up”的响应的初始部分所示:

最终，目标是在 Vagrant 中设置 GAE 工作，并使用 Ansible 进行自动配置。 (这可能是也可能不是一个好主意。)

如何让 Ansible 在我的 Vagrant 盒子上安装 pip？

实际上任何 python 配置都可以工作。

我已通读文档或剧本以及 easy_install。

对于那些担心缺少库存文件的人，Vagrant 自己创建了一个。 Vagrantup.com 有一个关于此的页面，如果我获得必要的声誉，我会发布该页面。

我会重新审视这个问题，并在我进一步考虑之后进行修改。

Answer 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)。然后在 Ansible 中运行的命令是 python get-pip.py。
