我正在尝试使用 Ansible (v 1.3.3) 创建一个剧本，以便按照Pythonbrew 自述文件中的说明在 Debian 服务器上安装 Pythonbrew 系统范围。

我能够安装 Pythonbrew，但我无法安装我想要的特定版本的 Python。我怀疑这个问题与运行 Ansible 的 shell 环境有关。

这是我的剧本脚本：

- name: Install and configure PythonBrew
  hosts: dev
  user: root
  vars_files:
    - vars.yml
  gather_facts: false

  tasks:
    - name: Install PythonBrew Debian packages
      apt: pkg=${item} state=installed update-cache=yes
      with_items: ${pythonbrew_packages}

    - name: Install PythonBrew system-wide
      shell: curl -kL http://xrl.us/pythonbrewinstall | bash creates=/usr/local/pythonbrew executable=/bin/bash

    - name: Update bashrc for PythonBrew
      lineinfile:
        dest=~/.bashrc
        regexp='^'
        line='[[ -s $HOME/.pythonbrew/etc/bashrc ]] && source $HOME/.pythonbrew/etc/bashrc'
        state=present
        create=True

    - name: Install python binary
      shell: pythonbrew install -v ${python_version} executable=/bin/bash

当我运行此剧本时，它失败并显示以下输出

失败：[devserver] => {“更改”：true，“cmd”：“pythonbrew install -v 2.7.3”，“delta”：“0：00：00.016639”，“end”：“2013-10-11 15：21：40.989677”，“rc”：127，“开始”：“2013-10-11 15：21：40.973038”}标准错误：/bin/bash：pythonbrew：找不到命令

在过去的一个小时左右，我一直在调整东西，但无济于事。有人对解决此问题有任何建议吗？

通过查看PythonBrew 安装脚本，我能够弄清楚这一点。（正好赶上 PythonBrew 的弃用！）

这是无需人工干预即可安装 PythonBrew 的剧本。任何尝试编写 PythonBrew 脚本以自动安装的人都可能对此感兴趣。

变量.yml

#
# Python/PythonBrew Settings
# TODO: replace old-style Ansible ${vars} with jinja-style {{ vars }}

project_name: MY_PROJECT

python:
  version: 2.7.3

pythonbrew:
  root: /usr/local/pythonbrew
  bashrc_path: $HOME/.pythonbrew/etc/bashrc

  packages:
    - curl
    - zlib1g-dev
    - libsqlite3-dev
    - libssl-dev
    - libxml2
    - libxml2-dev
    - libxslt1-dev

pythonbrew.yml

    - name: Install python binary
      shell: export PYTHONBREW_ROOT=${pythonbrew.root}; source ${pythonbrew.root}/etc/bashrc; pythonbrew install ${python.version}
        executable=/bin/bash

    - name: Switch to python version
      shell: export PYTHONBREW_ROOT=${pythonbrew.root}; source ${pythonbrew.root}/etc/bashrc; pythonbrew switch ${python.version}
        executable=/bin/bash
