Question

我正在尝试使用Ansible（v 1.3.3）创建一个Playbook，按照Pythonbrew readme file中的说明在Debian服务器上安装Pythonbrew系统。

我能够安装Pythonbrew但是我无法安装我想要的特定版本的Python。我怀疑这个问题与shell环境有关.Ansible正在运行。

这是我的剧本剧本：

- 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，它会失败，并显示以下输出

失败：[devserver] =＆gt; {“已更改”：true，“cmd”：“pythonbrew 安装-v 2.7.3“，”delta“：”0：00：00.016639“，”结束“：”2013-10-11 15：21：40.989677“，”rc“：127，”start“：”2013-10-11 15：21：40.973038“} stderr：/ bin / bash：pythonbrew：找不到命令

我一直在调整最后一小时左右的事情但无济于事。有没有人有解决这个问题的建议？

通过偷看PythonBrew install script，我能够解决这个问题。（及时赶上deprecation of PythonBrew！）

这是在没有人工干预的情况下安装PythonBrew的剧本。任何试图编写PythonBrew脚本以自动安装的人都可能会对此感兴趣。

vars.yml

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

        line='[[ -s ${pythonbrew.bashrc_path} ]] && source ${pythonbrew.bashrc_path}'
        state=present
        create=True

    # This step allows install to continue without new shell. Pulled from:
    # https://github.com/utahta/pythonbrew/blob/master/pythonbrew/installer/pythonbrewinstaller.py#L91
    - 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

使用Ansible，如何在系统范围内安装PythonBrew？
