使用Ansible，如何在系统范围内安装PythonBrew?

问题描述

我正在尝试使用Ansible(v 1.3.3)创建一个剧本，以按照 Pythonbrew自述文件.

I'm trying to create a playbook with Ansible (v 1.3.3) to install Pythonbrew system-wide on a Debian server following the instructions in the Pythonbrew readme file.

我能够安装Pythonbrew，但无法安装所需的特定版本的Python.我怀疑该问题与Ansible所运行的外壳环境有关.

I am able to get Pythonbrew installed but I cannot install the specific version of Python that I want with it. I suspect the issue has to do with the shell environment Ansible is running under.

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

When I run this playbook, it fails with the following output

在过去一个小时左右的时间内，我一直在进行调整，但都无济于事.有人对此有任何建议吗?

I've been tweaking things for the last hour or so to no avail. Does anybody have any suggestions for fixing this?

推荐答案

通过 PythonBrew安装脚本，我能够弄清楚这一点. (并且正好赶上弃用PythonBrew ！)

By peeking at the PythonBrew install script, I was able to figure this out. (And just in time for the deprecation of PythonBrew!)

这是无需手动干预即可安装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.

Here's the playbook that installs PythonBrew without manual intervention. This may be of interest to anyone trying to script PythonBrew to install automatically.

    # This step allows install to continue without new shell. Pulled from:

    - 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
