Ansible：gem 列表中缺少罗盘核心

Question

我遇到了 grunt 构建的问题，所以我检查了指南针的版本 (compass -v)，结果出现了同样的消息：

stderr: /usr/lib/ruby/1.9.1/rubygems/dependency.rb:247:in `to_specs': Could not find compass-core (~> 1.0.2) amongst [compass-1.0.3, sass-3.4.18] (Gem::LoadError)
    from /usr/lib/ruby/1.9.1/rubygems/specification.rb:777:in `block in activate_dependencies'
    from /usr/lib/ruby/1.9.1/rubygems/specification.rb:766:in `each'
    from /usr/lib/ruby/1.9.1/rubygems/specification.rb:766:in `activate_dependencies'
    from /usr/lib/ruby/1.9.1/rubygems/specification.rb:750:in `activate'
    from /usr/lib/ruby/1.9.1/rubygems.rb:1232:in `gem'
    from /usr/local/bin/compass:22:in `<main>'

我已经为我的服务器提供了 ansible，并且我已经检查过 sass :

Sass 3.4.18 (Selective Steve)

有人知道如何调试吗？

编辑

事实上，我使用的是旧方法来安装 sass 和指南针。卸载并重播ansible任务后，我看到只有root安装了gem。

$ gem list

*** LOCAL GEMS ***


$ sudo gem list

*** LOCAL GEMS ***

chunky_png (1.3.4)
compass (1.0.3)
compass-core (1.0.3)
compass-import-once (1.0.5)
ffi (1.9.10)
multi_json (1.11.2)
rb-fsevent (0.9.5)
rb-inotify (0.9.5)
sass (3.4.18)

所以我的问题变了：How to install gem for a specific user or for all the user with ansible ?

这是我的 ansible 脚本：

  - name: Install ruby gems as Grunt dependencies
    gem: name="{{ item }}" state=present include_dependencies=yes user_install=yes
    with_items:
      - sass
      - compass

include_depencies 和 user_install 是可选标志

Answer 1

要为特定用户安装 gem，您需要在用户上下文中运行它，例如

  - name: Install ruby gems as Grunt dependencies
    gem: name="{{ item }}" state=present include_dependencies=yes user_install=yes
    with_items:
      - sass
      - compass
    become: yes
    become_user: someuser

要全局安装它，请将 user_install 设置为假值：

  - name: Install ruby gems as Grunt dependencies
    gem: name="{{ item }}" state=present include_dependencies=yes user_install=no
    with_items:
      - sass
      - compass
    become: yes
    become_user: root
