ruby /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in`require'：无法加载这样的文件 - libnotify（LoadError）

Question

我是红宝石更新鲜，我想使用这个pomo util：https://github.com/visionmedia/pomo#readme。

但是当我在我的ubuntu 12.10终端上执行pomo时：

/var/lib/gems/1.9.1/gems/commander-4.1.3/lib/commander/runner.rb:365:in 
  `block in require_program': 
   program version required (Commander::Runner::CommandError)
    from /var/lib/gems/1.9.1/gems/commander-4.1.3/lib/commander/runner.rb:364:in `each'
    from /var/lib/gems/1.9.1/gems/commander-4.1.3/lib/commander/runner.rb:364:in `require_program'
    from /var/lib/gems/1.9.1/gems/commander-4.1.3/lib/commander/runner.rb:52:in `run!'
    from /var/lib/gems/1.9.1/gems/commander-4.1.3/lib/commander/delegates.rb:11:in `run!'
    from /var/lib/gems/1.9.1/gems/commander-4.1.3/lib/commander/import.rb:10:in `block in <top (required)>'
    /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require': 
      cannot load such file -- libnotify (LoadError)
    from /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
    from /var/lib/gems/1.9.1/gems/pomo-2.0.2/lib/pomo.rb:5:in `<top (required)>'
    from /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
    from /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
    from /var/lib/gems/1.9.1/gems/pomo-2.0.2/bin/pomo:7:in `<top (required)>'
    from /usr/local/bin/pomo:23:in `load'
    from /usr/local/bin/pomo:23:in `<main>'

我该怎么办。谢谢你！

Answer 1

不完全确定问题是什么。但至少从修复此错误开始：

cannot load such file -- libnotify

...与：

sudo apt-get install libnotify1
sudo gem install libnotify

祝你好运，它将解决问题。

就我而言，这是一个RVM Ruby版本问题。我使用的是Ruby 1.9，当我将其更改为1.8时，迁移工作正常。

rvm use 1.8
