如何安裝「的ReadLine」鋼軌控制檯

Question

確定我試圖運行「軌道控制檯」的命令，但這裏就是我得到：

/home/user/.rvm/rubies/ruby-1.8.7-p352/lib/ruby/1.8/irb/completion.rb:10:in `require': no such file to load -- readline (LoadError) 
    from /home/user/.rvm/rubies/ruby-1.8.7-p352/lib/ruby/1.8/irb/completion.rb:10 
    from /home/user/.rvm/gems/ruby-1.8.7-p352/gems/railties-3.1.0/lib/rails/commands/console.rb:3:in `require' 
    from /home/user/.rvm/gems/ruby-1.8.7-p352/gems/railties-3.1.0/lib/rails/commands/console.rb:3 
    from /home/user/.rvm/gems/ruby-1.8.7-p352/gems/railties-3.1.0/lib/rails/commands.rb:37:in `require' 
    from /home/user/.rvm/gems/ruby-1.8.7-p352/gems/railties-3.1.0/lib/rails/commands.rb:37 
    from script/rails:6:in `require' 
    from script/rails:6

我知道這太晚了。

沒有這樣的文件加載 - 的ReadLine（LoadError）

嘗試加入gem ’rb-readline’到您的Gemfile）
