Rails控制台不起作用

Question

我在我的Opensuse上安装了ruby 2.0.0和rails 4.0.0但是rails控制台不起作用。 我有这个错误消息：

/home/zellou_i/.rubies/ruby-2.0.0-p247/lib64/ruby/2.0.0/irb/completion.rb:9:in `require': cannot load such file -- readline (LoadError)
    from /home/zellou_i/.rubies/ruby-2.0.0-p247/lib64/ruby/2.0.0/irb/completion.rb:9:in `<top (required)>'
    from /home/zellou_i/.gem/ruby/2.0.0/gems/railties-4.0.0/lib/rails/commands/console.rb:3:in `require'
    from /home/zellou_i/.gem/ruby/2.0.0/gems/railties-4.0.0/lib/rails/commands/console.rb:3:in `<top (required)>'
    from /home/zellou_i/.gem/ruby/2.0.0/gems/railties-4.0.0/lib/rails/commands.rb:53:in `require'
    from /home/zellou_i/.gem/ruby/2.0.0/gems/railties-4.0.0/lib/rails/commands.rb:53:in `<top (required)>'
    from bin/rails:4:in `require'
    from bin/rails:4:in `<main>'

我不明白，我安装了readline但他无法加载它。

Ruby需要使用readline支持进行编译。 确保安装libreadline6及其dev头文件（特定于debian的软件包，适应suse），然后重新编译你的ruby。
