如何为rails控制台安装"readline"

Question

好吧,我正在尝试运行"rails console"命令,但这是我得到的:

/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

如何安装"readline"并使其正常工作？

Answer 1

我知道为时已晚.

没有这样的文件加载 - readline(LoadError)

尝试添加gem ’rb-readline’到您的Gemfile.)

Answer 2

rvm包已更改为rvm pkg

如果错误告诉我们这个会很好!啊!
