Question

可能重复：
no such file to load — readline

我刚刚创建了一个rails应用程序，并试图进入控制台，但我一直收到错误

rellon@relloneee:~/Dropbox/Apress$ rails c
/home/rellon/.rvm/rubies/ruby-1.9.2-p290/lib/ruby/1.9.1/irb/completion.rb:9:in `require': no such file to load -- readline (LoadError)

    from script/rails:6:in `require'
    from script/rails:6:in `<main>'

我可以请一些帮助.....

我也试过撬，现在我收到了这条消息

Answer 1

看起来这符合你的问题

no such file to load -- readline

基本上，您可能缺少readline模块。
