Ошибка консоли Rails 3.1

Я только что создал приложение для рельсов и пытался войти в консоль, но все время получаю сообщение об ошибке

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>'

Могу ли я получить некоторую помощь.....

Я также пробовал подглядывать, и теперь я получаю это сообщение
