Question

我正在使用Ruby on Rails 4.0.5，我在.bash_profile中有这个：

 -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*

但是我收到了这个错误：

The program 'rails' can be found in the following packages:
 * ruby-railties-3.2
 * ruby-railties-4.0
Try: sudo apt-get install <selected package>

Rails工作正常，但突然它不再工作了。我怎样才能让Rails再次运行？

供参考，以下是运行rvm info：

的输出
