我使用Ruby on Rails的4.0.5，我有这在我的.bash_profile：导轨安装突然找不到
-s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*
但我发现了这个错误：
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>
的Rails工作正常，但突然它不再工作了。我如何让Rails再次工作？
供参考，在这里是运行rvm info的输出：
