I just installed everything needed for Ruby on Rails on my Ubuntu system. But, when I use the rails command, it outputs these errors:

How do I fix this?
解决方案
I would advice to install Ruby + Ruby Gems using a version manager, such as RVM, instead of the distro Ruby : http://ryanbigg.com/2010/12/ubuntu-ruby-rvm-rails-and-you/
