R18n在Rails3中不起作用

Question

由于某种原因，我不能使用R18n虽然它已加载。有人可以给我一个暗示吗？

o0sel:~/rails_projects/demo> rails --version 
o0sel:~/rails_projects/demo> rails console
Loading development environment (Rails 3.0.5)
>> I18n.tr<tab><tab>
I18n.translate      I18n.translate!     I18n.transliterate  I18n.trust          I18n.try            
>> R18n.tr<tab><tab>
R18n.trust  R18n.try    
>> exit
o0sel:~/rails_projects/demo> ruby 
o0sel:~/rails_projects/demo> bundle install

我也遇到过r18n-desktop + actionmailer gems的问题，但是通过创建单独的gemset来克服它。它只包含action_mailer + dependencies，而不是整个rails stack。
