I used this guide: [Rails Internationalization (I18n) API — Ruby on Rails Guides](http://guides.rubyonrails.org/i18n.html) to localize my  
sample application

i’ve set config/environment.rb, controllers/application.rb as it is  
written in the article

#views/home/index.html.erb

# \<%=t :hello\_world %\>

but when I start application the following error occurs:

ArgumentError in Home#index  
Showing app/views/home/index.html.erb where line #1 raised:

How to avoid this error?

I’m using Mongrel/Apache and my rails configuration is:

Ruby version 1.8.6 (i386-mswin32)  
RubyGems version 1.3.1  
Rails version 2.2.2  
Active Record version 2.2.2  
Action Pack version 2.2.2  
Active Resource version 2.2.2  
Action Mailer version 2.2.2  
Active Support version 2.2.2

Please, help me 🙂
