Loading up first time server for Rails 3, and received this error

Started GET "/users/new" for 127.0.0.1 at 2010-07-11 23:07:03 -0400
Processing by UsersController#new as HTML
Completed   in 15ms

I18n::UnknownFileType (can not load translations from /Users/johnsmith/.rvm/gems/ruby-1.9.2-head/gems/activesupport-3.0.0.beta4/lib/active_support/locale/en.yml, the file type yml is not known):

I check out the file path to see what was there, and en.yml is there. Opened it up, and it all looks legit out of the box. I havn't moved anything anywhere. Not entirely sure why I'm getting this.

Here'开发者_开发问答s my gemfile :

source 'http://rubygems.org'

gem 'rails', '3.0.0.beta4'

gem 'sqlite3-ruby', :require => 'sqlite3'
gem "hpricot"
gem "ruby_parser"
gem "rack",          "1.1.0"
gem "rack-mount",    :git => "git://github.com/rails/rack-mount.git"
gem "rack-test",     "~> 0.5.0"
gem "erubis",        "~> 2.6.0"
gem "arel",          :git => "git://github.com/rails/arel.git"
gem "sqlite3-ruby"
#gem 'bj' #not entire sure what a bj is, but this version is wrong and kills the system
gem "rails3-generators", :group => :development 
gem 'nokogiri', '1.4.1'
gem 'aws-s3', :require => 'aws/s3'
gem 'authlogic'
gem 'i18n'

group :test do
  gem "test-unit",  "1.2.3"
  gem "rspec", :git => 'git://github.com/rspec/rspec.git'
  gem "rspec-rails", :git => 'git://github.com/rspec/rspec-rails.git'
  gem "factory_girl"
end


gem 'capistrano'

Also this is Ruby 1.9.3dev

Rails 3.0.0.beta4

Edit:

I added that i18n gem only after I received this error thinking that would resolve it, but its still the same error with or without it.

Went ahead and installed Ruby 1.8.7 and Rails 3.0.0.beta4 , and everything works perfectly.

Thanks Jed!
