Amber rebuild error

[just1602]

When I run amber rebuild I got this error:

/usr/local/lib64/ruby/gems/2.1.0/gems/i18n-0.7.0/lib/i18n.rb:284:in `enforce_available_locales!': :en is not a valid locale (I18n::InvalidLocale)

I run ruby 2.1.5 and amber 0.3.3.

This should be resolved with amber 0.3.4. try sudo gem update amber
