я только недавно обновил мое приложение railsжемчужины сgem update а такжеbundle update, Когда я попытался проверить это сrails s это дает мне эту ошибку:

/Users/Richard/.rvm/gems/ruby-1.9.2-p318/gems/railties-3.2.3/lib/rails/railtie/configuration.rb:85:inmethod_missing»: неопределенный методless' for # (NoMethodError)

Остальная часть сообщения об ошибке выглядит так:

Это ошибка с самоцветом Twitter Bootstrap? Я'я все еще учусь, так как бы мне это исправить? Любая помощь потрясающая.
