compass install bootstrap -> NoMethodError в строке [32] sass-rails-3.2.6/lib/sass/rails/helpers.rb: неопределенный метод `[]' для nil:NilClass

После запуска этой команды

compass install bootstrap

Я получаю это сообщение:

identical sass/styles.scss

...

identical javascripts/bootstrap-typeahead.js

 31     def resolver
 32       options[:custom][:resolver]
 33     end

Я попробовал обходной путь -> https://gist.github.com/castus/4044953

def resolver
  if ::Rails::env == "production"
    options[:custom][:resolver]
  else
    Resolver.new(CompassRails.context)
  end
end

и все равно не повезло :)

У меня есть это в моем config/compass.rb
