Heroku: грабли прервана

Question

Я пытаюсь запустить БД: мигрировать на Heroku (приложение работает отлично локально), и я получаю эту ошибку:

Удалить группу активов , поскольку он больше не существует в Rails4.

Просто переместить драгоценные камни, включенные в него в глобальное пространство

# Gems used only for assets and not required 
# in production environments by default. 
group :assets do 
    gem 'sass-rails' 
    gem 'coffee-rails' 

    # See https://github.com/sstephenson/execjs#readme for more supported runtimes 
    # gem 'therubyracer', :platforms => :ruby 
    #gem 'therubyracer' 
    #gem 'less-rails' 
    #gem 'twitter-bootstrap-rails' 
    gem 'uglifier', '>= 1.0.3' 
end 

# becomes 

# group :assets do 
    gem 'sass-rails' 
    gem 'coffee-rails' 

    # See https://github.com/sstephenson/execjs#readme for more supported runtimes 
    # gem 'therubyracer', :platforms => :ruby 
    #gem 'therubyracer'
