アセットをレールにプリコンパイルする際にエラーが発生しました。3. `rake aborted！予期しないトークン：キーワード（リターン） `

Question

私は資産をプリコンパイルしようとしている：

Gemfile：

source 'https://rubygems.org' 

gem 'rails', '~> 3.2.1' 

# Bundle edge Rails instead: 
# gem 'rails', :git => 'git://github.com/rails/rails.git' 


# Gems used only for assets and not required 
# in production environments by default. 
group :assets do 
    gem 'sass-rails', '~> 3.2.3' 
    gem 'coffee-rails', '~> 3.2.1' 
    gem 'uglifier',  '>= 1.0.3' 
    gem 'less' 
end 

gem 'jquery-rails' 


# To use ActiveModel has_secure_password 
# gem 'bcrypt-ruby', '~> 3.0.0' 

# To use Jbuilder templates for JSON 
# gem 'jbuilder' 

# Use unicorn as the web server 
# gem 'unicorn' 

# Deploy with Capistrano 
# gem 'capistrano' 

# To use debugger 
# gem 'ruby-debug19', :require => 'ruby-debug' 


# Bundle the extra gems: 
gem 'haml' 
gem 'devise' 
gem 'hpricot' 
gem 'ruby_parser' 
gem 'haml-rails' 
gem 'simple_form' 
gem 'paperclip', "~> 2.0" 
gem 'mini_magick' 
gem "geocoder", :require => "geocoder" 
gem 'kaminari' 
gem 'aws-s3' 
gem 'cancan' 
gem "friendly_id", "~> 4.0.1" 
gem 'thin' 
gem "twitter-bootstrap-rails" 

group :development do 
    gem 'sqlite3' 
    gem 'pry' 
    gem 'rails-pry' 
end 

group :production do 
    # gem 'mysql2' 
    # gem 'ruby-mysql', '~> 2.9.3' 
    gem 'exception_notification', :require => 'exception_notifier' 
    gem 'pg', '~> 0.11' 
end 

group :test do 
    # gem 'rspec' 
    # gem 'rspec-rails' 
    # gem 'cucumber' 
    # gem 'cucumber-rails' 
    # gem 'capybara' 
    # gem 'database_cleaner'

    # gem 'factory_girl' 
    # gem 'builder', '~> 2.1.2' 
    # gem 'launchy' 
    # gem "mocha" 
end 
# Bundle gems for the local environment. Make sure to 
# put test-only gems in this group so their generators 
# and rake tasks are available in development mode: 
# group :development, :test do 
# gem 'webrat' 
# end

あなたのpop_bottles/app/assets/javascripts/application.jsにエラーが発生しています。これはHerokuの問題ではありません。
