Ошибка установки Locomotive CMS при выполнении пакета

Я пытаюсь установить LocomotiveCMS и стараюсь следовать этому руководству: http://doc.locomotivecms.com/guides/get-started/install-engine. Я подхожу к той части, где я должен войти:

bundle exec rails g locomotive:install

Который затем просто выводит команду использования рельсов:

MacBook-Pro:myapp chris$ bundle exec rails g locomotive:install
Usage:
  rails new APP_PATH [options]

Options:
  -r, [--ruby=PATH]              # Path to the Ruby binary of your choice
                                 # Default: /Users/chris/.rvm/rubies/ruby-2.0.0-p195/bin/ruby
  -b, [--builder=BUILDER]        # Path to a application builder (can be a filesystem path or URL)
  -m, [--template=TEMPLATE]      # Path to an application template (can be a filesystem path or URL)
      [--skip-gemfile]           # Don't create a Gemfile
      [--skip-bundle]            # Don't run bundle install
  -G, [--skip-git]               # Skip Git ignores and keeps
  -O, [--skip-active-record]     # Skip Active Record files
  -S, [--skip-sprockets]         # Skip Sprockets files
  -d, [--database=DATABASE]      # Preconfigure for selected database (options: mysql/oracle/postgresql/sqlite3/frontbase/ibm_db/sqlserver/jdbcmysql/jdbcsqlite3/jdbcpostgresql/jdbc)
                                 # Default: sqlite3
  -j, [--javascript=JAVASCRIPT]  # Preconfigure for selected JavaScript library
                                 # Default: jquery
  -J, [--skip-javascript]        # Skip JavaScript files
      [--dev]                    # Setup the application with Gemfile pointing to your Rails checkout
      [--edge]                   # Setup the application with Gemfile pointing to Rails repository
  -T, [--skip-test-unit]         # Skip Test::Unit files

....

Я не уверен, что я сделал неправильно. Я следовал за гидом к письму...

Любая помощь приветствуется. Спасибо!

РЕДАКТИРОВАТЬ: «установка пакета», похоже, работала нормально.

Your bundle is complete!
Use `bundle show [gemname]` to see where a bundled gem is installed.

Моя версия рельсов:
