модуль Bundler
Bundler обеспечивает согласованную среду для проектов Ruby, отслеживая и устанавливая точные драгоценности (gems) и версии, которые необходимы.
Bundler является частью стандартной библиотеки Ruby.
Bundler используется путем создания gemfiles, перечисляющих все зависимости проекта и (необязательно) их версии, а затем используя
require 'bundler/setup'
или Bundler.setup, чтобы настроить среду, в которой будут использоваться только указанные драгоценности (gems) и их указанные версии.
См. сайт Bundler для подробной документации по созданию gemfiles и Bundler.
Как стандартная библиотека внутри проекта, Bundler может использоваться для интроспекции загруженных и требуемых модулей.

end Включает запуск Bundler. После Bundler.setup вызова, все load или require gem'ов будут разрешены только если они указаны в Gemfile или стандартной библиотеке Ruby. Если в Gemfile указаны версии, будут загружены только эти версии.
Предполагая Gemfile
gem 'first_gem', '= 1.0' group :test do gem 'second_gem', '= 1.0' end
Код, использующий Bundler.setup, работает следующим образом:
require 'third_gem' # allowed, required from global gems require 'first_gem' # allowed, loads the last installed version Bundler.setup require 'fourth_gem' # fails with LoadError require 'second_gem' # loads exactly version 1.0
Bundler.setup может быть вызван только один раз, все последующие вызовы — это нет-опер.
Если список groups предоставлен, будут разрешены только gem'ы из указанных групп (gem'ы, не указанные в группах, относятся к специальной группе :default).
Чтобы загрузить все gem'ы из Gemfile (или только некоторые группы), см. Bundler.require.
