Cómo utilizar el paquete (0.9.1.pre1) con Rails y CouchRest

Question

Quiero usar la versión actual de empaquetador (Ha habido bastantes cambios de 0.8 a 0.9) para administrar las gemas de mi aplicación Rails.Primero creé un Gemfile en la raíz de la carpeta de la aplicación y le agregué todas las gemas necesarias.Luego coloqué (como se recomienda en el manual) el siguiente código en mi config/environment.rb:

begin
  # Require the preresolved locked set of gems.
  require File.expand_path('../.bundle/environment', __FILE__)
rescue LoadError
  # Fallback on doing the resolve at runtime.
  require "rubygems"
  require "bundler"
  Bundler.setup
end

bundle install parece funcionar bien ya que terminó con Your bundle is complete!.Pero al iniciar mi aplicación aparece el siguiente error:

$ ruby script/server

¿Que esta mal aquí?

Arrrg, simplemente presioné el botón de enviar y tuve una idea que resolvió el problema.El manual del paquete dice:[...] incluya lo siguiente al comienzo de su código". Para una aplicación Rails debe poner la parte mencionada en la parte inferior de config/environment.rb para configurar todo correctamente antes:

RAILS_GEM_VERSION = '2.3.5' unless defined? RAILS_GEM_VERSION

require File.join(File.dirname(__FILE__), 'boot')

Rails::Initializer.run do |config|
...
end

# Put the bundler related stuff here!
begin
  # Require the preresolved locked set of gems.
  require File.expand_path('../.bundle/environment', __FILE__)
rescue LoadError
  # Fallback on doing the resolve at runtime.
  require "rubygems"
  require "bundler"
  Bundler.setup
end
