spork + cucumber-rails = "undefined method `World' for main:Object (NoMethodError)"

README.md

Here's the steps I took to create this error:

rvm use ruby-1.9.2-p180@sporkfail --create
gem install bundler
gem install rails --pre
rails new sporkfail
cd sporkfail

# edit Gemfile

bundle install
rails generate cucumber:install --spork
rails generate cucumber:feature post title:string body:text published:boolean
rails generate scaffold post title:string body:text published:boolean
rake db:migrate

bundle exec rake cucumber
# works

bundle exec spork
# error

env.rb

# It is recommended to regenerate this file in the future when you upgrade to a

# instead of editing this one. Cucumber will automatically load all features/**/*.rb
# files.

require 'rubygems'
require 'spork'

  require 'cucumber/rails'


  # Capybara defaults to XPath selectors rather than Webrat's default of CSS3. In
  # order to ease the transition to Capybara we set the default here. If you'd
  # prefer to use XPath just remove this line and adjust any selectors in your
  # steps to use the XPath syntax.
  Capybara.default_selector = :css

end

  # By default, any exception happening in your Rails application will bubble up
  # to Cucumber so that your scenario will fail. This is a different from how 
  # your application behaves in the production environment, where an error page will 
  # be rendered instead.
  #
  # Sometimes we want to override this default behaviour and allow Rails to rescue
  # exceptions and display an error page (just like when the app is running in production).
  # Typical scenarios where you want to do this is when you test your error pages.
  # There are two ways to allow Rails to rescue exceptions:
  #
  # 1) Tag your scenario (or feature) with @allow-rescue
  #
  # 2) Set the value below to true. Beware that doing this globally is not
  # recommended as it will mask a lot of errors for you!
  #
  ActionController::Base.allow_rescue = false
  
  # Remove/comment out the lines below if your app doesn't have a database.
  # For some databases (like MongoDB and CouchDB) you may need to use :truncation instead.
  begin
    DatabaseCleaner.strategy = :transaction
  rescue NameError
    raise "You need to add database_cleaner to your Gemfile (in the :test group) if you wish to use it."
  end
  
  # You may also want to configure DatabaseCleaner to use different strategies for certain features and scenarios.
  # See the DatabaseCleaner documentation for details. Example:
  #
  #   Before('@no-txn,@selenium,@culerity,@celerity,@javascript') do
  #     DatabaseCleaner.strategy = :truncation, {:except => %w[widgets]}
  #   end
  #
  #   Before('~@no-txn', '~@selenium', '~@culerity', '~@celerity', '~@javascript') do
  #     DatabaseCleaner.strategy = :transaction
  #   end
  #
end
