Run Watir-Webdriver in rails

I need to get data from a page that is dynamically created, one solution I found is Watir.

The following code works fine from irb:

require 'rubygems'
require 'watir-webdriver'
require 'headless'

Headless.ly do
  browser = Watir::Browser.new :firefox
  browser.goto "google.com"
  browser.close
end

in case I try to start it from the rails application, do the following task:

Gemfile:

gem 'headless'
gem 'watir-webdriver'

Act:

def test_action
    Headless.ly do
          browser = Watir::Browser.new(:firefox)
          browser.goto "google.com"
          browser.close
     end
end

have the following output:

My project has the same mistakes with you

I found this question posed by the selenium-webdriver gem

and verion should be "2.20.0"

If the gem version is higher than this, this error will occur

just put this code in the initializer directory, works with 'watir-webdriver', '0.5.5'

require 'childprocess'
require 'tmpdir'
require 'fileutils'
require 'date'

require 'multi_json'
require 'selenium/webdriver/common'

module Selenium
  module WebDriver

    if MultiJson.respond_to?(:load)
      # @api private
      def self.json_load(obj)
        MultiJson.decode(obj)
        #MultiJson.load(obj) here was mistake
      end
    else
      # @api private
      def self.json_load(obj)
        MultiJson.decode(obj)
      end
    end

  end
end

, multi_json, :

bundle update multi_json

For me, updating from version 1.0.3 to 1.3.5 solved the problem.
