How to use headless chrome with capybara and selenium

Chrome version: 59.0.3071.104

Using Cucumber, Capybara, Selenium to implement automation testing with Headless Chrome.

features/support/env.rb

require 'rubygems'require 'capybara/cucumber'Capybara.register_driver :selenium_chrome do |app|  Capybara::Selenium::Driver.new(app, :browser => :chrome, args: ['headless'])endCapybara.default_driver = :selenium_chrome

When running a cucumber test, it says:

WARN Selenium [DEPRECATION] :args or :switches is deprecated. Use Selenium::WebDriver::Chrome::Options#add_argument instead.

What is the correct way to use capybara and selenium with Headless Chrome. Thank you.

EDIT 1: I tried the following using Ruby-Binding, Capybara and Working Example. But it gives errors as well.

require 'rubygems'require 'capybara/cucumber'require 'selenium-webdriver'Capybara.register_driver :selenium_chrome do |app|  options = Selenium::WebDriver::Chrome::Options.new  options.add_argument('--headless')  driver = Selenium::WebDriver.for :chrome, options: options  Capybara::Selenium::Driver.new(    app,     browser: :chrome,     desired_capabilities: driver  )endCapybara.default_driver = :selenium_chrome

Error:

> undefined method `each' for> #<Selenium::WebDriver::Remote::Capabilities:0xd13baac> (NoMethodError)

Edit 2:Download the latest ChromeDriver 2.30

Using the example from ChromeDriver Capabilities& Chrome Command Line Switches I get an error.
