Selenium Ruby Webdriver unable to run Chrome browser

Question

I am attempting to start a remote session for chrome and keep getting the same issue. The script isn't that complicated. I am wondering if it isn't some switch that might be set incorrectly. Below is a snippet of code I am using along with the error I am getting back (or part of it, very long). I see the browser attempt to open and then immediately close.

require "selenium-webdriver"
require "test/unit"

class PageLinks < Test::Unit::TestCase

  def setup
    @caps = Selenium::WebDriver::Remote::Capabilities.chrome
    @caps['chrome.switches'] = %w[--ignore-certificate-errors]
    @driver = Selenium::WebDriver.for( :remote, :url => 'http://localhost:4444/wd/hub', :desired_capabilities => @caps )
    @driver.manage.timeouts.implicit_wait = 200
    @driver.manage.timeouts.page_load = 200
    @wait = Selenium::WebDriver::Wait.new(:timeout => 200)
    @verification_errors = []
  end


  def teardown
    @driver.quit
  end


  def test_pagelinks
    @driver.get('http://www.yahoo.com')
    @driver.find_element(:link, "HOME").click

....

test_pagelinks(PageLinks):
Selenium::WebDriver::Error::UnknownError: [GET, HEAD, DELETE]

page_load超时设置是Firefox驱动程序中的一项实验性功能，Chrome驱动程序尚不支持。
