运行Chrome的watir webdriver脚本时出错

Question

我在Chrome下运行脚本,但在运行脚本时显示错误

要求'watir-webdriver'

b = Watir::Browser.new:chrome
b.goto 'bit.ly/watir-webdriver-demo'
b.text_field(:id => 'entry_0').set 'your name'
b.select_list(:id => 'entry_1').select 'Ruby'
b.select_list(:id => 'entry_1').selected? 'Ruby'
b.button(:name => 'submit').click
b.text.include? 'Thank you'

运行脚本时出现以下错误

C:/Ruby193/lib/ruby/gems/1.9.1/gems/selenium-webdriver-2.21.2/lib/selenium/webdr
iver/chrome/service.rb:19:in `executable_path': Unable to find the chromedriver

好吧,错误信息说明了一切.你必须安装chromedriver:
