我安装了Wattir并尝试了该网站中给出的简单示例。
require 'watir'
browser = Watir::Browser.new :chrome
browser.goto 'https://www.google.com'
browser.text_field(title: 'Search').set 'Hello World!'
browser.button(type: 'submit').click
browser.quit
当我运行Ruby程序时，出现如下错误。

我在 Windows 7 上运行。
您正在针对chrome v59运行chromedriver=2.9.248315。 升级到chromedriver 2.30，支持 chrome v58-60。
