我正在学习使用Selenium来做基本的事情,例如截取屏幕,抓取和测试,并希望将它与无头Chrome一起使用,Chrome现在从Chrome 59开始就是稳定的.

我已经能够使用'selenium-webdriver'宝石和chromedriver截取屏幕截图,但不是无头.

这是我正在运行的ruby脚本,它在开始初始化驱动程序后挂起

require 'rubygems'
require 'selenium-webdriver'

Selenium::WebDriver.logger.level = :debug
p 'initializing driver'
driver = Selenium::WebDriver.for :chrome, switches: %w[--headless --disable-gpu --screenshot --hide-scrollbars]
p 'navigating to Google'
driver.navigate.to "http://google.com"  
driver.save_screenshot("./screen.png")
driver.quit

和日志的输出:

:> ruby rubytest.rb
