Question

我已经有红宝石和硒一段时间了。试图实施无头而且失败了。甚至来自网络的简单例子。在几台计算机上使用Windows 10，包括全新的加载适用资源的计算机。这是测试代码。

require 'selenium-webdriver'
options = Selenium::WebDriver::Chrome::Options.new(args: ['headless'])
puts "I'm here"
driver = Selenium::WebDriver.for(:chrome, options: options)
puts "Now I'm here"
driver.get('http://stackoverflow.com/')
puts driver.title
driver.quit

这是我得到的结果。我的应用程序运行正常，不会无头。
