在 watir webdriver 中使用无头 chrome

Question

在 watir 文档（http://watir.com/guides/chrome/）中，已经提到做

Watir::Browser.new :chrome, headless: true

将使我们能够使用无头 chrome

这似乎不起作用。

我收到如下错误

2.4.0 :001 > require 'watir'
 => true 
2.4.0 :002 > Watir::Browser.new :chrome, headless: true
ArgumentError: unknown option: {:headless=>true}

我拥有的 chrome 版本是 59.0.3071.115

我拥有的 chrome 驱动程序版本是

ChromeDriver 2.20.353124 (035346203162d32c80f1dce587c8154a1efa0c3b

使用

selenium-webdriver 3.4.3

watir 6.7.1 (was 6.3.0)

Answer 1

这个问题已经解决了。似乎 watir 版本6.7.1支持此功能，但不支持6.3.0

当我拥有最新版本的watirgem 时，它工作正常
