浏览器初始化失败，因为Selenium参数错误

Question

我在初始化Watir浏览器时突然出现错误。使用当前版本的watir-rails和selenium-webdriver gems。

初始化chrome无头浏览器时:

browser = Watir::Browser.new :chrome, args: %w[--headless --no-sandbox --disable-dev-shm-usage --disable-gpu --remote-debugging-port=9222]

我得到以下错误，似乎是由与Selenium的预期参数不一致引起的:

根据底部的警告和这篇文章，watir selenium:浏览器构造函数无法识别的参数，我已经尝试更改初始化:

BROWSER_OPTIONS = %w[--headless --no-sandbox --disable-dev-shm-usage --disable-gpu --remote-debugging-port=9222]
browser = Watir::Browser.new :chrome, options: {args: BROWSER_OPTIONS}

然而，我得到相同的错误(没有弃用警告)

问题是您需要Watir 7才能与Selenium 4一起工作。请升级到最新版本的Watir，它将正常工作。
