Watir 浏览器进程无法正常启动 (Windows)

Question

我已经在 Linux 中构建了一个简单的脚本，但现在我正试图让它在 windows 上运行。

密码是：

require 'watir-webdriver'
puts "Press enter when ready to continue"
gets
browser = Watir::Browser.start "http://www.google.com"
# do stuff

它在 Ubuntu 上完全符合预期。但是当我在 Windows 上尝试时，Firefox 进程启动，但在你看到 Firefox window 之前就死了。这是 Ruby 在此 Windows 安装上的全新安装，我以前从未在这台机器上使用过它。

可能是什么问题？

编辑：根据要求进行命令行跟踪。

那是 Firefox 中的 this bug。您的选择是：

等待 Firefox 47 中的补丁
降级到 Firefox 46
使用 Marionette 而不是 Firefox 驱动程序（该驱动程序已被弃用，很快将无法与新版本的 Firefox 一起使用）
使用Chrome

要尝试 marionette，请下载 geckodriver 并执行：

browser = Watir::Browser.new :firefox, marionette: true
