我目前正在设置一些Cucumber测试，我的Hook文件包含以下内容：
require 'watir'
Before do
@browser = Watir::Browser.new :chrome
end
After do
@browser.close
end
当我运行我的功能文件时，我得到以下内容：
cannot load such file -- watir (LoadError)

我不确定为什么在安装Watir时会发生此错误。当我需要Watir并使用ruby文件运行脚本时，它可以正常工作。只要使用功能它就会发生错误。
当任何帮助将不胜感激。

这不是您问题的直接答案，但适用于您在运行黄瓜时尝试启动浏览器的位置。除非你想要为每个场景启动浏览器的开销，否则我建议在support / env.rb中启动浏览器然后在before hook中你可以做一些事情，比如清除cookie以获得相当于每个场景的新浏览器
否则，如果您在每个方案开始时打开浏览器，并在结束时关闭它，那么由于每个方案启动浏览器会话所需的时间，您的功能执行起来会慢得多。
