使用 watir-webdriver 运行以下ruby代码时收到"Gateway Timeout"错误 .
require 'watir-webdriver'
browser = Watir::Browser.new :ff
错误说明：
服务器错误 - 此时无法访问服务器127.0.0.1 . 请重试请求或与您的管理员联系 .
我有一种感觉，公司代理正在干扰Watir . 也许Firefox正在尝试连接到在某些非标准端口上本地运行的Watir，并且代理干预并且无法解析地址127.0.0.1 . 这只是猜测 .
任何人都有此错误的经验或获得 watir-webdriver 工作的建议 . 有没有人成功运行 watir-webdriver 代理？
这是堆栈跟踪的错误：
