我正在尝试为我的角度应用程序自动化设置量角器。我在Node版本12上，我安装了量角器版本5.4.3。当我使用webdriver-manger update --proxy = blahblahproxy.com时，看到以下错误。

根据公司代理，我们将面临这样的问题。
407 Proxy Authentication Required是一个HTTP响应状态代码，指示服务器无法完成请求，因为客户端缺少正在拦截客户端和服务器之间请求的代理服务器的正确身份验证凭据。
选项1：尝试使用硒独立的npm软件包。这类似于webdriver-manager。
https://www.npmjs.com/package/selenium-standalone
全局安装此软件包
npm i -g selenium-standalone
然后下载/安装驱动程序
selenium-standalone install
然后启动服务器
selenium-standalone start
