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，我看到以下错误。

在公司代理下，我们将面临这样的问题。

407 Proxy Authentication Required 是一个 HTTP 响应状态代码，表示服务器无法完成请求，因为客户端缺少代理服务器的正确身份验证凭据，该代理服务器正在拦截客户端和服务器之间的请求。

选项 1：尝试使用 selenium-standalone npm 包。这类似于 webdriver-manager。

https://www.npmjs.com/package/selenium-standalone

全局安装这个包

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

（或者）
