【问题描述】：
我想提高 selenium 的性能（在 selenium-python 上工作）。所以我想切换到无头浏览器，因为 GUI 不是必需的。
我为phantomJS 设置路径变量并运行
driver = webdriver.PhantomJS()
收到error 后，我在初始化驱动程序时设置了路径和服务参数（经过几十个 stackoverflow 和 google 组
phantomjs_path = r"C:\Users\sachin.nandakumar\AppData\Local\Continuum\anaconda3\phantomjs\bin\phantomjs.exe"
service_args = [ '--proxy=10.118.132.29:80', '--proxy-type=http',]
driver = webdriver.PhantomJS(executable_path=phantomjs_path,service_args=service_args)
但我仍然遇到同样的错误。 （错误在下面详细说明）
后来我也尝试了HtmlUnitDriver。但同样的错误再次发生。
无头浏览器在代理（企业防火墙）后面工作是否存在任何问题？或者如果是关于一些身份验证问题，我没有找到解决这些问题的方法。
