好的，所以我正在尝试使用 selenium 解析网站。我将在 python 中执行此操作，当我使用 firefox 浏览器时它可以正常工作。我可以浏览网站并很好地解析它。
page = webdriver.Remote(command_executor='http://127.0.0.1:4444/wd/hub',desired_capabilities=DesiredCapabilities.FIREFOX)
但是，由于我必须获取所有 24something 国家/地区的信息，我希望能够使用 HTMLUNIT 来完成它，但这给了我一个错误。当我运行以下代码时它工作正常
page = webdriver.Remote(command_executor='http://127.0.0.1:4444/wd/hub',desired_capabilities=DesiredCapabilities.HTMLUNITWITHJS)
（注意我放了'HTMLUNITWITHJS'..它仍然给我同样的错误）但是一旦我尝试这样做
page.get("http://www.investmentmap.org")
它给了我以下错误

这是我的源代码

哦还有一件事。我在 Windows 7 中的 cygwin 上运行 python，但即使我在我的 mac 中执行此操作，我也会遇到同样的错误。我也在使用 selenium-server-standalone java 服务器。这是它转储的
