Rselenium remDR $ open()错误

Question

我正在运行此代码:

devtools::install_github("ropensci/RSelenium")
require(RSelenium)
RSelenium::checkForServer(update=T)
RSelenium::startServer()
remDr <- remoteDriver()
remDr$open()

并收到此错误:

[1] "Connecting to remote server"
Error:   Summary: UnknownError
     Detail: An unknown server-side error occurred while processing the command.
     class: org.openqa.selenium.WebDriverException

尽管搜索(诚实!),但我无法找出为什么会发生这种情况.任何人都可以提供的任何帮助将不胜感激.

谢谢!
