【问题描述】:
我在尝试连接 RSelenium 包时遇到问题:
> checkForServer()
> startServer()
$stop
function ()
{
tools::pskill(selPID)
}
<environment: 0x00000000039724d8>
$getPID
function ()
{
return(selPID)
}
<environment: 0x00000000039724d8>
> remDr <- remoteDriver()
> remDr$open()
[1] "Connecting to remote server"
Error: Summary: UnknownError
Detail: An unknown server-side error occurred while processing the command.
class: org.openqa.selenium.WebDriverException
我已经在我的计算机中配置了 Java,但 RSelenium 仍然失败。我已经阅读了这个网页上的很多帖子,但我仍然没有解决方案。我能做些什么?我的电脑是装有 Windows 10 Home Single 的华硕 X555LB。我附上会话信息:
> sessionInfo()

感谢您的帮助。

【问题讨论】:
-
你运行的是什么版本的火狐?如果是 friefox 48 则需要下载 gecko 驱动见github.com/ropensci/RSelenium/issues/81
-
我使用的是 firefox 46,但我正在避免升级它,因为 RSelenium 已在此版本上运行。
-
selenium server 的版本你改了吗?
