R 为什么可以'；我不能连接到Selenium服务器吗？

我的RSelenuium脚本今天停止工作了，我不明白为什么。下面的代码是我通常用来启动服务器的代码

library(RSelenium)

rd <- rsDriver(port = 4567L, browser = "chrome")

库（RSelenium）
rd您可以使用
binman
包删除版本：

> binman::list_versions("seleniumserver")
$generic
 [1] "3.0.0"       "3.0.0-beta4" "3.0.1"       "3.1.0"       "3.2.0"      
 [6] "3.3.0"       "3.3.1"       "3.4.0"       "3.5.0"       "3.5.1"      
[11] "3.5.2"       "3.5.3"       "3.6.0"      

> binman::rm_version("seleniumserver", "generic", "3.6.0")
Removing version: 3.6.0 from platorm: generic

运行
rsDriver
将重新下载损坏的JAR：

> rD <- rsDriver()

>rD您尝试过重新下载jar并重新启动服务器吗？@BryanOakley，谢谢您的快速回复。我删除并重新安装了RSelenium包，希望它能重新下载jar。有没有其他方法可以重新下载jar？再次感谢@BryanOakley，这非常有效！谢谢你的提示@jdharison，下次我会用的。
