我正在尝试在Windows 7和Mac OS X中运行RSelenium。我已经阅读了RSelenium的一些简单的操作指南，当我重复他们的代码时，RStudio会抛出以下警告/错误消息：
checkForServer()
startServer()
Warning message:
running command '"java" -jar "C:/Users/TEMP/Documents/R/win-library/3.2/RSelenium/bin/selenium-server-standalone.jar" -log "C:/Users/TEMP/Documents/R/win-library/3.2/RSelenium/bin/sellog.txt"' had status 127
remDr <- remoteDriver()
remDr$open()
[1] "Connecting to remote server"
Undefined error in RCurl call.
Error in queryRD(paste0(serverURL, "/session"), "POST", qdata = toJSON(serverOpts)) :
但是，Mac只会出现错误消息，而不是警告。
从OP的答案中复制.. @hrbrmstr这是devtools :: session_info（）的输出。
> devtools::session_info()
