RSelenium 无法打开浏览器 - R

如何解决RSelenium 无法打开浏览器 - R

我正在尝试使用 RSelenium 打开浏览器，我的代码在 Windows 上运行良好，但在 ubuntu 上无法运行，因为浏览器窗口无法打开。我已尝试使用 firefox 和 chrome 以及不同的端口。

library(RSelenium)

print("hey1")
rD <- rsDriver(browser="firefox",port=4545L,verbose=F)

print("hey2")
remDr <- rD[["client"]]

# open tab
remDr$open()   # errors here

输出：
