R selenium无法到达任何地方.这是第一步和我的输出:

library(RSelenium)
rD <- rsDriver()
# checking Selenium Server versions:
#   BEGIN: PREDOWNLOAD
# BEGIN: DOWNLOAD
# BEGIN: POSTDOWNLOAD
# checking chromedriver versions:

# checking phantomjs versions:

# [1] "Connecting to remote server"
# Error in checkError(res) :

我的操作系统是 Windows 8.1，我有 R 的 3.3.3 版。

我已经安装了 RSelenium 软件包，并尝试使用它来运行它：

library("RSelenium")
#start RSelenium server
startServer()
checkForServer()

我收到此错误：

Error: checkForServer is now defunct. Users in future can find the function in 
file.path(find.package("RSelenium"), "examples/serverUtils"). The
recommended way to run a selenium server is via Docker. Alternatively
see the RSelenium::rsDriver function.

RSelenium 打开的方式有什么变化吗？我搜索错误，我只找到了这个，但这对我没有帮助。我能做什么？

我尝试的另一种方法是从这里下载 chromedrive ' https://sites.google.com/a/chromium.org/chromedriver/downloads '

并使用此脚本： require(RSelenium) cprof <- getChromeProfile("C:/Users/Peri/Desktop/chromedriver/chromedriver.exe", "Profile 1")

require(RSelenium)
remDr <- remoteDriver(remoteServerAddr = "localhost" 
                      , port = 4444
                      , browserName = "chrome", extraCapabilities = …
