RSelenium和Docker快速入門終端-無法連接到遠程服務器

Question

我正在嘗試Rselenium的初期工作。 我遵循了這篇文章中的指南：“ 無法執行rsDriver（連接被拒絕） ”

library(RSelenium)
#Let's Start
shell('docker pull selenium/standalone-firefox')
shell('docker run -d -p 4445:4444 selenium/standalone-firefox')
remDr <- remoteDriver(remoteServerAddr = "localhost", port = 4445L, browserName = "firefox")
remDr$open()
remDr$navigate("http://www.google.com")
remDr$getTitle()

但控制台打印：

> library(RSelenium)
> #Let's Start
> shell('docker pull selenium/standalone-firefox')
Using default tag: latest

我可以請求幫助嗎？

在cmd @FOR /f "tokens=*" %i IN ('docker-machine.exe env --shell cmd') DO @%i運行此命令@FOR /f "tokens=*" %i IN ('docker-machine.exe env --shell cmd') DO @%i ，然后嘗試。
