RSelenium 对服务器的无效调用

Question

当我运行R中的介绍代码时，

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

remDr$navigate("http://www.google.com")

我收到错误

Invalid call to server. Please check you have opened a browser.

Answer 1

我添加了行

remDr$open()

在remoteDriver赋值和remDr$navigate()命令之间，除了编辑系统路径，还能够成功。
