I get a blank page when trying to navigate to any page, and I can't find any DOM element. I've tried with 2 different machines I already had, both of them Ubuntu 14.04 Server. 

library("RSelenium")
pJS <- phantom()
nav <- remoteDriver(remoteServerAddr = "localhost", port = 4444, browserName = "phantomjs")

nav$open()
nav$navigate("https://airenetworks.es/")
geco <- nav$findElement(using = "partial link text", value = "Oficina Virtual")
geco$clickElement()

The error in the last line of this code is: 

Error:   Summary: NoSuchElement
     Detail: An element could not be located on the page using the given search parameters.
     class: SessionReqHand

Installed RSelenium via install.packages("RSelenium") and PhantomJS via apt-get install phantomjs. The demo("PhantomJSUserAgent") also fails.

If in this state I perform a nav$screenshot(display = TRUE) the image I get is all white. If you need the image data there it is:

If you need more info, please ask. Thank you!

我终于发现我必须将其编码为：

pJS <- phantom(extras = "--ignore-ssl-errors=true --ssl-protocol=tlsv1")
Sys.sleep(2)
nav <- remoteDriver(remoteServerAddr = "localhost", port = 4444, browserName = "phantomjs")

您必须将协议设置为tlsv1. 同样重要的是让它休眠一两秒钟，因为它需要时间才能启动（经过一些试验和错误，我意识到我需要Sys.sleep(2)在调用remoteDriver函数之前）
