Using Rselenium on mac sierra

问题

It seems that every time I update my OS, R, or any browsers Rselenium stops working. I can no longer use it with any browser -Firefox, Chrome, or PhantomJS. I've posted my code below.

Session Info:

sessionInfo()
R version 3.3.2 (2016-10-31)
Platform: x86_64-apple-darwin13.4.0 (64-bit)
Running under: macOS Sierra 10.12.2

locale:
[1] en_US.UTF-8/en_US.UTF-8/en_US.UTF-8/C/en_US.UTF-8/en_US.UTF-8

attached base packages:
[1] stats     graphics  grDevices utils     datasets  methods   base     

other attached packages:
[1] rvest_0.3.2.9000 xml2_1.0.0       RSelenium_1.6.2 

loaded via a namespace (and not attached):
 [1] httr_1.2.1     magrittr_1.5   R6_2.2.0       tools_3.3.2    curl_2.3       Rcpp_0.12.8   
 [7] jsonlite_1.2   caTools_1.17.1 openssl_0.9.6  bitops_1.0-6   XML_3.98-1.4  

My work flow is the following:

1. PhantomJS: install in terminal using node npm (install node npm with brew: brew install node)

   npm install -g phantomjs
   phantomjs --version #To check if it installed
       2.1.1  #It did
   

   Onto my R session:

   library(RSelenium) 
   ptm <- phantom() #also tried running checkForServer() and startServer() first but both were deprecated with no substitute stated...
   

[ERROR - 2017-01-06T01:55:35.240Z] GhostDriver - main.fail - {"line":85,"sourceURL":"phantomjs://code/main.js","stack":"global code@phantomjs://code/main.js:85:56"}

phantomjs://platform/console++.js:263 in error

    rd <- remoteDriver(browserName = 'phantomjs')
    rd$open()

[1] "Connecting to remote server" Error: Summary: UnknownError

2. Chromedriver: downloaded from https://chromedriver.storage.googleapis.com/index.html?path=2.27/ and binary file placed in /usr/local/bin

   rd <-remoteDriver(browserName = 'chrome')
   rd$open() #At this point, Google Chrome opens up for 1 second and then closes and an error pops up

3. Firefox: installed gecko driver in /usr/local/bin (without this the following code would produce an error indicating I needed the gecko driver installed)

   remDr <- remoteDriver$new()
   remDr$open() #a blank Firefox page opens up but then the following error is produced)
   

[1] "Connecting to remote server"

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

Error in checkError(res) : Undefined error in httr call. httr output: length(url) == 1 is not TRUE

Any help is much appreciated.

UPDATE

After upgrading Firefox to the beta version (51.0b11), I can browse successfully but the problems persist using Chrome and PhantomJS.
