RSelenium not working with Firefox

Question

I know my question is similar to this one, but he's trying to use Chrome while I'm trying to use Firefox (47.0.1).

So basically, I'm trying to use RSelenium. Here is my code :

> library(RSelenium)
> checkForServer()

> startServer()
> mybrowser <- remoteDriver()
> mybrowser$open()

And with that last line, I get the following error.

[1] "Connecting to remote server"
Error:   Summary: UnknownError
         Detail: An unknown server-side error occurred while processing the command.
         class: org.openqa.selenium.WebDriverException

I tried removing-reinstalling the RSelenium package. I also tried what this answer recommends, with no result.

Thanks in advance.

Answer 1

Can you try installing from github:

devtools::install_github("ropensci/RSelenium")

Then run

RSelenium::checkForServer(update = TRUE)

then retry. Selenium recently put a beta version of Selenium 3.0 on the download tree which was unaccounted for see https://github.com/ropensci/RSelenium/issues/79. I will look to update a new version to CRAN once some additional fixes have been incorporated.

UPDATE:

There is a new version of RSelenium on CRAN now.

install.packages("RSelenium")
library(RSelenium)
checkForServer(update = TRUE)

selServ <- startServer()
mybrowser <- remoteDriver()
mybrowser$open()
mybrowser$navigate("http://www.google.com")
mybrowser$close()
selServ$stop()
