Selenium server couldn't be started

I updated R then I got the problem with rselenium

> system(paste0("kill $(lsof -i :4567 | grep LISTEN | awk '{print $2}')"))
sh: 1: kill: Usage: kill [-s sigspec | -signum | -sigspec] [pid | job]... or
kill -l [exitstatus]
> rD <- rsDriver(chromever = Sys.getenv('CHROME_VERSION'), extraCapabilities = eCaps)

Error in wdman::selenium(port = port, verbose = verbose, version = version,  :
  Selenium server  couldn't be started

I tried to put verbose = FALSE into rsDriver but didn't work

> system(paste0("kill $(lsof -i :4567 | grep LISTEN | awk '{print $2}')"))
sh: 1: kill: Usage: kill [-s sigspec | -signum | -sigspec] [pid | job]... or
kill -l [exitstatus]
> rD <- rsDriver(verbose = FALSE, chromever = Sys.getenv('CHROME_VERSION'), extraCapabilities = eCaps)
Could not open chrome browser.

Solution

  • I had the same issue and the solution the problem is found here: https://github.com/ropensci/RSelenium/issues/264#issuecomment-1344003384

    The return value gives interesting info about chromedriver and chrome version too. If there is a mismatch it will fail too. But that is another topic.

    library(wdman)
selenium(retcommand=T)
