Session not created: This version of ChromeDriver only supports Chrome version 74 error with ChromeDriver Chrome using Selenium
I'm trying to run RSelenium using the rsDriver function, but when I run rD <- rsDriver() I get a message”this version of chromedriver only supports chrome version 83” telling me I need a newer version of Chrome:

Selenium message:session not created: This version of ChromeDriver only supports Chrome version 74
(Driver info: chromedriver=74.0.3729.6 (255758eccf3d244491b8a1317aa76e1ce10d57e9-refs/branch-heads/3729@{#29}),platform=Mac OS X 10.14.3 x86_64)
Could not open chrome browser.
Client error message:
Summary: SessionNotCreatedException
Detail: A new session could not be created.
Further Details: run errorDetails method
Check server log for further details.
The error message appears to say that I need Chrome version 74.0.3729.6, but when I look in Chrome's settings, it tells me that I'm running the latest stable version (73.0.3683.75). Upon further googling, 74.0.3729.6 is a pre-release dev version of Chrome: do I need to install this in order to use ChromeDriver with RSelenium?
I'm not wedded to the idea of using Chrome, but I haven't been able to get rsDriver to use Firefox: when I specify browser = "firefox", rsDriver gives me the same error message about ChromeDriver not supporting my version of Chrome.

I just ran into the same kind of error using RSelenium::rsDriver()'s default chromever = "latest" set which resulted in the failed attempt to combine chromedriver 75.0.3770.8 with latest google-chrome-stable 74.0.3729.157:
session not created: This version of ChromeDriver only supports Chrome version 75
Since this obviously seems to be a recurring and pretty annoying issue, I have come up with the following workaround to always use the latest compatible ChromeDriver version:
rD <- RSelenium::rsDriver(browser = "chrome",
chromever =
system2(command = "google-chrome-stable",
args = "--version",
stdout = TRUE,
stderr = TRUE) %>%
stringr::str_extract(pattern = "(?<=Chrome )\d+\.\d+\.\d+\.") %>%
magrittr::extract(!is.na(.)) %>%
stringr::str_replace_all(pattern = "\.",
replacement = "\\.") %>%
paste0("^", .) %>%
stringr::str_subset(string =
binman::list_versions(appname = "chromedriver") %>%
dplyr::last()) %>%
as.numeric_version() %>%
max() %>%
as.character())
The above code is only tested under Linux and makes use of some tidyverse packages (install them beforehand or rewrite it in base R). For other operating systems you might have to adapt it a bit, particularly replace command = "google-chrome-stable" with the system-specific command to launch Google Chrome:
On macOS it should be enough to replace
command = "google-chrome-stable" with command = "/Applications/Google Chrome.app/Contents/MacOS/Google Chrome" (untested)
On Windows, a platform-specific bug prevents us from calling the Google Chrome binary directly to get its version number. Instead, do the following:
rD <- RSelenium::rsDriver(browser = "chrome",
chromever =
system2(command = "wmic",
args = 'datafile where name="C:\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\Program Files (x86)\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\Google\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\Chrome\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\Application\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\chrome.exe" get Version /value',
stdout = TRUE,
stderr = TRUE) %>%
stringr::str_extract(pattern = "(?<=Version=)\d+\.\d+\.\d+\.") %>%
magrittr::extract(!is.na(.)) %>%
stringr::str_replace_all(pattern = "\.", replacement = "\\.") %>%
paste0("^", .) %>%
stringr::str_subset(string = binman::list_versions(appname = "chromedriver") %>%
dplyr::last()) %>%
as.numeric_version() %>%
max() %>%
as.character())
Basically, the code just ensures the latest ChromeDriver version matching the major-minor-patch version number of the system's stable Google Chrome browser is passed as a chromever argument. This procedure should adhere to the official ChromeDriver versioning scheme. Quote:
ChromeDriver uses the same version number scheme as Chrome (...)
Each version of ChromeDriver supports Chrome with matching major, minor and build version numbers. For example, ChromeDriver 73.0.3683.20 supports all Chrome versions that start with 73.0.3683.
