SessionNotCreatedException: Message: session not created: This version of ChromeDriver only supports Chrome version 74 though Chrome v74 is installed

Question

I am starting to play around with selenium in python, and when i try to run this code it just pops an error that this version of chromedriver only supports version 74 of chr

Answer 1

This most commonly happens when chrome itself updates, but you have not updated the local ChromeDriver version to match your locally installed version of chrome.

In chrome, click the three dots, in the upper right, Help --> About Google Chrome. this will show your version of chrome. Or chrome://settings/help

Download the same version from https://chromedriver.storage.googleapis.com/index.html

Save that to the path defined, as in @DebanjanB's answer.

Answer 2

This error message...

selenium.common.exceptions.SessionNotCreatedException: 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=Windows NT 10.0.17134 x86_64)

...implies that the ChromeDriver expects the Chrome Browser version to be 74.

Your main issue is the incompatibility between the version of the binaries you are using as follows:

• You are using chromedriver=74.0.3729.6
• Release Notes of chromedriver=74.0.3729.6 clearly mentions the following :

Supports Chrome v74

Presumably you have multiple versions of Chrome browsers installed within your system and the version of Chrome browser installed at the default location which is accessed by chromedriver=74.0.3729.6 is not Chrome Browser v74.0. Hence you see the error.

Solution

The quickest solution would be to upgrade Chrome version installed at the default location to Chrome v74 level.

---

Alternative

As an alternative, if you want to use the Chrome browser binary installed in a non-standard location you can use an instance of ChromeOptions() with the binary_location property to point to the non-standard Chrome Browser location as follows:

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

options = Options()
options.binary_location = "C:\\Program Files\\Chrome\\chrome64_55.0.2883.75\\chrome.exe"
driver = webdriver.Chrome(chrome_options = options, executable_path=r'C:\path\to\chromedriver.exe')
driver.get('http://google.com/')
print("Chrome Browser Invoked")
driver.quit()

Answer 3

Simply go to chrome and check the version of chrome in your PC. (help -> About Chrome) Download the same version ChromeDriver from the below link ...

https://sites.google.com/a/chromium.org/chromedriver/downloads

then extract it and do paste in your script folder.

Answer 4

Run a search on your computer for "chromedriver" files, then delete all the searched files and copy the latest driver in your desired driver folder. This will solve the issue.
