This version of ChromeDriver only supports Chrome version 79 - Python

Question

This error drives me crazy. My code is:

from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
import chromedriver_binary
from selenium.webdriver.common.by import By
import time
from influxdb import InfluxDBClient
chrome_options = Options()
chrome_options.add_argument("--headless")
chromedriver_binary = 
"/home/dario/scripts/cron_run/web_app_login_checker/chromedriver/chromedriver"
driver = webdriver.Chrome(chromedriver_binary, options=chrome_options)

If I do:

 ./chromedriver -v
 ChromeDriver 79.0.3945.36 (3582db32b33893869b8c1339e8f4d9ed1816f143-refs/branch- 
 heads/3945@{#614})

It's the right version.

Full traceback is:

None of the already discussed topics here on Stack Overflow helped me.

Answer 1

The problem is the Chrome browser version, not the ChromeDriver version. You need to update it to version 79, or downgrade the ChromeDriver. You can find here the matching versions.

Answer 2

If you are getting this error when you run stuffs on automated cluster and you are downloading the stable version of the google chrome every time then you can use the below shell script to download the compatible version of the chrome driver dynamically every time even if the stable version of the chrome gets updated. You could do something similar to this python to make it work.

%sh
#downloading compatible chrome driver version
#getting the current chrome browser version
**chromeVersion=$(google-chrome --product-version)**
#getting the major version value from the full version
**chromeMajorVersion=${chromeVersion%%.*}**
# setting the base url for getting the release url for the chrome driver
**baseDriverLatestReleaseURL=https://chromedriver.storage.googleapis.com/LATEST_RELEASE_**
#creating the latest release driver url based on the major version of the chrome
**latestDriverReleaseURL=$baseDriverLatestReleaseURL$chromeMajorVersion**
**echo $latestDriverReleaseURL**
#file name of the file that gets downloaded which would contain the full version of the chrome driver to download
**latestDriverVersionFileName="LATEST_RELEASE_"$chromeMajorVersion**
#downloading the file that would contain the full release version compatible with the major release of the chrome browser version
**wget $latestDriverReleaseURL** 
#reading the file to get the version of the chrome driver that we should download
**latestFullDriverVersion=$(cat $latestDriverVersionFileName)**
**echo $latestFullDriverVersion**
#creating the final URL by passing the compatible version of the chrome driver that we should download
**finalURL="https://chromedriver.storage.googleapis.com/"$latestFullDriverVersion"/chromedriver_linux64.zip"**
**echo $finalURL**
**wget $finalURL**

I was able to get the compatible version of chrome browser and chrome driver using the above approach when running scheduled job on the databricks environment and it worked like a charm without any issues.

Hope it helps others in one way or other.

1. Check your chrome version

   2. Download the same version of the chrome driver Check the latest driver here

   3. Update your driver in the reference folder.

In my case, I am using the windows 10 and python I've updated with the latest chromedriver.exe file (for Chrome v83)

Answer 4

This error message...

selenium.common.exceptions.SessionNotCreatedException: Message: session not created: This version of ChromeDriver only supports Chrome version 79

...implies that the ChromeDriver was unable to initiate/spawn a new Browsing Context i.e. Chrome Browser v79.x session.

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

• You are using chromedriver=79.0.3945.36
• Release Notes of chromedriver=79.0.3945.36 clearly mentions the following :

Supports Chrome version 79

• Presumably you are using the latest Version 78.0.3904.108 (Official Build)

So there is a clear mismatch between the ChromeDriver v79.0.3945.36 and Chrome Browser v78.0.3904.108

---

Solution

There are two possible solutions:

• Either you need to downgrade ChromeDriver to ChromeDriver 78.0.3904.105
• Download, install and use Chrome from the Chrome Release Channels
  • Linux Stable channel
  • Linux Beta channel
  • Linux Development channel
  • latest build
