selenium.common.exceptions.SessionNotCreatedException：消息：session 未创建：此版本的 ChromeDriver 仅支持 Chrome 版本 83

Question

So this is my first time working with selenium, and I get the chromedriver browser to open fo a quarter of a second and then it closes, even it I give it a webpage to load or I tell it to sleep. It also gives me a SessionNotCreatedException.

Code:

from selenium import webdriver
import time

class TestBot():
    def __init__(self):
        self.driver = webdriver.Chrome()
        self.driver.get('http://www.google.com/')
        time.sleep(5)

Error:

>>> bot = TestBot()

selenium.common.exceptions.SessionNotCreatedException: Message: session not created: This version of ChromeDriver only supports Chrome version 83

I've tried adding Chromedriver as a path variable and that didn't work. I can start a chromedriver session just fine in cmd.

Answer 1

I think you should try running Selenium with MozillaFirefox,you also will need to install Geckodriver, which is a software that acts as a bridge between Firefox and selenium.

Answer 2

I was looking at the wrong version of chrome, turns out I have version 81, so I installed webdriver-manager and that works

Answer 3

as we see in the last line:

selenium.common.exceptions.SessionNotCreatedException: Message: session not created: This version of ChromeDriver only supports Chrome version 83

try to:

• update Chrome to last version so selenium too

• use geckodriver.exe for chrome, and put inside a folder then try:

self.driver = webdriver.Chrome(r"c:\your\geckodriver\path\withput\")

Answer 4

This error message...

selenium.common.exceptions.SessionNotCreatedException: Message: session not created: This version of ChromeDriver only supports Chrome version 83

...implies that the ChromeDriver was unable to initiate/spawn a new Browsing Context ie Chrome Browser session.

Analysis

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

• You are using ChromeDriver 83.0
• Release Notes of ChromeDriver 83.0 clearly mentions the following:

Supports Chrome version 83

Most possibly the Chrome Browser haven't been updated toChrome v83.0 yet as a part of the recent push and still isChrome v81.0

• Your Selenium Client version is unknown to us.

So there is a clear mismatch between ChromeDriver v83.0 and the Chrome Browser v81.0

---

Solution

Ensure that:

• Selenium is upgraded to current levels Version 3.141.59 .
• ChromeDriver is updated to current ChromeDriver v83.0 level.
• Chrome is updated to current Chrome Version 83.0 level. (as per ChromeDriver v83.0 release notes )
• If your base Web Client version is too old, then uninstall it and install a recent GA and released version of Web Client .
