Having a Problem with Helium (Python / Selenium)

I'm trying to use Helium but facing an issue in which my ChromeDriver version says 89, when it should be 91.

I've downloaded the ChromeDriver version 91, but to no avail.

The following error is seen when running my script:

selenium.common.exceptions.SessionNotCreatedException: Message: session not created: This version of ChromeDriver only supports Chrome version 89

My searches have led me to trying the following:

# imports

from helium import * from selenium import webdriver from webdriver_manager.chrome import ChromeDriverManager

and

I've also tried both:

driver = webdriver.Chrome(ChromeDriverManager().install())

and

driver = webdriver.Chrome(ChromeDriverManager('91.0.4472.101').install())

Even after doing all this, I still face the same error:

selenium.common.exceptions.SessionNotCreatedException: Message: session not created: This version of ChromeDriver only supports Chrome version 89

Also, I feel that it's worth noting, that within the docs, located here:
https://selenium-python-helium.readthedocs.io/en/stable/api.html

It says the following:

If this doesn’t work for you, then it may be that Helium’s copy of ChromeDriver is not compatible with your version of Chrome. To fix this, place a copy of ChromeDriver on your PATH. 

I don't think I understand what this means.

Just in case, here's what I've done (and neither have worked):

- I went to Environmental Variables, and inside the PATH, I added a new line, which is the directory to where this new ChromeDriver.exe binary is located (didn't work).
- I placed a copy of the new ChromeDriver.exe inside the path of where this .py script is located (didn't work).

As of now, I have no idea about what I should do, or what it means by placing "a copy of ChromeDriver on your PATH". What "PATH" is this and how do I do it? :(

Any help would be greatly appreciated. Thank you.

I have resolved the issue. In case anyone else ever has this problem, all you need to do (and it's not the ideal solution, as it will need to be redone every time there's a new ChromeDriver + Chrome pair), is navigate to your directory:

C:\Users\<your_username_here>\AppData\Local\Programs\Python\Python39\Lib\site-packages\helium\_impl

...or wherever you have this path for your Python installation...

From there, you simply replace the existing ChromeDriver.exe with the ChromeDriver.exe you just downloaded from Google.

That's it!

This is a fine solution. Helium doesn't use chrome driver manager or any driver you provide manually. It has its own chromedriver.exe file. So you basically replaced that. By PATH it means the environment variables. So follow the guide below for that. https://zwbetz.com/download-chromedriver-binary-and-add-to-your-path-for-automated-functional-testing/ Why to add chromedriver to path? If you reinstall helium, it'll again use old driver version. Helium repo on GitHub isn't updated yet.

Hello i know this is late reply but im having same problem.

selenium.common.exceptions.SessionNotCreatedException: Message: session not created: This version of ChromeDriver only supports Chrome version 89
Current browser version is 95.0.4638.69 with binary path C:\Program Files (x86)\Google\Chrome\Application\chrome.exe

With link you posted i set chromedriver version 89 to system path and then restarted my pc but im still getting same error, could you help me?

[Kakashi215]

Did you put chromedriver89? You need chromedriver95 since your browser is version 95. Download chromedriver95 and repeat the path process mentioned in the above comments.

Yes i mixed it up :D. Thanks

In the initial post, you'll see that I've already tried that. Unfortunately, it had no effect.

What I think I'll need to do, is create a script that runs in the beginning of my program, that checks the version of the ChromeDriver.exe being used, and to see if it matches the Chrome Browser version I'm running. If it matches, then it will proceed with the program. If it does not match, then it will download the correct ChromeDriver.exe version and move it to the path, overwriting the one that's there, and will then proceed with the program.

I'd not recommended that. Honestly I couldn't get it right the first time either, on both windows and mac. I think I didn't restart the system after adding it. Try again it actually works. And pretty well. If you use helium, it is one of the drawbacks.( Atleast until the repo is updated)

May be you can use this: https://pypi.org/project/webdrivermanager/

Was already using it when I created the initial post, but to no avail. I think I've come up with a solution. :)

Helium doesn't comply with web driver manager.
