Answer 1

May be your web driver manager is outdated.

---

Uninstall your web driver manager by...

pip uninstall webdriver_manager   

...then again install...

pip install webdriver_manager

Install webdriver-manager:

pip install webdriver-manager, pip install selenium

And then:

# selenium 4
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.chrome.service import Service
from webdriver_manager.chrome import ChromeDriverManager

option = webdriver.ChromeOptions()
option.add_argument("start-maximized")


driver = webdriver.Chrome(service=Service(ChromeDriverManager().install()),options=option)
driver.get('https://www.google.com/')

Where does it install the ChromeDriver then on the linux/ubuntu? Is there a way to find it out? – Reid

@VikasGoel On macos it is in ~/.wdm – Incomprehensive

On Linux, it is also ~/.wdm – Crossly

Just an extra note (for those fixing legacy code - like me) - From Selinium 3 to Selinium 4, there was a change in how WebDriver-Manager's initialization is conducted - as shown in the answer. – Darien

Answer 2

Maybe your webdriver manager is outdated. Uninstall webdriver_manager:

pip uninstall webdriver_manager  

Then install again:

pip install webdriver_manager 

And install selenium:

pip install selenium

Answer 3

I got the answer from https://gemini.google.com

The issue was using driver = webdriver.Chrome(ChromeDriverManager().install(), options=chrome_options)

Google gemini said:

Since ChromeDriverManager().install() already returns the path to the ChromeDriver executable, there's no need to pass it as the first argument. Simply remove it:

Python

driver = webdriver.Chrome(options=chrome_options)

I replaced driver = webdriver.Chrome(ChromeDriverManager().install(), options=chrome_options)

With driver = webdriver.Chrome(options=chrome_options) and it worked again.
