I chucked and rebuit my entire virtual environment, to no effect.

can you try:

from webdriver_manager.chrome import ChromeDriverManager
webdriver.Chrome(service=Service(ChromeDriverManager().install()))

[hebozhe]

can you try:

from webdriver_manager.chrome import ChromeDriverManager
webdriver.Chrome(service=Service(ChromeDriverManager().install()))

I didn't mess up the install command. The traceback clearly shows one line below where my snippet begins that webdriver_manager\chrome.py was accessed and started throwing its error there.

@hebozhe clarifications needed.

[aleksandr-kotlyar]

I got the root cause of your issue, @hebozhe Somehow you got broken drivers.json file on your environment. Most likely someone edited it manually. Please clean all .wdm folders and other places you could save webdrivers by webdriver-manager. And version 3.8.5+ please. 3.8.5 is latest stable for now.
