Importing library 'Browser' failed: ModuleNotFoundError: No module named 'Browser'

i got this error while runing my code in azure devops although it works normally in my local machine,
Importing library ‘Browser’ failed: ModuleNotFoundError: No module named ‘Browser’

I checked my installation for browser library ,python and node js
I’m using python 3.9 and browser 14 ,node 16

did you execute “rfbrowser init” after the isntallation?

And are you sure, that you have the correct python environment?
Maybe you have two times python on your computer?

you are right there was 2 times python In my server and problem is solved but it gave me the below
