This is the presented error:

"Unable to install module "whatsapp" because an external dependency is not met: Python library not installed: phonenumbers"

I did everything in the odoo, from pip3 install phonenumbers to checking if python in the environment to testing inside the server a code of python.

all of them worked except trying to install the whatsapp module and it would result in the same issue.

in addition I tried to reboot the server and run it again, still nothing changed
