when I am going to run odoo using ./odoo-bin -c /etc/odoo-server.conf

I encounter with following error:

  1. Traceback (most recent call last):

Odoo 12 python requirement use babel=2.3.4 and this library uses  MutableMapping from collections.abc module in python which already deprecated in 3.8.

Babel library already changed it in V2.9.1 and using ABCs from collections instead of collections.abc is deprecated

https://github.com/python-babel/babel/commit/65d6bf39f2a2b4bbbbc02cd1e00c44ce9d7c1c5b#diff-efc3eeaaafe0e86beabfcbded9caeaab1a41af159501fc4d973a2cf9c577e89a

You can try to uninstall babel=2.3.4 and install any version of babel after 2.9.1

Or you can install python3.7 and it will work.
