Hi fellows,
I tried my first steps with ansible folowing to this manual:

https://dokuwiki.nausch.org/doku.php/centos:ansible:first

When I try ro rn this: ansible rhel8 -m shell -a “/usr/bin/ls -alF /root/”

I get: File “/usr/bin/ansible”, line 60, in
import ansible.constants as C
File “/usr/lib/python3.6/site-packages/ansible/constants.py”, line 19, in
from ansible.config.manager import ConfigManager, ensure_type, get_ini_config_value
File “/usr/lib/python3.6/site-packages/ansible/config/manager.py”, line 34, in
from ansible.inventory.data import InventoryData

from ansible.utils.display import Display
File “/usr/lib/python3.6/site-packages/ansible/utils/display.py”, line 40, in
from ansible.utils.color import stringc
File “/usr/lib/python3.6/site-packages/ansible/utils/color.py”, line 26, in
if C.ANSIBLE_NOCOLOR:
AttributeError: module ‘ansible.constants’ has no attribute ‘ANSIBLE_NOCOLOR’

My host.yml and /etc/ansible/hosts you can see here**: https://pastebin.com/SqvMW4ca**

How can I fix this?

Many thanks in advance

You seem to be running Ansible with an old Python version (3.6).
According to

    https://docs.ansible.com/ansible/latest/installation_guide/intro_installation.html#control-node-requirements

you should use Python 3.8 or newer on the control node, so that's
probably the first thing you should try.
