Python: ModuleNotFoundError: No module named Rich

I am trying to use rich module to draw table in python3.9 in Linux.
However, I am getting:

Traceback (most recent call last):
  File "/opt/audit.py", line 12, in <module>
    fom rich.table import Table
ModuleNotFoundError: No module named 'rich'

I have both python 2.7 and 3.9 installed.
Command I run: python3.9 /opt/audit.py

I have verified I have rich installed. 
python3.9 -m pip list
Package        Version
-------------- -------
ansitable      0.9.7
colored        2.2.2
markdown-it-py 3.0.0
mdurl          0.1.2
pip            22.0.4
Pygments       2.15.1
rich           13.4.2
setuptools     58.1.0

python3.9 -m pip install rich --upgrade
Defaulting to user installation because normal site-packages is not writeable
Requirement already satisfied: rich in /disk2/users/python3.9/site-packages (13.4.2)
Requirement already satisfied: markdown-it-py>=2.2.0 in /disk2/users/python3.9/site-packages (from rich) (3.0.0)
Requirement already satisfied: pygments<3.0.0,>=2.13.0 in /disk2/users/python3.9/site-packages (from rich) (2.15.1)
Requirement already satisfied: mdurl~=0.1 in /disk2/users/python3.9/site-packages (from markdown-it-py>=2.2.0->rich) (0.1.2)

This is the start of the file and it fails on line 12:

import cx_Oracle
import configparser
import json
import os
import requests
import smtplib

from rich.table import Table
from email.message import EmailMessage
from pathlib import Path

If that package has been installed correctly, it is possible that python3 is not loading packages installed on that path due to some misconfiguration.

You can start troubleshooting by checking where the module was installed by pip:

$ python3 -m pip show rich

Name: rich
Version: 13.4.2
Summary: Render rich text, tables, progress bars, syntax highlighting, markdown and more to the terminal
Home-page: https://github.com/Textualize/rich

Location: /Library/Frameworks/Python.framework/Versions/3.11/lib/python3.11/site-packages
Requires: markdown-it-py, pygments
Required-by: 

If the Location path is also present in the sys.path list below, it means that this path is part of the global site-packages directories and python should be able to find the module when the interpreter runs:

$ python3 -m site

sys.path = [
    '/Users/Admin/workspace',
    '/Library/Frameworks/Python.framework/Versions/3.11/lib/python311.zip',
    '/Library/Frameworks/Python.framework/Versions/3.11/lib/python3.11',
    '/Library/Frameworks/Python.framework/Versions/3.11/lib/python3.11/lib-dynload',
    '/Library/Frameworks/Python.framework/Versions/3.11/lib/python3.11/site-packages',
]
USER_BASE: '/Users/Admin/Library/Python/3.11' (doesn't exist)
USER_SITE: '/Users/Admin/Library/Python/3.11/lib/python/site-packages' (doesn't exist)
ENABLE_USER_SITE: True

As you can see in this example, the Location path is the last entry on sys.path. However, if it's not in there, there's a chance it might be listed by the user site-package directories:

$ python3 -m site --user-site

If the Location path is not present in either of these site-packages, then you can try to add that path to one of them. But at this point I would seriously question the integrity of your python installation.
