[issue45267] New install Python 3.9.7 install of Sphinx Document Generator fails

[Paul Broe]

New submission from Paul Broe <pcbroe at gmail.com>:

Brand new build of Python 3.9.7 on RHEL 7.  Placed in /usr/local/python3

Created new python environment

cd /usr/opt/oracle/
 python3 -m venv py3-sphinx
source /usr/opt/oracle/py3-sphinx/bin/activate
Now verify that python is now linked to Python 3.
In this virtual environment python  python3
python -V
Python 3.9.7

I installed all the pre-requisites correctly for Sphinx 4.2.0
See the output of the command in the attached file
command:
pip install -vvv --no-index --find-link=/usr/opt/oracle/downloads/python-addons sphinx
