py39 create: /home/cessien/spark-nlp-phi-annotator/server/.tox/py39
ERROR: InterpreterNotFound: python3.9
________________________________________________________ summary _________________________________________________________
ERROR:   py37: commands failed
ERROR:   py38: commands failed
ERROR:  py39: InterpreterNotFound: python3.9

Steps to reproduce the issue

2. cd server
3. run the command 'tox'

Attempts to fix

• I have excluded the py37 and py39 environment from the tox.ini. The errror still shows when I run tox -e py38.
• I have also tried installing the latest version of tox. I think part of the error is with the sparknlp_jsl package.
• This package is installed using the secret_code appended to the URL.
• I have tried to see how to add the private index to the requirements.txt file
• I have tried adding a higher version of pytest that supports python 3.7+
