Python 3.9 Post Install fails

[rwachs]

I am attempting to get a working version of Python 3.X installed on my iMac currently running 10.15.7 (Catalina) to run one script. I have brew installed as well as Python 3.9. When I try to take the next step and run the post install I get an error,"

Warning: The post-install step did not complete successfully
You can try again using:
brew postinstall [email protected]

Adding the "@3.9" still doesn't show a completed process. The Debug script generates the following:

brew postinstall --debug node

Are you trying to post-install python or node?

For node, try brew reinstall node, as it looks like your npm directory got nuked somehow.

For python, you'd have to show us the correct debug output.

Well, thank you. I tried the reinstall node command and I think I am at least one step closer. I am not conversant in python (obviously) and am just trying to get an install to run one script each month. Quite an adventure! Thank you again for your time and assistance!
