NotADirectoryError: [Errno 20] Not a directory: '/Users/name/python' & The operation can’t be completed because the original item for “python” can’t be found.

After upgrading to Python 3.11.5, I encountered compatibility issues. After some research, found it was likely due to site-packages being installed via the normal python3.11 -m pip install x but python3.11 being (at that time) installed via homebrew.

I've since uninstalled python3.11.5 via brew and reinstalled manually (same version), cleared the PATH variables to where export PATH="/Library/Frameworks/Python.framework/Versions/3.11/bin:$PATH" is the only entry, but now an error is getting thrown upon launch via python3.11 -m jupyter notebook that states a file being referenced is hidden or not a directory.

The file in question is a python alias that no longer functions properly--when clicked it returns a message saying The operation can’t be completed because the original item for “python” can’t be found.

Oddly enough, when re-naming the alias to "python-old" and creating a new alias called "python" that points to a functioning version, the below stack-trace references the "python-old" file as if even when re-named it is still link as THE version to reference.

Python3.11 works properly. Writing and running .py files from the IDLE works properly. Launching (and running) apache airflow from the command line and webserver interface works properly. For all intents and purposes, everything is working as intended--the only thing that is corrupt is this alias--which I can't recreate, re-name, or move.

Pretty perplexed here.

Full stack trace below. Good stuff is towards the bottom.

Although doing this manually had no effect, creating a simlink from /Users/name/python to /directory/for/requisite/version/of/python fixed the issue. Closing this out, as it was not a bug, rather user error.
