Issue

Hello. I am trying to use Poetry for mac with Python 3.10. It was working before but I re-installed both Python and poetry and I can’t seem to get it to work. I can run commands like poetry --version but commands such as poetry install poetry lock poetry show all faill with [Errno 2] No such file or directory: 'python' and the above stack trace on debug mode.

I have tried installing Poetry both with curl -sSL https://install.python-poetry.org | python3 - as well as the manual way with pip3 install poetry. My Python is installed via the regular Python.org .pkg installer for MacOS but I had it installed with homebrew before which also suffered from the same issue.

Thank you in advance for the help!
