poetry returns 'dyld: Library not loaded ... image not found' following brew install while inside virtual environment

Question

I ran brew install postgresql while inside a poetry environment. Since then, I can't interact with poetry.

λ ~/ poetry
dyld: Library not loaded: /usr/local/Cellar/[email protected]/3.9.9/Frameworks/Python.framework/Versions/3.9/Python
  Referenced from: /Users/<my username>/Library/Application Support/pypoetry/venv/bin/python
  Reason: image not found
[1]    5634 abort      poetry

I get the same output when I try poetry <any other command>. I tried removing my virtual environments from λ ~/Library/Caches/pypoetry/virtualenvs/ expecting to be able to reinstall them from the .toml files in my projects, but can't run poetry install because I receive the same error.

I am running MacOS 10.15.7, Homebrew 3.3.12, poetry 1.1.12, & pyenv 2.2.4.

I'm resolving this in case someone runs into the same issue.

Uninstalling and reinstalling poetry fixed the problem. I wasn't able to do this with the --uninstall option and instead had to do it manually. I first ran rm -rf pypoetry inside ~/Library/Application Support/. Then I re-ran the install line from poetry's site: curl -sSL https://install.python-poetry.org | python3 -.

The cause of the issue was using poetry shell instead of just poetry run jupyterlab –– this opened me up to absent-mindedly screwing up the poetry install by running brew installs while in the shell. Lesson learned!
