VS Code error: pre-commit not found. Did you forget to activate your virtualenv?

from that output it appears you ran pre-commit install using the thermo environment (which may not exist any more?) could you try re-running pre-commit install and seeing if the issue persists?

if you’re on macos, I’d generally suggest brew install pre-commit over using conda

my guess (you haven’t provided enough information) is you’re using conda on windows – there’s a known issue with conda’s packaging there: https://github.com/conda-forge/pre-commit-feedstock/issues/9
