How do I set up pre-commit for dev in a conda environment?

[chloeh13q]

I had trouble setting up the development environment via nix (not sure if it's because I have a MacBook with an M1 chip), so I set up everything in a conda environment instead. However, I had problems with a few pre-commit hooks, most notably ruff, with the following error:

ruff.....................................................................Failed
- hook id: ruff
- exit code: 2

error: TOML parse error at line 389, column 3
    |
389 |   "FA",  # flake8-future-annotations
    |   ^^^^
Unknown rule selector `A`

@deepyaman gets something similar in his dev environment:

ruff.....................................................................Failed
- hook id: ruff
- exit code: 2

error: TOML parse error at line 431, column 3
    |
431 |   "PLC0105", # covariant type parameters should have a _co suffix
    |   ^^^^^^^^^
Unknown rule selector: `PLC0105`

Has anyone successfully set up all the pre-commit hooks for Ibis in a conda environment?

You'll see those kind of errors when your version of ruff is too old. Two things that could cause this:

• You may just need to update your conda environment with recently generated lockfiles.
• If you're using the latest conda-lock files then the issue is that those can be a bit out of date. The conda-lock files aren't always in sync with the poetry.lock file, they're batch updated periodically, not every time the poetry deps are updated.

Pragmatic honest answer: when I run into this issue I just run pip install -U ruff and things work again :). Note as pure as using a lockfile, but it lets me get things working and get back to work.

pip install -U ruff solved the problem. Thanks for the fast response!
