see pavelzw/pixi-diff-to-markdown#66 for a reproducer.
pixi (and conda envs in general) stores its python site packages in .pixi/envs/<env-name>/lib/python3.13/site-packages (on windows). (note: this is the same environment that ty is installed in)
When running uv sync and afterwards pixi run ty check, I don't get the error anymore so it seems to me that ty is only checking .venv but not the actual environment that i'm using.
There are a lot of scenarios where it's not possible for me to use uv, for example in corporate settings where i only have a conda-forge mirror and not a pypi mirror, so ty supporting pixi environments would be very nice.
