Managing `julia` versions using `pixi`

I even tried removing these files:

$ rm -rf .pixi/envs/default/build_env.sh 
$ rm -rf .pixi/envs/default/conda-meta 
$ rm -rf .pixi/envs/default/conda_build.sh

I don’t know exactly how pixi works, but these were the only files that had a lot of environment variables, and thought I’d try to delete them. But I still get an error:

╭─ ~/g/pixi-test 
╰ rm -rf .pixi/envs/default/build_env.sh .pixi/envs/default/conda-meta .pixi/envs/default/conda_build.sh

╭─ ~/g/pixi-test
