@jcgraciosa I recently encountered this bug as well. I tried installing the xxhash package within the pixi environment, but it still wasn’t recognised. In the end, I had to remove the pixi environment and reinstall it from scratch to resolve the issue.

Could you please update the toml file with the fix and open a PR? I’ll also test the fix on my side to confirm that it works.
