Reproducible example

Error:   × invalid bracket

Issue description

Pixi doesn't accept brackets

Expected behavior

work

[lucascolley]

pixi add --pypi "huggingface_hub[cli]"

If you aren't attached to getting your dependencies from https://pypi.org/, pixi add huggingface_hub may also work for you. https://prefix-dev.github.io/pixi/v0.50.1/concepts/conda_pypi/. Typically, conda packages automatically include the equivalent of extras when they are small, and are split into separate packages for substantial extras.

conda/ceps#111 for the interested reader :)

Forgot that brackets were a pypi thing, thanks for the reminder!
