How to specify dependency groups with uv pip install and uv pip compile?

[cthoyt]

I'm on uv 0.5.4 (Homebrew 2024-11-20) and it doesn't appear there's a way to install dependency groups with uv pip install nor include it in compilation with uv pip compile.

Based on the PEP (cf. https://peps.python.org/pep-0735/#installing-dependency-groups), pip should eventually be able to do this with something like:

$ pip install --dependency-groups=tests .

I wasn't able to find any evidence that an implementation has made it into pip's recent October v24.3.1 release nor mention on its changelog (https://pip.pypa.io/en/stable/news/).

Q: Is uv waiting for pip to establish an interface, then it will adopt it? I can see how implementing something that is different from pip might be problematic for maintaining compatibility.

For context, uv sync already does implement dependency groups with --group and related flags.

Please see

• Lock dependency groups in the uv pip interface, i.e., uv pip compile --group #8969
• Install dependency groups in the uv pip interface, i.e., uv pip install --group #8590

We're waiting for an upstream implementation. I'm engaging a lot on the design.

sorry about that, I did in fact search the issue tracker, but didn't find those. Maybe you could also add the text "dependency group" / "dependency groups" without dashes to make it more findable!
