Summary
Hello,
It seems that uv pip install --group and pip install --group (pip 25.1) have different behaviors for installing Dependency Groups.
[dependency-groups]
dev = [
"ruff",
]
$ uv pip install --group dev
warning: `.\scripts` does not appear to be a Python project, as the `pyproject.toml` does not include a `[build-system]` table, and neither `setup.py` nor `setup.cfg` are present in the directory
error: The dependency group 'dev' was not found in the project: pyproject.toml
$ pip install --group dev

Successfully installed ruff-0.11.7
As PEP 735 specifies that Dependency Groups support non-package projects and that the installation of a Dependency Group does not imply installation of a package's dependencies or the package itself, I believe that the behavior of pip is the expected behavior.
Thank you 🙏
