Packages with git-based sources are not installed correctly

[tpanum]

Issue

When I add a package with uv add git+https://github.com/owner/pkgname.git, it is installed just as pkgname (without a specifier) and ignores its location.

Environment

Provide at least:

• OS: MacOS

Minimal example

uv add git+https://github.com/scikit-learn-contrib/skglm.git
uvx --with tox-uv tox -r run

Causes the following uv pip install:

uv pip install skglm

I would be expecting:

uv pip install git+https://github.com/scikit-learn-contrib/skglm.git

I am having a related issue as I am using uv workspaces.

In general, it seems that uv pip will ignore anything in [tool.uv.sources] (see astral-sh/uv#8846). As a result, tox-uv which relies on uv pip install in its install command will fail. Any recommendation for a workaround?

@tpanum I may have a workaround that would work in your case. Try go to your pyproject.toml and include your git-based dependency that way:

[project]
...
dependencies = [
  ...
  "pkgname@git+https://github.com/owner/pkgname.git"
 ]
 ...

This should be installable using uv pip install, so tox run should work.

Just an update. This issue also apply to file-based sources, e.g. uv add ../my-pkg will fail as it tries to install using uv pip install my-pkg.

I feel the install command should not rely on uv pip but on uv sync. However, I have not been able to make it work.

Any help is appreciated!

Thanks for pointing me in the direction of tox-uv using uv pip by default. I honestly didn't pay too much at that at first.

Knowing that, and following the README.md, it is very apparant that using the uv-venv-lock-runner is the way forward for my issues.

I ended up with the following tox.ini which hopefully can help people with similar problems.

[tox]
envlist = py311

[testenv]
runner = uv-venv-lock-runner
uv_sync_flags=--python={env_python}, --no-editable
with_dev =
    true
commands =
    python -m pytest -s {posargs}

Just a small note, the --python={env_python} is just a measure to fix some issues described in #110.
