I would like to support editable installs of a package and one of its dependencies, if the dependencies are already checked out locally.

This is what I tried:

[project]
name = "Test"
version = "0.1"
dependencies = [
    "humanize @ git+https://github.com/python-humanize/humanize.git/",
]

[tool.uv.sources]
humanize = { path = "../humanize", editable = true }

Unfortunately, uv pip install . gives me

  × Failed to build `test @ file:///C:/Git/bug`
  ├─▶ Failed to parse entry: `humanize`
  ╰─▶ Can't combine URLs from both `project.dependencies` and `tool.uv.sources`

I read some documentation, but I must admit I was unable to figure out if the above should be supported or not.

uv 0.5.6 (b70c4f30e 2024-12-03)
