Regression in uv 5.10 installing from directory/git package with pyproject.toml

[peterroelants]

uv pip install a directory with a pyproject.toml fails with uv version 0.5.10 (and works with uv<0.5.10)

❯ uv pip install <package-name> @ git+ssh://git@<package_github_url>

        | ^^^^^^^^^
      `pyproject.toml` is using the `[project]` table, but the required `project.version` field is neither set nor present in the `project.dynamic` list

pyproject.toml looks like:

[project]
name = "<package-name>"
description = "Package discription"
version = "0.0.1"
readme = "README.md"
license = {text = "Proprietary/Confidential"}
classifiers = [
    "Programming Language :: Python :: 3",
]
requires-python = ">=3.9"
dynamic = [
  "dependencies",
]

[build-system]
requires = ["setuptools>=67", "wheel", "pip"]
build-backend = "setuptools.build_meta"

[tool.setuptools.dynamic]
dependencies = {file = ["env/requirements.txt"]}

[tool.setuptools.packages.find]
where = ["./src"]

[project.urls]
source = "<package_github_url>"

I can successfully install the package with uv-0.5.9 using uv pip install <package-name> @ git+ssh://git@<package_github_url>.

Please provide a Git repo that I can clone to reproduce.

I'm sorry for not providing an MRE initially, I was having the issue with a private repo that I couldn't share.

However, I've been able to replicate it in the meantime at https://github.com/peterroelants/test_uv_pyproject_toml . The issue is a bit more complicated as I originally thought, more details are in the README of that repo

You can test it running:

uv pip install "test-uv-pyproject-toml @ git+ssh://[email protected]/peterroelants/test_uv_pyproject_toml.git#subdirectory=projects/subproject"

Using uv=0.5.10.

I'm not sure if it's an actual issue, but is definitely a regression (works with uv 0.5.9) and the behavior differs from pip, which also works fine.
