I have a Python package (quacc) that has a required dependency (ase). The most recent version of ase on PyPI is 3.22.1, but the master branch of ase is >3.22.1. Since the quacc package relies on features added since the last ase release, in the dependencies list in pyproject.toml of my quacc package, I have ase>3.22.1 to ensure that users won't have a silent failure when installing the package if they have an out-of-date dependency. However, uv does not like this at all (even though pip is perfectly content).

Reproduction with uv 0.1.13 on Ubuntu in a clean miniconda environment:

uv pip install "ase @ git+https://gitlab.com/ase/ase.git" # installs >3.22.1
uv pip install "quacc @ git+https://github.com/Quantum-Accelerators/quacc.git" # or `uv pip install quacc`

Traceback:

 Updated https://github.com/Quantum-Accelerators/quacc.git (8c55f09)                     × No solution found when resolving dependencies:
  ╰─▶ Because only ase<=3.22.1 is available and quacc==0.6.8 depends on ase>3.22.1,
      we can conclude that quacc==0.6.8 cannot be used.
      And because only quacc==0.6.8 is available and you require quacc, we can
      conclude that the requirements are unsatisfiable.

While it is true that only ase<=3.22.1 is available on PyPI, the current Python environment has ase>3.22.1, and that should have priority. uv should not try to be installing ase since it's already in my environment.
