Edit: thanks very much for the suggestions, especially adding the Python version to the uv command line. I totally missed that, and that totally fixed it. Apologies for the OT tech support derailment.

Question for those familiar with uv. US Routing apparently requires a very specific Python version (3.11 and nothing else), but my system has Python 3.10.9 installed at the moment and I'd rather not upgrade the global version just now. My understanding from reading a lot of uv evangelism on HN and elsewhere is that uv fixes this type of dilemma. But, having just tried to use it to install this package, it's just giving me the same old Python version errors:

    C:\devel\us-routing-master\us_routing>uv venv
    Using CPython 3.10.9 interpreter at: c:\WinPython-31090
    \python-3.10.9.amd64\python.exe
    Creating virtual environment at: .venv
    Activate with: .venv\Scripts\activate

    C:\devel\us-routing-master\us_routing>.venv\Scripts\activate

    (us_routing) C:\devel\us-routing-master\us_routing>uv pip     
    install us-routing

    x No solution found when resolving dependencies:
    `-> Because the current Python version (3.10.9) does not 
    satisfy Python>=3.11,<3.12 and us-routing==0.1.0
    depends on Python>=3.11,<3.12, we can conclude that us-    
    routing==0.1.0 cannot be used.
    And because only us-routing==0.1.0 is available and you 
    require us-routing, we can conclude that your
    requirements are unsatisfiable.

Am I misunderstanding the whole uv thing, or just doing something wrong? Or is us-routing somehow incompatible with it?
