This library can use any version of Python 3.11, which you can install alongside your existing 3.10.9 without changing your global python version. I don't typically work in Windows so the codeblock below is AI generated, but follows the path I would normally take - manage installed python versions using pyenv, changing the python version only for this directory via .python_version, and then creating uv environment using that.

``` :: Step 1: Install pyenv-win (make sure Git is installed) git clone https://github.com/pyenv-win/pyenv-win.git "$env:USERPROFILE\.pyenv"

:: Step 2: Add pyenv to PATH (run or add to your profile) $env:PYENV = "$env:USERPROFILE\.pyenv\pyenv-win" $env:PATH += ";$env:PYENV\bin;$env:PYENV\shims"

:: Step 3: Restart your terminal or reload environment if needed :: (you can paste the above $env:... lines again after restart)

:: Step 4: Install Python 3.11 pyenv install 3.11.9

:: Step 5: Set the local Python version for your project folder cd C:\devel\us-routing-master\us_routing pyenv local 3.11.9

:: Step 6: Verify correct Python is selected pyenv which python # should point to 3.11.x

:: Step 7: Create uv environment using Python 3.11 uv venv .venv --python "$(pyenv which python)"

:: Step 8: Activate the environment .venv\Scripts\activate

:: Step 9: Install your package uv pip install us-routing ```

pyenv is a great way to have many versions of Python installed, whether or not your global is mapped to the latest. You don't even need to set the local .python_version.. you could just do `uv venv .venv --python=python3.11`
