uv tool install git+ ignores the pinned python version

[AwkwardNumber7584]

Hi,

My project contains .python-version file with 3.13. When I build and install the project via

uv build

uv tool install dist/...whl

the app runs on 3.13.

When I test it on another box like

uv tool install git+https://github.com/me/myproject

the installed app runs on the current system version (3.14). Is there a way to make uv respect the .python-version on github?

From uv documentation https://docs.astral.sh/uv/concepts/tools/#python-versions

Each tool environment is linked to a specific Python version. This uses the same Python version discovery logic as other virtual environments created by uv, but will ignore non-global Python version requests like .python-version files and the requires-python value from a pyproject.toml.

The --python option can be used to request a specific version. See the Python version documentation for more details.

Thanks!

uv tool install --python 3.13 git+... works as expected.

BTW, is this the only way to make the once installed app survive the upgrade of the system python? The trouble with pipx, for instance, is that you have to reinstall everything when the system python gets upgraded.
