Update environment python, installer, and other non-dependency params

[linjer]

I'm planning to upgrade a project's default Python version and installer from pip to uv, however, I can't get these changes synced to the environment like dependency changes do.

The hope is that I can perform this upgrade by updating the pyproject.toml file and all my teammates will have their environments updated, without me having to instruct them all to re-create their environments with something like hatch env remove && hatch env create.

I have tried entering the environment with hatch -e myenv shell, running python scripts in the environment via hatch run myscript, and updating the dependencies. None of these activities result in the changed python and uv parameters being recognized.

Is there a way to get hatch to update the environment without having all my teammates manually re-create their envs?

Can you please explain what exactly didn't work when you switched the installer to UV?

When I have an existing environment that was created with installer = "pip", then I change to installer = "uv" and update a dependency, when I try doing something like hatch -v run python --version to trigger dependency sync, pip is still being used. I have to completely re-create the environment for uv to begin managing dependencies.

Here are the basic parameters I'm using for the environment:

[tool.hatch.envs.default]
python = "3.10"
type = "virtual"
path = ".venv"
# installer = "pip"
installer = "uv"
