### What needs to get done This old experimental PR is an example: https://github.com/canonical/craft-parts/pull/825 You should be able to make parts like: ```yaml parts: python: source: . python-package-manager: uv poetry: source: . poetry-package-manager: uv ``` and instead of using the system `python -m venv` and installing pip in that virtual environment, it would use uv for the relevant `venv` and `pip` commands. ### Why it needs to get done The old methods are both slow and can be error-prone since the behaviour of `venv` and `pip` changes from base to base.
