UV Package Manager

UV is a fast Python package manager that provides efficient dependency management. This guide covers how to set up and use UV in the Py Launch Blueprint project.

Installation

To install UV, run:

pip install uv

Alternatively, this project’s root Makefile provides convenient targets for installing and force-installing uv:

make install-uv
make install-uv-force

Refer to the Makefiles documentation for more details on these make commands, especially if you prefer a project-standardized installation method or encounter issues with other methods.

Using UV for Dependency Management

Installing Dependencies

To install dependencies from pyproject.toml, use:

uv pip install -r requirements.txt

Or, if using pyproject.toml:

uv pip install

Adding a Package

To install a package and add it to your dependencies:

uv pip install <package-name>

Removing a Package

To uninstall a package:

uv pip uninstall <package-name>

Creating a Lockfile

To generate a lockfile (requirements.lock), run:

uv pip freeze > requirements.lock
