Managing Dependencies with UV and Pip¶

Using UV¶

UV is a fast Python package manager for efficient dependency management.

Installation¶

To install UV, run the following command:

pip install uv

Installing Dependencies¶

To install project dependencies in editable mode, use:

uv pip install --editable ".[dev]"

Development Tools¶

Use UV to run various development tools:

uvx ruff format py_launch_blueprint/       # Format code  
uvx ruff check py_launch_blueprint/        # Run linter  
uvx --with-editable . mypy py_launch_blueprint/  # Type check  
uvx --with-editable . pytest               # Run tests  
uvx --with pytest-cov --with-editable . pytest --cov=py_launch_blueprint.projects --cov-report=term-missing  # Test coverage  

Pre-Commit Hooks (Optional)¶

Set up and run pre-commit hooks with:

uvx --with-editable . pre-commit install  
uvx pre-commit run --all-files  

Updating & Removing Packages¶

To update all dependencies, use:

uv pip install --upgrade                    # Update all dependencies  
uv pip install --upgrade <package-name>     # Update a specific package  
uv pip uninstall <package-name>             # Remove a package  

Freezing Dependencies¶

To freeze the dependencies into a requirements.lock file:

uv pip freeze > requirements.lock

Using Pip¶

Virtual Environment Setup¶

To create and activate a virtual environment:

python3 -m venv .venv  
source .venv/bin/activate   # Unix/macOS  
.venv\Scripts\activate      # Windows  

Installing Dependencies¶

Install project dependencies in editable mode:

pip install --editable ".[dev]"

Running Tools¶

You can run development tools directly with pip:

ruff format py_launch_blueprint/  
ruff check py_launch_blueprint/  
mypy py_launch_blueprint/  
pytest --cov=py_launch_blueprint.projects --cov-report=term-missing
