Overview

# Astral UV

UV is an extremely fast Python package installer and resolver written in Rust.

Quick Reference

| Task | Command |

|------|---------|

| Create venv | uv venv |

| Install package | uv pip install |

| Add dependency | uv add |

| Run script | uv run |

| Sync dependencies | uv sync |

| Init project | uv init |

Project Management

Initialize a new project:

```bash

uv init my-project

cd my-project

```

Add dependencies (updates pyproject.toml automatically):

```bash

uv add requests httpx

uv add --dev pytest ruff

```

Sync environment with lockfile:

```bash

uv sync

```

Running Code

Run scripts without manual venv activation:

```bash

uv run python script.py

uv run pytest

uv run ruff check .

```

Run with inline dependencies:

```bash

uv run --with requests script.py

```

Virtual Environments

```bash

uv venv # Create .venv

uv venv --python 3.12 # Specific Python version

```

pip Interface

Drop-in pip replacement (10-100x faster):

```bash

uv pip install requests

uv pip install -r requirements.txt

uv pip compile requirements.in -o requirements.txt

```

Python Version Management

```bash

uv python install 3.12 # Install Python version

uv python list # Show available versions

uv python pin 3.12 # Pin version for project

```

Best Practices

Prefer uv add over uv pip install for project dependencies
Use uv run instead of activating venvs manually
Commit uv.lock to version control
Use uv sync --frozen in CI for reproducible builds
Add dev dependencies with uv add --dev
