# Uv Package Manager

> Master the uv package manager for fast Python dependency management, virtual environments, and…

A complete working guide to uv, the Rust-built Python package manager that resolves and installs dependencies 10-100x faster than pip. It covers virtual environments, lockfiles, Python version management, and migration from pip, Poetry, and pip-tools so your Python projects become fast, reproducible, and CI-friendly.

## Use cases
- Setting up new Python projects with uv init
- Replacing slow pip/Poetry dependency installs
- Reproducible builds with uv.lock and uv sync --frozen
- Speeding up CI/CD pipelines with global cache
- Optimizing Docker builds with multi-stage venv copies
- Migrating monorepos with workspace members

## Benefits
- Cut dependency install and CI time dramatically
- Get deterministic, reproducible builds across every environment
- Run tools and scripts without manually activating virtualenvs
- Migrate from pip, Poetry, or pip-tools incrementally with a rollback path

## What’s included
- Virtual environment, uv run, and Python version pinning patterns
- Lockfile workflows including frozen installs and requirements.txt export
- CI/CD GitHub Actions and multi-stage Docker integration examples
- Monorepo workspace configuration
- Side-by-side speed comparisons against pip, Poetry, and pip-tools
- Migration guides plus a troubleshooting and best-practices reference

## Who it’s for
Python developers and DevOps engineers who want faster, reproducible dependency management and quicker CI pipelines.

## How it runs
The 10-100x speedup over pip comes from a global cache and a frozen lockfile path, not magic. From uv init to CI and Docker, the workflow runs end to end:
1. Initializes the project with uv init and immediately pins the interpreter with uv python pin, writing .python-version so every machine resolves the same Python.
2. Adds dependencies with explicit constraints (uv add "django>=4.0,<5.0") and keeps dev packages strictly separated via uv add --dev, so test tooling never inflates the production image or its attack surface.
3. Locks the tree with uv lock and commits uv.lock; upgrades are explicit and surgical (uv lock --upgrade-package for one package, --upgrade for all), and conflicts are diagnosed with uv lock --verbose and uv tree.
4. Runs everything through uv run without manual venv activation; the global cache means a package downloaded once is reused across every project on the machine, which is where the 10-100x speed over pip comes from.
5. Wires CI and Docker on the frozen path: uv sync --frozen skips resolution and installs exact lockfile versions, setup-uv with enable-cache shares the cache across runners, and multi-stage Docker builds copy the venv into a runtime image that needs no uv binary.
6. Migrates incrementally from pip, poetry or pip-tools: imports requirements.txt with uv add -r, keeps a backward-compatible export running in parallel during the transition, and retires the old tool only after both produce identical results.

## FAQ
### Our projects are deep in Poetry and pip-tools, can we migrate without a big-bang rewrite?
Yes, the migration guides are incremental with a rollback path, and uv can export to requirements.txt so downstream tooling keeps working during the transition. You can move one repo or one workspace member at a time.

### Is the 10-100x speed claim real, and where does it come from?
It comes from uv's Rust resolver and a global cache that skips re-downloading and re-building across projects. The skill includes side-by-side comparisons against pip, Poetry, and pip-tools plus the CI and multi-stage Docker patterns where the cache pays off most.

### Does it replace conda for non-Python native packages?
No. uv manages Python dependencies, virtual environments, lockfiles, and Python interpreters. If your stack depends on conda-distributed native libraries outside PyPI, that part of the toolchain stays where it is.
