Project lifecycle management 🔄

uv publish Publish your packageable project to PyPI
uv version Check your project version
uv version --bump major Bump project major version (e.g., 0.3.2 -> 1.0.0)
uv version --bump minor --bump beta Bump minor version into a beta (e.g., 1.0.0 -> 1.1.0b1 or 1.1.0b1 -> 1.1.0b2)
uv version --bump rc Bump version into release candidate (e.g., 1.1.0b1 -> 1.1.0rc1 or 1.1.0rc1 -> 1.1.0rc2)
uv version --bump stable Turn into a stable version (e.g., 1.1.0rc1 -> 1.1.0)

Managing tools ⚒️
uv tool run pytest Run pytest in an isolated environment
uv tool run textual-demo --from textual Run the command textual-demo from the package textual
uvx ... Alias for uv tool run ...
uv tool install ruff Install ruff in an isolated environment but make it globally available
uv tool install --with dep ... Install the given tool with extra dependencies (e.g., install a tool with its plugins)
uv tool list List all tools installed
uv tool upgrade ruff Upgrade the ruff tool
uv tool upgrade --all Upgrade all tools
uv tool uninstall ruff Uninstall ruff
uv tool install -e .2 Install the current packageable project in editable mode

Working with scripts 📜
uv init --script myscript.py Initialise the script myscript.py
uv init --script myscript.py --python 3.X Initialise the script myscript.py and pin it to version 3.X
uv add click --script myscript.py Add the dependency click to the script
uv remove click --script myscript.py Remove the dependency click from the script
uv run myscript.py Run the script myscript.py
uv run --python 3.X myscript.py Run the script with the given Python version
uv run --with click myscript.py Run the script along with the click dependency

Make your script executable and add the uv shebang at the very first line of the script: #!/usr/bin/env -S uv run. This way, you can run your script directly as ./myscript.py instead of having to write uv run myscript.py.

uv python install 3.X Install Python 3.X
uv python uninstall 3.X Uninstall Python 3.X

  1. The --python 3.X option is transversal to almost everything in uv. ↩

  2. If your project provides a CLI, for example, this makes the CLI globally available on your computer. Making it editable with -e means that if you update your code, you don't have to reinstall explicitly. ↩
