UV is Developed by Astral, the same team behind the popular linter Ruff, uv is a game-changer for Python developers. It's designed to be a drop-in replacement for your existing workflows, seamlessly integrating with common tools like pip, pip-tools, and virtualenv.

Why Choose uv?

uv boasts significant performance improvements over traditional methods, achieving a remarkable 10-100x speed boost. This translates into:

• Faster package installation: No more waiting around for your packages to install, making your development process significantly smoother.

• Efficient dependency resolution: uv tackles complex dependency chains with lightning speed, reducing frustrating wait times and potential errors.

• Improved developer productivity: Spend less time managing dependencies and more time coding, driving your projects forward.

Installation: Getting Started with uv

Getting uv up and running is incredibly easy. Since it's a cross-platform tool, you can install it on Linux, Windows, and macOS. The recommended approach is to use the official installation script, which handles everything for you.

Linux and macOS:

curl -LsSf https://astral.sh/uv/install.sh | sh
    

Windows:

Alternatively, if you prefer using pip or pipx, you can install uv with the following commands:

pip install uv
OR
pipx install uv
    

Note: While uv itself is not dependent on Python, it requires a Python environment to install its dependencies. Make sure you have Python installed on your system before proceeding.

Using the uv Command

Once uv is installed, you can access its features through the uv command. To see the available options, simply run:

      uv
    

This will display a comprehensive help section, outlining all the commands and features offered by uv.

Extending Existing Commands: A Powerful Feature

One of the key strengths of uv is its ability to enhance and extend existing commands like venv.

Creating and Activating Virtual Environments:

To create a virtual environment using uv, simply prefix the venv command with uv:

      uv venv
    

Activating the virtual environment is straightforward:

Linux and macOS:

      source .venv/bin/activate
    

Windows:

      .\.venv\Scripts\activate.ps1
    

Installing Packages with uv:

Inside your virtual environment, uv provides a unified interface for installing packages:

• Installing a single package:

      uv pip install flask
    

• Installing multiple packages from a requirements.txt file:

      uv pip install -r requirements.txt
    

Installing the current project in editable mode:

      uv pip install -e .
    

• Installing the current project from the disk:

      uv pip install "package @ ."
    

mportant Note: While uv supports most common pip features, it doesn't yet handle .egg dependencies, editable installs for Git, or direct URL dependencies.
