Reading time: 2 minutes

uv is a Rust-based Python installer and resolver designed to replace β€œpipβ€œ, β€œpip-toolsβ€œ, and β€œvirtualenv” commands, offering great 10-100x speed and advanced features like dependency version overrides and alternative resolution strategies.

It has already been tested at scale against the top 10,000 PyPI packages, supporting global cache for dependency deduplication, indirectly saving disk space, and offering best-in-class error messages with a conflict-tracking resolver.

I must definitely recommend you give it a try by reading this article, learning the installation steps, and a usage guide with practical examples.

How to Install uv on Linux, Windows, and macOS

The best thing about this tool is its availability for installation via Pip and Pipx. However, I would recommend installing it using the curl command in Linux, the irm command in Windows, and the brew command in macOS.

uv itself doesn’t depend on Python but requires a Python environment for installing dependencies and setup; thus, ensure Python is installed on your system.
#For Linux and macOS.
$ curl -LsSf | sh

#For Windows.
$ irm | iex

#With Homebrew.
$ brew install uv

#With Pip.
$ pip install uv

#With Pipx.
$ pipx install uv

Once the installation is complete, make sure to restart your terminal session to apply the change, then run the following command to verify that it’s successfully installed and accessible via the terminal.

$ uv --version

How to Use uv to Manage Python Packages

uv can be used in numerous ways to manage your Python packages, such as creating a virtual environment with uv, run.

$ uv venv


creating virtual environment with uv

Once created to activate the virtual environment, run.

#On Linux and macOS
$ source .venv/bin/activate

#On Windows
$ .\.venv\Scripts\activate.ps1


activating the python virtual env

To install a package inside the virtual environment, you can run one of the following commands based on the situation.

#Install a single package (in this case, Flask).
$ uv pip install flask

#Install multiple packages from a "requirements.txt" file.
$ uv pip install -r requirements.txt

#Install the current project in editable mode.
$ uv pip install -e .

#Install the current project from disk.
$ uv pip install "package @ ."

Furthermore, you can use the rest of the β€œpipβ€œ, β€œpip-toolsβ€œ, and β€œvirtualenv” commands with uv by prefixing β€œuv” before each of these commands at the time of execution.

I’ll end this article here; you can dig deeper from the project page and note that certain Pip features, like β€œ.egg” dependencies, editable installs for Git, and direct URL dependencies, are not supported.

If encountering any issues, raise a new request on the project issues page; additionally, consider checking out the release page to stay informed on the latest uv releases, which frequently introduce new features, bug fixes, and more.
