pixi: Package Management Made Easy Overview

pixi is a cross-platform, multi-language package manager and workflow tool built on the foundation of the conda ecosystem. It provides developers with an exceptional experience similar to popular package managers like cargo or yarn, but for any language.

Developed with ❤️ at prefix.dev. Real-time pixi_demo

Highlights Supports multiple languages including Python, C++, and R using Conda packages. You can find available packages on prefix.dev. Compatible with all major operating systems: Linux, Windows, macOS (including Apple Silicon). Always includes an up-to-date lock file. Provides a clean and simple Cargo-like command-line interface. Allows you to install tools per-project or system-wide. Entirely written in Rust and built on top of the rattler library. Getting Started ⚡ Installation ⚙️ Examples 📚 Documentation 😍 Contributing 🔨 Built using Pixi 🚀 GitHub Action Status

Pixi is ready for production! We are working hard to keep file-format changes compatible with the previous versions so that you can rely on pixi with peace of mind.

Some notable features we envision for upcoming releases are:

Build and publish your project as a Conda package. Support for dependencies from source. More powerful "global installation" of packages towards a deterministic setup of global packages on multiple machines. Installation

pixi can be installed on macOS, Linux, and Windows. The provided scripts will automatically download the latest version of pixi, extract it, and move the pixi binary to ~/.pixi/bin. If this directory does not exist, the script will create it.

macOS and Linux

To install Pixi on macOS and Linux, open a terminal and run the following command:

curl -fsSL https://pixi.sh/install.sh | bash # or with brew brew install pixi

The script will also update your ~/.bash_profile to include ~/.pixi/bin in your PATH, allowing you to invoke the pixi command from anywhere. You might need to restart your terminal or source your shell for the changes to take effect.

Starting with macOS Catalina zsh is the default login shell and interactive shell. Therefore, you might want to use zsh instead of bash in the install command:

curl -fsSL https://pixi.sh/install.sh | zsh

The script will also update your ~/.zshrc to include ~/.pixi/bin in your PATH, allowing you to invoke the pixi command from anywhere.

Windows

To install Pixi on Windows, open a PowerShell terminal (you may need to run it as an administrator) and run the following command:

iwr -useb https://pixi.sh/install.ps1 | iex

The script will inform you once the installation is successful and add the ~/.pixi/bin directory to your PATH, which will allow you to run the pixi command from any location. Or with winget

winget install prefix-dev.pixi Autocompletion

To get autocompletion run:

# On unix (MacOS or Linux), pick your shell (use `echo $SHELL` to find the shell you are using.): echo 'eval "$(pixi completion --shell bash)"' >> ~/.bashrc echo 'eval "$(pixi completion --shell zsh)"' >> ~/.zshrc echo 'pixi completion --shell fish | source' >> ~/.config/fish/config.fish echo 'eval (pixi completion --shell elvish | slurp)' >> ~/.elvish/rc.elv

For PowerShell on Windows, run the following command and then restart the shell or source the shell config file:

Add-Content -Path $PROFILE -Value '(& pixi completion --shell powershell) | Out-String | Invoke-Expression'

And then restart the shell or source the shell config file.

Distro Packages

Packaging status

Arch Linux

You can install pixi from the extra repository using pacman:

pacman -S pixi Alpine Linux

pixi is available for Alpine Edge. It can be installed via apk after enabling the testing repository.

apk add pixi Build/install from source

pixi is 100% written in Rust and therefore it can be installed, built and tested with cargo. To start using pixi from a source build run:

cargo install --locked --git https://github.com/prefix-dev/pixi.git pixi

We don't publish to crates.io anymore, so you need to install it from the repository. The reason for this is that we depend on some unpublished crates which disallows us to publish to crates.io.

or when you want to make changes use:

cargo build cargo test

If you have any issues building because of the dependency on rattler checkout it's compile steps

Uninstall

To uninstall the pixi binary should be removed. Delete pixi from the $PIXI_DIR which is default to ~/.pixi/bin/pixi

So on Linux its:

rm ~/.pixi/bin/pixi

and on Windows:

$PIXI_BIN = "$Env:LocalAppData\pixi\bin\pixi"; Remove-Item -Path $PIXI_BIN

After this command you can still use the tools you installed with pixi. To remove these as well just remove the whole ~/.pixi directory and remove the directory from your path.

Usage

The cli looks as follows:

➜ pixi A package management and workflow tool Usage: pixi [OPTIONS] Commands: completion Generates a completion script for a shell init Creates a new project add Adds a dependency to the project run Runs task in project shell Start a shell in the pixi environment of the project global Global is the main entry point for the part of pixi that executes on the global(system) level auth Login to prefix.dev or anaconda.org servers to access private channels install Install all dependencies task Command management in project info Information about the system and project upload Upload a package to a prefix.dev channel search Search a package, output will list the latest version of package project help Print this message or the help of the given subcommand(s) Options: -v, --verbose... More output per occurrence -q, --quiet... Less output per occurrence --color Whether the log needs to be colored [default: auto] [possible values: always, never, auto] -h, --help Print help -V, --version Print version Creating a pixi project

Initialize a new project and navigate to the project directory

pixi init myproject cd myproject

Add the dependencies you want to use

pixi add cowpy

Run the installed package in its environment

pixi run cowpy "Thanks for using pixi"

Activate a shell in the environment

pixi shell cowpy "Thanks for using pixi" exit Installing a conda package globally

You can also globally install conda packages into their own environment. This behavior is similar to pipx or condax.

pixi global install cowpy Use in GitHub Actions

You can use pixi in GitHub Actions to install dependencies and run commands. It supports automatic caching of your environments.

- uses: prefix-dev/[email protected] - run: pixi run cowpy "Thanks for using pixi"

See the documentation for more details.
