Setup and Share Python Environment Using Pixi

How to Set Up and Share a Python Environment Using Pixi

Goal

Set up a reproducible Python environment using Pixi and share it with others via pixi.toml and pixi.lock.

Step 1: Install Pixi

1. Go to the official Pixi installation page.
2. On Windows, run:

winget install prefix-dev.pixi

3. Verify installation:

pixi --version

Step 2: Initialize a Pixi Environment

pixi init

This command creates a pixi.toml file in the current directory.

Step 3: Add Python and pip

pixi add python pip

This installs Python and pip from the conda-forge ecosystem.

Step 4: Enter the Environment

pixi shell

You are now inside the managed environment.

Step 5: Add Packages

Example:

pixi add numpy matplotlib

Or from PyPI:

pixi add --pypi streamlit

Step 6: Share the Environment

1. Commit or send the pixi.toml and pixi.lock files.
2. Others can recreate the same environment by running:

pixi install

Summary

You have successfully created and shared a Python environment using Pixi.
