SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Pixi unifies conda-forge and PyPI dependency management, enabling reproducible environments for scientific Python projects and preventing drift between development and production.

Core Features & Use Cases

Unified Package Management: resolves dependencies from both conda-forge and PyPI in a single graph.
Multi-Platform Lockfiles: generate pixi.lock containing platform-specific specifications for Linux, macOS, and Windows.
pyproject.toml Integration: reads project metadata from pyproject.toml to align packaging workflows.
Task Automation: defines reusable tasks to automate install, test, and build workflows.

Quick Start

Create a new pixi project: pixi init --format pyproject
Add core dependencies: pixi add numpy scipy pandas
Install and lock: pixi install

FAQPage Schema

How do I unify conda and PyPI dependencies in a single reproducible environment?▼

To unify conda and PyPI dependencies for a reproducible environment, this Skill resolves packages from both sources into a single dependency graph. It enforces deterministic workflows by generating a single cross-platform lockfile within your pyproject.toml configuration.

How do I generate a cross-platform lockfile for Linux, macOS, and Windows using pyproject.toml?▼

Generating a cross-platform lockfile for Linux, macOS, and Windows is achieved by resolving dependencies within a pyproject.toml configuration. The process creates a pixi.lock file containing platform-specific specifications to ensure deterministic installations across operating systems.

What is the best way to manage multi-platform scientific Python projects with conda-forge and PyPI?▼

The best way to manage multi-platform scientific Python projects with conda-forge and PyPI is by unifying their dependency graphs within a pyproject.toml configuration. This approach prevents drift between development and production by enforcing a single cross-platform lockfile.

Can I automate install, test, and build tasks within a unified conda and PyPI workflow?▼

You can automate install, test, and build tasks within a unified conda and PyPI workflow by defining reusable task-based commands. This task automation integrates directly with the pyproject.toml configuration to execute deterministic workflows across platforms.

Does this dependency management approach support multi-platform projects without separate lockfiles?▼

This dependency management approach supports multi-platform projects by enforcing a single cross-platform lockfile. Instead of maintaining separate lockfiles, it generates a unified pixi.lock containing platform-specific specifications for Linux, macOS, and Windows.

Why does my scientific Python environment drift between development and production?▼

Scientific Python environments drift between development and production due to unresolved dependency conflicts across conda-forge and PyPI. Unifying these dependency graphs and enforcing a cross-platform lockfile prevents this drift and ensures reproducible environments.
