Robots, but make it messy
Pixi: Reproducible Package Management for Robotics
Escape the Ubuntu handcuffs? Half the crowd yells “Debian”, the rest cheer Pixi
TLDR: Pixi promises easy, repeatable robot software setups on Mac, Windows, and Linux without Docker or Ubuntu lock-in. Comments split: Debian-or-bust skeptics, cautious devs who fear owning builds, and fans calling Pixi a sleeper hit—because consistent robot setups across computers matter.
Robots, but without the ritual Ubuntu setup? That’s the promise of Pixi, a new tool aiming to make ROS (Robot Operating System) installs repeatable across Mac, Windows, and Linux—no Docker, no distro drama. But the community immediately split into camps, and the comments were the main event. One critic lit the fuse with a savage line about ROS being a stack of “layers” on layers, insisting the real fix is to put everything in Debian (the classic Linux distro). Cue eye-rolls and applause—depending on which tribe you’re in. The cautious crowd was intrigued but wary: sure, easier installs on non‑Ubuntu sounds great, but nobody wants to babysit slow build systems or maintain the plumbing. The practical win everyone noticed: running old and new ROS side‑by‑side to help teams migrate without wrecking their setup. Meanwhile, fans came ready with heart emojis: “people have been sleeping on Pixi,” one wrote, saying it finally smoothed out niche workflows that other tools fumble. A wholesome curveball: someone asked if there’s a simulator so you can learn without owning a robot—relatable and very on‑brand for a community tired of hardware gatekeeping. Verdict? Pixi’s pitch is clean, but the comments prove the culture war isn’t over—Debian die‑hards vs. cross‑platform dreamers, fight!
Key Points
- •Pixi is a Conda-based package manager enabling reproducible, cross-platform ROS environments without Docker or Ubuntu dependence.
- •It addresses ROS challenges including Ubuntu lock-in, distribution coupling, global installs, multi-distro maintenance, and Docker overhead.
- •Pixi supports installing ROS on Linux, macOS, and Windows, with isolated environments and automatic version pinning via a lockfile.
- •Teams can share setups using pixi.toml and use side-by-side ROS 1 and ROS 2 distributions on a single machine.
- •A quick start shows installing Pixi, adding the robostack-jazzy channel, installing ros-jazzy-ros-core, and running ROS 2 commands in a Pixi shell.
