How to install ruby

Ruby is a dynamic language long associated with web work and developer ergonomics. This page carries no procedure of its own; it records what the project is and what to look at before touching it.

Distribution in practice

Expect differences between platforms. The same project may reach one system through a package index and another through a source build.

Who is behind it

Day-to-day direction belongs to the maintainers. They set the roadmap, cut releases, and decide which platforms stay supported.

First things to confirm

Establish which platforms the current release actually targets. Support ranges shift, and the newest release is frequently not the one suited to an older machine.

If something looks wrong

If the outcome is not what was expected, the cause is nearly always environmental: an earlier copy, a different channel, or a cache that has not been refreshed.

About these notes

This is a notes-only site. Projects stay with their maintainers; nothing is reproduced here.

On reading release notes

Release notes are the cheapest way to catch a breaking change before it surprises you. They usually list platform shifts and removed defaults in the first few lines.
