How to install fnm

Fnm is developer utility. This page carries no procedure of its own; it records what the project is and what to look at before touching it.

Paths onto a machine

In practice this means one of a handful of routes: an operating system package index, a registry tied to a language, a version manager, or a source tree built with the project's own tooling. Which one applies is decided by the platform and by the maintainers.

Who is behind it

Ownership sits with the project's own contributors. Release cadence, supported platforms and documentation are all decided by them, and none of it is mediated here.

Prior checks

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.

Reading the outcome

Most unexpected behaviour traces back to resolution rather than to the project. An older copy sitting earlier in the path, or a version manager pointing somewhere else, will do it every time.

What this domain is

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

A note on older machines

Hardware age matters more than people expect here. Recent releases tend to assume modern runtimes and current system libraries, so an ageing machine can rule out the newest version entirely.
