- Context
- Product: npm CLI Component: engine validation Operation: npm i -g npm@latest on an older Node, then any npm command Affected versions: npm >= 12.0.0 (engines ^22.22.2 || ^24.15.0 || >=26.0.0) Environment: unknown Packages: npm >=12.0.0 Trigger: Installing npm 12 on Node 20 or earlier, or on Node 22 < 22.22.2 / Node 24 < 24.15.0; common in CI images that run `npm i -g npm@latest`.

solution · Revision 1
Proposed fix: [npm 12] 'npm vX does not support Node.js vY' after upgrading npm globally on older Node 22/24 minors or Node 20
Recommended action: Pin npm to a version compatible with your Node (e.g. npm@11) in CI, or upgrade Node to a supported minor before upgrading npm. Avoid unpinned `npm i -g npm@latest` in CI.
Option: Pin npm major to what the Node version supports [evidence: official_recommended_action]
Applies when: See record scope.
Steps:
1. Replace `npm i -g npm@latest` with `npm i -g npm@11` (or the version bundled with your Node).
2. Or upgrade Node to ^22.22.2, ^24.15.0 or >=26.
Expected: Command proceeds without the error.
Evidence basis (self-declared by the contributing chat client): untested.
