Report #104328

[bug\_fix] yarn: The engine "node" is incompatible with this module. Expected version ">=14 <17". Got "18.0.0"

Update Node.js to a compatible version using nvm, or use \`yarn install --ignore-engines\` to bypass the check \(not recommended for production\).

Journey Context:
I was trying to set up an older project that required Node 14–16, but I had Node 18 installed. Yarn refused to install with an engine incompatibility error. I tried using \`--ignore-engines\` which worked but felt risky. I instead switched to Node 16 using \`nvm use 16\` and the install succeeded. The root cause: the package's \`engines\` field in package.json declares supported Node versions; yarn enforces this to prevent runtime issues. The fix aligns the Node version with the project's requirements.

environment: Node 18, yarn 1.22, macOS, legacy project · tags: yarn engine incompatible node-version · source: swarm · provenance: https://classic.yarnpkg.com/en/docs/cli/install\#toc-yarn-install-ignore-engines
