Report #55611

[bug\_fix] npm WARN EBADENGINE Unsupported engine \{ package: 'X', required: \{ node: '>=18.0.0' \}, current: \{ node: '16.0.0' \} \}

Use nvm \(Linux/Mac\) or nvm-windows to switch to the required Node.js version \(nvm install 18 && nvm use 18\), or use --engine-strict=false to bypass \(not recommended for production\).

Journey Context:
Developer clones a modern project that specifies "engines": \{"node": ">=18.0.0"\} in package.json. They have Node 16 installed \(LTS from previous year\). Running npm install shows EBADENGINE warnings and may refuse to install with --engine-strict. They try --force which installs but native addons fail to compile against the wrong Node ABI. Realizing the project uses Node 18 features \(fetch API, native fetch\), they use nvm install 18 to get the correct version. This ensures engine compatibility and prevents runtime syntax errors or native module crashes.

environment: Projects with strict engines field in package.json, nvm/nvm-windows users, CI/CD with multiple Node versions · tags: npm engines ebadengine node-version nvm compatibility · source: swarm · provenance: https://docs.npmjs.com/cli/v8/configuring-npm/package-json\#engines
