Report #48279

[bug\_fix] npm WARN EBADENGINE Unsupported engine \{ package: 'some-pkg', required: \{ node: '>=18.0.0' \}, current: \{ node: '16.14.0' \} \}

Upgrade Node.js to the required version using nvm install 18 \(or nvm use 18\), or adjust the project to use an older compatible version of the package.

Journey Context:
Developer clones a modern repository or updates dependencies. Running npm install produces EBADENGINE warnings or errors \(if engine-strict is true\). The package requires Node 18\+, but the developer is on Node 16 \(LTS maintenance\). Developer considers using --force to bypass, but realizes this only suppresses the warning; the package may use native Node 18 APIs \(like fetch\) that will crash at runtime. Checking the package.json engines field confirms the requirement. Developer uses nvm to install and switch to Node 18 \(LTS\), updates .nvmrc for the team, reinstalls node\_modules. The warning disappears and the application functions correctly.

environment: Projects using modern Node.js features \(fetch API, native test runner, structuredClone\), CI/CD with pinned Node versions, monorepos with mixed engine requirements · tags: npm ebadengine engine-strict node-version nvm compatibility · source: swarm · provenance: https://docs.npmjs.com/cli/v10/configuring-npm/package-json\#engines
