# npm WARN EBADENGINE Unsupported engine / The engine "node" is incompatible with this module

**Code:** `EBADENGINE` · **Category:** Node.js · **Seen on:** Node.js

A package requires a different Node.js version than the one you’re running.

## Meaning

package.json "engines" declares supported versions. npm warns (EBADENGINE); yarn and pnpm can fail. Running anyway may break at runtime.

## Common causes

- Node too old for a dependency
- Node too new for a legacy package
- CI using a different Node version than local

## Quick fix

1. Switch Node version with nvm (nvm use 20)
2. Add .nvmrc to the project
3. Pin Node in CI (setup-node)

## Detailed fix by platform

### Node.js

1. `echo "20" > .nvmrc && nvm use`

## How to diagnose

1. **Required** — Version range in the message
2. **Current** — node -v
