The EBADENGINE error is similar to ENOTSUP and occurs when packages have incompatible engine requirements. This can happen in dependency trees where different packages need conflicting Node versions.
EBADENGINE indicates an engine compatibility failure at some level of your dependency tree. This can be your direct dependency requirements or a transitive dependency. npm 7+ reports these more strictly than npm 6. This often surfaces when older packages in the dependency tree haven't been updated to support newer Node.js versions.
Read the full error:
npm install 2>&1 | grep -A5 EBADENGINE
# Shows which package and what it requiresSkip all engine checks:
npm install --ignore-engines
# Or set in config
npm config set engine-strict falseLook for updated or alternative packages:
# Check if package is maintained
npm view problematic-package time.modified
# Search for alternatives
npm search "similar functionality"Force different version:
{
"overrides": {
"problematic-package": "newer-version"
}
}This may introduce other issues.
Match the required version:
# Find common requirement
nvm install 18
nvm use 18
npm installHelp fix the ecosystem:
1. Check if issue already exists
2. Open issue on package repo
3. Submit PR updating engines field
4. Fork and fix if unmaintained
Some packages over-specify engine requirements when they would actually work fine. Test with --ignore-engines and report to maintainers if it works. In large projects, consider using npm-force-resolutions or pnpm for better dependency control. Corporate environments may need to audit and fork unmaintained dependencies.
