How to fix npm ERR! code ERESOLVE npm ERR! Could not resolve optional dependency in npm

npmBEGINNERLOW

An optional dependency cannot be resolved. Either add/align it, or ignore it if your platform does not need it.

What this error means

Optional deps may fail to install on unsupported platforms. npm treats some resolution failures as errors unless you allow optional failures.

1Check if the optional dependency is required

If it is truly optional for your platform, you can allow it to fail without blocking install.

2Try installing a compatible version

Align the optional dep version with peers if you need it on this platform.

3Allow optional failures when acceptable

Use npm config optional=false to skip installing optional deps, or catch failures with npm install --no-optional if they are not needed.

Optional deps are often platform-specific (e.g., fsevents). If not needed, skip them; otherwise, use a compatible version or platform.
