When does this happen?

IF When a package declares Node 18 support in its engines field and README, but a direct dependency requires Node 20 or higher.

How others solved it

THEN Audit all direct and transitive dependencies for Node engine compatibility before relying on a package's declared support. Use 'npm ls --depth=0' to inspect the dependency tree and check each package's engines field, or run 'npm install --engine-strict' to enforce engine checks during installation. If incompatibilities are found, consider pinning a compatible older version of the dependency or dropping Node 18 support for that project.

npm install --engine-strict  # fails if any dependency engine requirement is unmet
