Start by reviewing the reported node-gyp rebuild failures for bufferutil, utf-8-validate, and pathwatcher, especially the Python-version error in the installation output. Reproduce installation on the stated macOS and Python versions, then determine the relevant dependency or install-script entry point. Done means the package installs without the pathwatcher failure.
