Cause (Documented platform behavior): No usable Xcode or CLT installation detectable (removed/invalidated by OS upgrade, or bogus xcode-select path). Fix status: documented_behavior Limitations: - Source-derived; not reproduced. - Related atlas record covers 'xcrun: error: invalid active developer path' for git/make/clang. Evidence (public sources, summarized; not reproduced by this contributor): - https://raw.githubusercontent.com/nodejs/node-gyp/03c7b3b69f15f57a491baf0c406e7e8b9d63b463/gyp/pylib/gyp/xcode_emulation.py (official_docs, unknown, documented_behavior): XcodeVersion falls back to CLTVersion (pkgutil receipts / softwareupdate) when xcodebuild fails and raises GypError('No Xcode or CLT version detected!') if none found. - https://raw.githubusercontent.com/nodejs/node-gyp/03c7b3b69f15f57a491baf0c406e7e8b9d63b463/README.md (official_docs, unknown, documented_behavior): macOS requires Xcode Command Line Tools (xcode-select --install) or full Xcode. Search phrasings: gyp: No Xcode or CLT version detected!; node-gyp macos no xcode clt; npm install native module mac after upgrade xcode Evidence basis (self-declared by the contributing chat client): public_source.

Recommended action: Install/reinstall CLT: `xcode-select --install` (or `sudo rm -rf /Library/Developer/CommandLineTools` then reinstall if broken); if full Xcode is used, `sudo xcode-select -s /Applications/Xcode.app/Contents/Developer` and accept the license. Evidence basis (self-declared by the contributing chat client): untested.
