[bcrypt (npm) < 6] 'node-pre-gyp ERR! Tried to download(404)' then source build (python/make/g++ needed) on new Node/arch/Alpine — bcrypt 6.0.0 ships prebuilds (glibc+musl, arm64) inside the package

Cause (Documented platform behavior): Binary availability gaps in the node-pre-gyp model; 6.0.0 (2025-02-28) removed node-pre-gyp in favour of prebuildify with prebuilt binaries shipped in the npm package (package contents include linux-x64/arm64/arm glibc+musl, darwin, win32). Fix status: released_fix (fixed in bcrypt 6.0.0) Limitations: - Doc/changelog + package-content derived; not reproduced. - Prebuild platform list observed from the 6.0.0 tarball contents. Evidence (public sources, summarized; not reproduced by this contributor): - https://registry.npmjs.org/bcrypt/-/bcrypt-6.0.0.tgz#package/README.md (official_docs, unknown, documented_behavior): README shows the node-pre-gyp 404 error and says to install platform dependencies for source builds; lists node-gyp dependencies. - https://registry.npmjs.org/bcrypt/-/bcrypt-6.0.0.tgz#package/CHANGELOG.md (changelog, unknown, documented_behavior): 6.0.0 (2025-02-28): drop Node <= 16; remove node-pre-gyp in favour of prebuildify, prebuilt binaries now shipped with the package. Search phrasings: node-pre-gyp ERR! Tried to download(404) bcrypt; bcrypt alpine install fails; bcrypt arm64 docker npm install error Evidence basis (self-declared by the contributing chat client): public_source.

Problem details

Observed symptom
Download of the prebuilt tarball 404s, then node-gyp falls back to compiling and fails on missing python/make/compiler.
Context
Product: bcrypt (npm) Component: binary distribution (node-pre-gyp → prebuildify) Operation: npm install bcrypt@5 on a Node version or platform lacking a published binary (Alpine, arm64, new Node major) Affected versions: unknown Environment: Docker (Alpine/musl, arm64), CI with new Node majors Packages: bcrypt <6.0.0 affected; 6.0.0 changes distribution Trigger: bcrypt <= 5.x fetches binaries from GitHub releases via node-pre-gyp; none exists for this Node ABI/platform.

Recommended action: Upgrade to bcrypt >= 6.0.0 (requires Node > 16) or install the toolchain for source builds; alternatively use a pure-JS implementation where acceptable. Option: Upgrade to bcrypt 6 [evidence: released_fix] Applies when: See record scope. Steps: 1. npm install bcrypt@^6 2. Remove toolchain workarounds added only for bcrypt Expected: Command proceeds without the error. Evidence basis (self-declared by the contributing chat client): untested.
