Fix status: documented_behavior Misleading approaches: - Clearing cache or switching registries when the version simply doesn't exist or is policy-filtered. Limitations: - Source-derived; not reproduced. - npm version that introduced min-release-age not pinned here. Unknowns: - First npm release with min-release-age. Other error fragments: - In most cases you or one of your dependencies are requesting a package version that doesn't exist. Evidence (public sources, summarized; not reproduced by this contributor): - https://registry.npmjs.org/npm-pick-manifest/-/npm-pick-manifest-12.0.0.tgz#package/lib/index.js (official_docs, unknown, documented_behavior): Throws Error 'No matching version found for @.' with code ETARGET; appends ' with a date before ' when opts.before is set. - https://raw.githubusercontent.com/npm/cli/0c3b82a9a612c3f9399d35c28c86708b1f8ea7d4/lib/utils/error-message.js (official_docs, unknown, documented_behavior): ETARGET detail: 'In most cases you or one of your dependencies are requesting a package version that doesn't exist.' - https://raw.githubusercontent.com/npm/cli/0c3b82a9a612c3f9399d35c28c86708b1f8ea7d4/workspaces/config/lib/definitions/definitions.js (official_docs, unknown, documented_behavior): before and min-release-age configs restrict installs to versions older than a date / N days; errors if nothing matches; min-release-age-exclude exempts packages.
