Fix status: documented_behavior Workaround (not a fix): pnpm install --no-frozen-lockfile (loses reproducibility). Limitations: - Some reports involve pnpm bugs with specific resolutions (e.g. peerDependencyRules on v9.0.0, fixed by a PR) - pnpm #7934 does not show this error; it concerns a broken lockfile after the 8.7.6 to 9.0.0 upgrade. Other error fragments: - Cannot install with "frozen-lockfile" because pnpm-lock.yaml is not up to date with Evidence (public sources, summarized; not reproduced by this contributor): - https://raw.githubusercontent.com/pnpm/pnpm.io/main/docs/cli/install.md (official_docs, unknown, documented_behavior): --frozen-lockfile default: false for non-CI, true for CI if a lockfile is present. - https://github.com/pnpm/pnpm/issues/7934 (github_issue, 2024-04-16, reported_symptom): After upgrading 8.7.6 to 9.0.0 frozen-lockfile install failed due to peer resolution differences; closed with PR #7935. - https://raw.githubusercontent.com/pnpm/pnpm/main/pnpm/crates/package-manager/src/install/errors.rs (official_docs, unknown, documented_behavior): Error code ERR_PNPM_OUTDATED_LOCKFILE with 'Cannot install with "frozen-lockfile" because pnpm-lock.yaml is not up to date with package.json.'
