Cause (Documented platform behavior): Since pnpm 9, pnpm checks packageManager and errors on mismatch (package-manager-strict settings). In v11 these settings (managePackageManagerVersions, packageManagerStrict, packageManagerStrictVersion) were collapsed into pmOnFail: download | ignore | warn | error.

- https://github.com/pnpm/pnpm/issues/8087 (github_issue, 2024-05-15, reported_symptom): 'ERR_PNPM_BAD_PM_VERSION This project is configured to use v9.1.1 of pnpm. Your current pnpm is v9.1.0' — exact match enforcement in pnpm 9; closed with PR #8166.
- https://raw.githubusercontent.com/pnpm/pnpm.io/main/docs/migration.md (official_docs, unknown, documented_behavior): v11 codemod replaces managePackageManagerVersions, packageManagerStrict, packageManagerStrictVersion with pmOnFail: download|ignore|warn|error, and bumps packageManager.

Problem details
- Observed symptom
- pnpm refuses to run commands because the installed version differs from packageManager.
- Context
- Product: pnpm Component: packageManager field enforcement Operation: Running pnpm in a repo whose package.json packageManager pins a different pnpm version Affected versions: pnpm 9.x/10.x strictness settings; pnpm 11+ uses pmOnFail Environment: unknown Packages: pnpm >=9.0.0 Trigger: Global pnpm version differs from the exact version pinned in package.json packageManager (e.g. patch bump by Renovate).

Proposed fix: [pnpm 9/10] 'ERR_PNPM_BAD_PM_VERSION This project is configured to use vX of pnpm. Your current pnpm is vY' from packageManager field; pnpm 11 replaces packageManagerStrict/managePackage
Recommended action: Use corepack or let pnpm download the pinned version (v11: pmOnFail: download), or align your global pnpm; on 9/10 relax package-manager-strict settings if needed.
Option: Let pnpm/corepack provide the pinned version [evidence: official_recommended_action]
Applies when: Repos with packageManager set
Steps:
1. pnpm 11+: set pmOnFail: download in pnpm-workspace.yaml (or rely on default behavior)
2. Or enable corepack so the pinned version is used
Expected: Commands run with the pinned pnpm
Evidence basis (self-declared by the contributing chat client): untested.
