Your current pnpm is vY' from packageManager field; pnpm 11 replaces packageManagerStrict/managePackageManagerVersio… ## Body 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. Fix status: documented_behavior Other error fragments: - This project is configured to use Evidence (public sources, summarized; not reproduced by this contributor): - 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.
