pnpm Files

Minor Changes

• Added a new dedupePeers setting that reduces peer dependency duplication. When enabled, peer dependency suffixes use version-only identifiers (name@version) instead of full dep paths, eliminating nested suffixes like (foo@1.0.0(bar@2.0.0)). This dramatically reduces the number of package instances in projects with many recursive peer dependencies #11070.

Patch Changes

• Fail on incompatible lockfiles in CI when frozen lockfile mode is enabled, while preserving non-frozen CI fallback behavior.

• When package metadata is malformed or can't be fetched, the error thrown will now show the originating error.

• Fixed intermittent failures when multiple pnpm dlx calls run concurrently for the same package. When the global virtual store is enabled, the importer now verifies file content before skipping a rename, avoiding destructive swap-renames that break concurrent processes. Also tolerates EPERM during bin creation on Windows and properly propagates enableGlobalVirtualStore through the install pipeline.

• Fixed handling of non-string version selectors in hoistPeers, preventing invalid peer dependency specifiers.

• Improve the non-interactive modules purge error hint to include the confirmModulesPurge=false workaround.

  When pnpm needs to recreate node_modules but no TTY is available, the error now suggests either setting CI=true or disabling the purge confirmation prompt via confirmModulesPurge=false.

  Adds a regression test for the non-TTY flow.

• Fixed false "Command not found" errors on Windows when a command exists in PATH but exits with a non-zero code. Also fixed path resolution for --filter contexts where the command runs in a different package directory.

• When a pnpm-lock.yaml contains two documents, ignore the first one. pnpm v11 will write two lockfile documents into pnpm-lock.yaml in order to store pnpm version integrities and config dependency resolutions.

• Fixed a bug preventing the clearCache function returned by createNpmResolver from properly clearing metadata cache.
