Is it safe to delete ~/Library/pnpm/store?

Rebuildable. Your tools make it again on their own. The cost is a slower next run.

What it is
Every package version pnpm has downloaded, kept once so each project can share it instead of storing its own copy.
Made by
pnpm
If you remove it
Projects that are already installed keep working. pnpm downloads a package again the next time a project needs one it doesn't have.
How it comes back
Nothing to do, pnpm refills the store as projects need packages.

The tool's own commands

  • pnpm store path“Returns the path to the active store directory.”From pnpm.io/cli/store, read 3 Nov 2026.
  • pnpm store prune“Removes unreferenced packages from the store.” Unreferenced packages “are packages that are not used by any projects on the system.”From pnpm.io/cli/store, read 3 Nov 2026.

The proof

Verified by
vendor documentation and local test: pnpm documentation, “pnpm store”, section “prune” (https://pnpm.io/cli/store), “pnpm will download them again”; and the FAQ on the store and node_modules (https://pnpm.io/faq). Proved in a scratch store on 10 Oct 2026 with pnpm 10.17.0 (files cloned into node_modules on APFS): store deleted, then the project's code, pnpm install, pnpm add and pnpm install --frozen-lockfile each ran with exit 0 and no prompt.
Checked on
macOS 26.6.2, pnpm 10.17.0
