Ignored build scripts: @swc/core, better-sqlite3. Run "pnpm approve-builds" — pnpm 10 skips dependency postinstall

pnpm@10#pnpm#postinstall#lifecycle-scripts#onlybuiltdependencies#supply-chain
Ignored build scripts: @swc/core, better-sqlite3. Run "pnpm approve-builds" to pick which dependencies should be allowed to run scripts.
Fix

Interactive: run pnpm approve-builds after pnpm install and select the packages; it records the allow-list and runs their builds.

Or declare it explicitly (pnpm 10):

// package.json
{
  "pnpm": {
    "onlyBuiltDependencies": ["esbuild", "better-sqlite3", "@swc/core"]
  }
}

In later pnpm 10.x releases pnpm approve-builds writes onlyBuiltDependencies into pnpm-workspace.yaml instead (creating that file if needed). To silence the warning for packages whose scripts you do NOT want, list them in ignoredBuiltDependencies. To restore the pre-v10 run-everything behaviour (not recommended): "pnpm": { "neverBuiltDependencies": [] }.

Commit the allow-list: CI starts from a clean store, so a local-only approval still leaves CI with the warning. Note pnpm 11 removed onlyBuiltDependencies in favour of allowBuilds (see the pnpm 11 entry).

Symptom

After upgrading to pnpm 10, pnpm install succeeds but prints a warning like:

Ignored build scripts: @swc/core, better-sqlite3.
Run "pnpm approve-builds" to pick which dependencies should be allowed to run scripts.

Then native modules fail at runtime (e.g. better-sqlite3 bindings missing, esbuild/sharp/prisma binaries not downloaded, husky hooks not installed). Older advice assumes postinstall of dependencies always runs.

Cause

pnpm 10.0.0 (2025-01-07): "Lifecycle scripts of dependencies are not executed during installation by default!" Only packages explicitly allow-listed may run preinstall/install/postinstall. Your own project's scripts still run.

Verify

Delete node_modules, run pnpm install: no "Ignored build scripts" line, and the native package loads (e.g. node -e "require('better-sqlite3')").
