Start with the ng new path that runs the package-manager install with --ignore-scripts, then look at how the generated project files are written. The report proposes adding a pnpm-workspace.yaml with allowBuilds entries for @parcel/watcher, esbuild, lmdb and msgpackr-extract, but it leaves open whether that needs a pnpm version check. Done means a fresh ng new --package-manager pnpm followed by pnpm add succeeds on pnpm 11+ and older pnpm versions still work. The version-gating question should be settled with a maintainer before coding.

Description

When I create a new project with ng new --package-manager pnpm on pnpm 11 or later, ng new itself works, but the next pnpm add fails. A fresh pnpm install (after a clone, or on CI) fails the same way.

@angular/build depends on esbuild, @parcel/watcher and lmdb (which brings in msgpackr-extract), and they all have install scripts. Since pnpm 11, strictDepBuilds is on by default, so pnpm fails the install unless each of them is approved or denied under allowBuilds in pnpm-workspace.yaml. ng new doesn't hit it because it installs with --ignore-scripts, so it only shows up afterwards.

I ran into this in my project: https://github.com/Blotch-Smart-Frames/AngularLynx/issues/188

I have worked around it in my own ng add schematic, but every pnpm user gets this from a plain ng new, so I think ng new should write the pnpm-workspace.yaml for pnpm projects.

Minimal Reproduction
npx @angular/[email protected] new repro --package-manager pnpm --defaults
cd repro
pnpm add date-fns

A fresh install fails too:

rm -rf node_modules
pnpm install

Anything else relevant?

On pnpm 10 it's only a warning, so it works there.

Adding this pnpm-workspace.yaml to the new project fixes it. pnpm install, pnpm add and ng build all work after. It's the same as what this repo has in its own pnpm-workspace.yaml:

allowBuilds:
  '@parcel/watcher': false
  esbuild: false
  lmdb: false
  msgpackr-extract: false

One thing to watch out for: pnpm older than 10.26 doesn't read allowBuilds, and pnpm 9 and 10.0 fail on a pnpm-workspace.yaml that has no packages field. So it probably needs a pnpm version check.
