Describe the bug

When upgrading our service to use pnpm v9, nixpacks is still using pnpm v8

package.json

  "engines": {
    "node": "18.x"
  },
  "packageManager": "pnpm@9.0.3",

To reproduce

No response

Expected behavior

Nixpacks (corepack by proxy) respects the packageManager field

Environment

nixpacks version 1.21.3
aws codebuild

Hmm Nixpacks should definitely be using corepack to install pnpm 9. Looks like we are not for pnpm for some reason.

I believe I have the same issue, downgrading to pnpm v8.x solved it for me :(

Have the same issue here on pnpm 9. Our service is in a monorepo, and the rest of the app depends on v9, so unfortunately can't downgrade to v8. Using a nixpacks.toml file installing v9 works:

providers = ["node"]

[phases.install]
cmds = ["npm install -g corepack", "corepack enable", "corepack prepare pnpm@9.1.0 --activate", "pnpm install"]

However, would appreciate support for v9 out of the box.

Thanks for the tips, it did work for me !
