[builders]: remove getSpawnOptions usage by LukeSheard · Pull Request #14604 · vercel/vercel

LukeSheard · 2026-01-13T20:08:50Z

Overview

This is a re-apply of #14176 without the changes to remove getSpawnOptions from the build-utils package due to the breaking changes that happened.

Background

The vercel environment now populates the right tools into the toolchain when subprocess are spawned in user-space. This means that builders now no longer need to think about the toolchains they need to provision.

In this case we no longer re-create $PATH to include the node version which is needed for the build.

Code wise LGTM - Can you add in the PR what we talked privately: which change caused the previous revert and how we are avoiding the same problem now?
