Platform

Environment

OS	Linux x64 (Ubuntu)
Node	v22.22.0
pnpm	v10.30.1
@tanstack/react-start	1.162.4

Additional context

First error: esbuild postinstall fails with:

Error: Expected "0.27.3" but got ""

The scaffold pins esbuild@0.27.3 directly in dependencies, which has a broken postinstall script under Node 22.

Second error (after removing esbuild from dependencies and letting it be a transitive dep): lightningcss native binary missing:

Error: Cannot find module '../lightningcss.linux-x64-gnu.node'

pnpm's strict symlinking means the lightningcss-linux-x64-gnu optional dependency binary never gets linked into lightningcss's node/ directory.

Start by locating the TanStack Start scaffold template and its package.json dependency definitions, then reproduce the failure with pnpm install and pnpm dev on Linux. Investigate the reported esbuild postinstall and lightningcss native-binary errors; done means a freshly scaffolded project installs and starts without manual dependency changes.
