Description

Describe the bug
I just went through this "get started from scratch "tutorial: https://tanstack.com/start/latest/docs/framework/react/build-from-scratch
I did it as an app inside my pnpm workspaces monorepo. Once I finished copy-pasting the files, I ran vite dev and I immediately got this error:
> vite dev
failed to load config from /path/to/pnpm-ws-tanstack-start/apps/bugger/vite.config.ts
error when starting dev server:
Error: Cannot find module '@tanstack/start-client-core/package.json'

Additional Context
I tried doing this outside of a pnpm workspaces environment, and it worked fine.
I also tried switching to npm workspaces instead of pnpm, and it also did not work. See this branch. Interestingly, it has a different error:
