Have a look here - you do not have pnpm installed. This repo has an npm version working: https://github.com/shaun49995/turborepo-shadcn-nextjs-monorepo-ts

@Vaidik2473 Have a look here - your package.json is not structured correctly for npm. This repo has an npm version working: https://github.com/shaun49995/turborepo-shadcn-nextjs-monorepo-ts
