No JS entry point No JavaScript entry point

react-dev-utils does not expose a JavaScript entry point in package.json. It is likely a CLI, a stylesheet, a type-definition package, or an asset bundle, so require() and import are not the way to use it.

What to do

  1. Do not require() or import react-dev-utils: it has no JavaScript entry point. Use it as a CLI (npx react-dev-utils), a stylesheet, an asset, or a type-definition package as its README describes.
  2. TypeScript: npm install -D @types/react-dev-utils

A failing require() on a CommonJS package usually means the package needs a browser/DOM global, a peer dependency, or a native binary that is not available in a bare Node.js process.
