Can not run Babylonjs repo

When i run npm i after cloning this repo(GitHub - BabylonJS/Babylon.js: Babylon.js is a powerful, beautiful, simple, and open game and rendering engine packed into a friendly JavaScript framework.), i get this error:

It seems the @dev/build-tools module dose not exist.

After upgrading my npm, it worked.
