rails new AppName --css {sass,bootstrap} --js esbuild fails on npm set-script

When I run : rails new MyApp --js esbuild --css boostrap --database postgresql (same with sass instead of bootstrap)

It fails at this step :

Appending Bootstrap JavaScript import to default entry point

      append  app/javascript/application.js

Add build:css script

         run  npm set-script build:css "sass ./app/assets/stylesheets/application.bootstrap.scss ./app/assets/builds/application.css --no-source-map --load-path=node_modules" from "."

Do i miss an npm dependency, is my node/npm too old ?

Got it. I need npm v7+ (npm install -g npm@latest)
