Getting warns from material-carousel on npm install

[HDeiro]

When I execute npm install I've been receiving these errors

npm WARN @ngmodule/[email protected] requires a peer of @angular/material@^7.0.0 but none is installed. You must install peer dependencies yourself.

npm WARN @ngmodule/[email protected] requires a peer of rxjs@~6.3.3 but none is installed. You must install peer dependencies yourself.

I have @angular/[email protected] and [email protected].
