Note: I had a similar issue at some other lib. There I could resolve it by using typescript 5.5 - see angular/angular#56945

Confirming the same error on 15.1.1:

/angular/node_modules/ngx-scrollbar/smooth-scroll/public_api.ngtypecheck.d.ts' not found. [plugin angular-compiler]

It seems that packages built with ng-packagr 18.1.0 requires TS 5.5. What do we do at this point?

[daniel-sc]

@MurhafSousli I think upgrading this project to TS 5.5 should be the best solution. As it is only a devDependency this should not impact downstream projects.
