ngx-perfect-scrollbar | Angular wrapper library for the Perfect Scrollbar | Frontend Framework library

Error Image

package.json

I followed this guide to set up swiper slider in my Angular 8 application.

I get the below error when importing NgxUsefulSwiperModule into app.module.ts

ERROR in ./node_modules/ngx-useful-swiper/fesm2015/ngx-useful-swiper.js Module not found: Error: Can't resolve 'swiper/bundle' in 'C:\Users\Dan\NewAngular\node_modules\ngx-useful-swiper\fesm2015'

I have a ProjectView component that renders a ProjectViewBudget component as a "child"(it is generated inside a dynamic tab component with ComponentFactoryResolver) by using a simple service. The child changes this value, the parent only subscribes to it. For now I only used it in the child, to see it working, but i get this error, why?
