Witam wszystkich.
Bardzo proszę o pomoc.
Jestem w trakcie poznawania Nx, a w ramach tego współtworzę projekt eshopu (MEAN) żeby mieć co pokazać na rozmowie jaki Junior.
Projekt znajduje się pod adresem: https://github.com/terabajt/myShop-MEAN-Full-Stack-FRONTEND
Chodzi o to, że jestem na etapie implementacji karty zamówienia. Aplikacja 'eshop' działa prawidłowo - jednak jak próbuję wstrzyknąć do komponentu ProductItemComponent (myShop-MEAN-Full-Stack-FRONTEND/libs/products/src/lib/components/product-item/product-item.component.ts) bibliotekę orders (ponieważ jest tam CartService (libs/orders/src/lib/services/cart.service.ts) ) w konstruktorze w sposób:
import { Component, Input } from '@angular/core';
import { Product } from '../../models/product';
import { CartService } from '@webappshop/orders';
@Component({
selector: 'products-product-item',
templateUrl: './product-item.component.html',
styles: []
})
export class ProductItemComponent {
@Input()
product!: Product;
constructor(private cartService: CartService) {}
onAddProductToCart() {
//TUTAJ UŻYJĘ cartService
}
}
po zapisywaniu projektu dostaję burzę błędów:

✖ Failed to compile.
Dodam tylko, że do aplikacji w tym samym nx (admin) wstrzykuję również moduł, w którym znajduje się ten serwis (libs/orders/src/lib/orders.module.ts) i tam nie ma takich problemów.
Jak tylko usunę w komponencie import:
import { CartService } from '@webappshop/orders';
oraz:
constructor(private cartService: CartService) {}
Błędy znikają i aplikacja renderuje się poprawnie.
Bardzo proszę o pomoc.
