As we're going to use a sortable, We've to update app.module.ts used in ngx-bootstrap Rating chapter to use SortableModule and DraggableItemService.
Update app.module.ts to use the SortableModule and DraggableItemService.
app.module.ts
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { AppComponent } from './app.component';
import { TestComponent } from './test/test.component';
import { AccordionModule } from 'ngx-bootstrap/accordion';
import { AlertModule,AlertConfig } from 'ngx-bootstrap/alert';
import { ButtonsModule } from 'ngx-bootstrap/buttons';
