here is my project app module app.module.ts:
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { ServiceService } from './apiServices/service.service';
import { AppComponent } from './app.component';
import { HttpModule } from '@angular/http';
import { RouterModule, Routes } from '@angular/router';
import { HomeComponent } from './home/home.component';
import { ProfileComponent } from './profile/profile.component';
import { AppRoutingModule } from './app-routing.module';
import { MasonryModule } from 'angular2-masonry';
import { LoadersCssModule } from 'angular2-loaders-css';
const appRoutes: Routes = [
{ path: '', component: HomeComponent },
{ path: 'profile/l/:id', component: ProfileComponent }
];
@NgModule({
declarations: [
AppComponent, HomeComponent, ProfileComponent
],
imports: [
BrowserModule,
HttpModule,
MasonryModule,
RouterModule,
AppRoutingModule,
RouterModule.forRoot(appRoutes),
LoadersCssModule
],
providers: [ServiceService],
bootstrap: [AppComponent]
})
export class AppModule { }
the following errors appear when adding: import { MasonryModule } from 'angular2-masonry'; and adding MasonryModule to imports
ERROR in ./node_modules/angular2-masonry/index.ts Module build failed: Error: /Users/developer/my-app/node_modules/angular2-masonry/index.ts is not part of the compilation output.
