title: Angular - How to fix "ERROR TS2322: Type 'ModuleWithProviders<any>' is not assignable to type 'any[] | Type<any>'"
body: <p>I'm trying to create a webapp using Angular, but at the time of compilation I get this error which I can't solve:</p>
  
  <blockquote>
    <p>ERROR in src/app/app.module.ts(22,5): error TS2322: Type
    'ModuleWithProviders' is not assignable to type 'any[] |
    Type'.   Type 'ModuleWithProviders' is missing the following
    properties from type 'Type': apply, call, bind, prototype, and 5
    more.</p>
  </blockquote>
  
  <p>That's my app.module.ts:</p>
  
  <pre><code>import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
  import { NgModule } from '@angular/core';
  import { FormsModule } from '@angular/forms';
  import { HttpClientModule } from '@angular/common/http';
  import { RouterModule } from '@angular/router';
  import { NgbModule } from '@ng-bootstrap/ng-bootstrap';
  import { ToastrModule } from 'ngx-toastr';
  import { AppRoutingModule } from './app-routing.module';
  import { ComponentsModule } from './components/components.module';
  import { AppComponent } from './app.component';
  import { AdminLayoutComponent } from './layouts/admin-layout/admin-layout.component';
  
  @NgModule({
    declarations: [
      BrowserAnimationsModule,
      FormsModule,
      HttpClientModule,
      ComponentsModule,
      RouterModule,
      AppRoutingModule,
      NgbModule,
      ToastrModule.forRoot()
    ],
    imports: [
      AppComponent,
      AdminLayoutComponent
    ],
    providers: [],
    bootstrap: [AppComponent]
  })
  export class AppModule { }
  </code></pre>
  
  <p>The error is reported on the line: <strong>ToastrModule.forRoot()</strong></p>
  
  <p>And that's my package.json:</p>
