Angular - How to fix "ERROR TS2322: Type 'ModuleWithProviders<any>' is not assignable to type 'any[] | Type<any>'"

I'm trying to create a webapp using Angular, but at the time of compilation I get this error which I can't solve:

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.

That's my app.module.ts:

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 { }

The error is reported on the line: ToastrModule.forRoot()

And that's my package.json:

{
  "name": "pum-pum-pum",
  "version": "0.0.0",
  "scripts": {
    "ng": "ng",
    "start": "ng serve",
    "build": "ng build",
    "test": "ng test",
    "lint": "ng lint",
    "e2e": "ng e2e"
  },
  "private": true,
  "dependencies": {
    "@angular/animations": "~7.2.0",
    "@angular/common": "~7.2.0",
    "@angular/compiler": "~7.2.0",

    "zone.js": "~0.8.26"
  },
  "devDependencies": {

    "@angular/cli": "~7.3.7",
    "@angular/compiler-cli": "~7.2.0",
    "@angular/language-service": "~7.2.0",
    "@types/node": "~8.9.4",
    "@types/jasmine": "~2.8.8",
    "@types/jasminewd2": "~2.0.3",
    "codelyzer": "~4.5.0",
    "jasmine-core": "~2.99.1",
    "jasmine-spec-reporter": "~4.2.1",
    "karma": "~4.0.0",
    "karma-chrome-launcher": "~2.2.0",
    "karma-coverage-istanbul-reporter": "~2.0.1",
    "karma-jasmine": "~1.1.2",
    "karma-jasmine-html-reporter": "^0.2.2",
    "protractor": "~5.4.0",
    "ts-node": "~7.0.0",
    "tslint": "~5.11.0",
    "typescript": "~3.2.2"
  }
}

Please someone help me.

Add all this in import not in @NgModule({declarations:
FormsModule, HttpClientModule, ComponentsModule, RouterModule, AppRoutingModule, NgbModule, ToastrModule.forRoot() any module or importation is not added in declarations.

this will be like - imports: [ BrowserAnimationsModule, FormsModule, HttpClientModule, ComponentsModule, RouterModule, AppRoutingModule, NgbModule, ToastrModule.forRoot() ],

  1. declarations is save components,pipes or directives.
  2. imports is save modules.
@NgModule({
  // right
  imports: [
    BrowserAnimationsModule,
    FormsModule,
    HttpClientModule,
    ComponentsModule,
    RouterModule,
    AppRoutingModule,
    NgbModule,
    ToastrModule.forRoot()
  ],
  // right
  declarations: [
    AppComponent,
    AdminLayoutComponent
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

As i see, you have added Modules under declarations and components under imports, you should add Modules under imports and components under declarations.
