ng2-toastr无法在角度2中工作

Question

我想在我的角度2应用程序中使用ng2-toastr.我已按照所有说明操作,但toastr无法显示没有任何控制台错误.我还读过一些地方,ng-toastr不再适用于角度2,但没有找到任何有效的文档.我搜索了类似的问题,但没有找到任何合适的答案来解决我的问题.任何帮助,将不胜感激.

app.module.ts

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { HttpModule } from '@angular/http';
import { RouterModule } from '@angular/router';
import{ ToastModule} from 'ng2-toastr/ng2-toastr';
import { BrowserAnimationsModule} from '@angular/platform-
browser/animations';
import "hammerjs"

import { CoreModule } from './core/core.module';

import { MODULE_ROUTES, MODULE_COMPONENTS } from './app.router'

@NgModule({
  declarations: [
    MODULE_COMPONENTS
],
imports: [
   BrowserModule,
   FormsModule,
   HttpModule,
   RouterModule.forRoot(MODULE_ROUTES),
   BrowserAnimationsModule,
   CoreModule,
   ToastModule.forRoot()
],
providers: [ ],
bootstrap: [MODULE_COMPONENTS]
})
export class AppModule { }

app.component.ts

import { Component, ViewContainerRef } from '@angular/core';
import { ViewEncapsulation } from '@angular/core';
import { ToastsManager } from 'ng2-toastr/ng2-toastr';

@Component({
  selector: 'wow-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css'],
  encapsulation: ViewEncapsulation.None
})
export class AppComponent {
  constructor( public toastr: ToastsManager, private vRef: ViewContainerRef) 
  {
    this.toastr.setRootViewContainerRef(vRef);
    console.log(this.toastr);
  }

}

这就是我在我的一个组件中调用toastr方法的方法:

 login() {
   this.user_service.login(this.user).then((response) => {
     console.log(response)
     this.toastrManager.success('Successfully Logged in.')
   }

的package.json

"dependencies": {
"@angular/animations": "^4.1.3",
"@angular/common": "^4.0.0",
"@angular/compiler": "^4.0.0",
"@angular/core": "^4.0.0",
"@angular/forms": "^4.0.0",
"@angular/http": "^4.0.0",

"angular2-image-upload": "^0.6.1",
"core-js": "^2.4.1",
"hammerjs": "^2.0.8",
"jquery": "^3.2.1",
"ng2-toastr": "^4.1.2",
"rxjs": "^5.1.0",

},
"devDependencies": {
  "@angular/cli": "1.0.3",
  "@angular/compiler-cli": "^4.0.0",
  "@types/jasmine": "2.5.38" 
}

我还添加"../node_modules/ng2-toastr/bundles/ng2-toastr.min.css"了我的angular-cli.json.这是console.log

Answer 1

在angular-cli.json文件中,在styles属性中添加此行

../node_modules/ng2-toastr/bundles/ng2-toastr.min.css
