角2:找不到模块@角/动画/浏览器

Question

我打算安装Angular2-Toaster (https://github.com/Stabzs/Angular2-Toaster)，在我成功安装npm安装angular2烤面包机的例子中，我可以在错误的情况下输入它，但是我怎么看我也需要动画，所以我安装了：

npm install '@angular/animations' --save

但是，当我导入模块时出现了错误：

import {BrowserAnimationsModule} from '@angular/platform-browser/animations';

与：Cannot find module '@angular/platform-browser/animations'

我也尝试npm install和npm update -D && npm update -S。

这是我的app.module.ts：

import {BrowserModule} from '@angular/platform-browser';
import {NgModule, Component} from '@angular/core';
import {HttpModule} from '@angular/http';
import {FormsModule, ReactiveFormsModule} from '@angular/forms';
import {FormBuilder} from '@angular/forms';
import {platformBrowserDynamic} from '@angular/platform-browser-dynamic';
import {BrowserAnimationsModule} from '@angular/platform-browser/animations'; <- errors
import {ToasterModule, ToasterService} from 'angular2-toaster';

import {AppComponent} from './app.component';
... my components

@NgModule({
  declarations: [
    AppComponent,
    ... my components
  ],
  imports: [
    BrowserModule,
    FormsModule,
    HttpModule,
    BrowserAnimationsModule,
    ToasterModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule {}

你用的是角v2，没有BrowserAnimationsModule，这个模块是角v4的一部分。实际上你不需要这个进口
