按照Angular 2动画文档(
https://angular.io/docs/ts/latest/guide/animations.html),我迁移到Angular 4.0.1.这是我的package.json的一部分:
"@angular/common": "~4.0.1",
"@angular/compiler": "~4.0.1",
"@angular/core": "~4.0.1",
"@angular/forms": "~4.0.1",
"@angular/http": "~4.0.1",
"@angular/platform-browser": "~4.0.1",
"@angular/platform-browser-dynamic": "~4.0.1",
"@angular/router": "~4.0.1",
"@angular/animations": "~4.0.1",
"typescript": "^2.2.2",
"zone.js": "^0.8.4"

app.module.ts
import { NgModule } from '@angular/core';
import { BrowserModule, Title } from '@angular/platform-browser';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
...
@NgModule({
imports: [ BrowserModule, BrowserAnimationsModule, appRouting, FormsModule ],
...
})
在我的自定义组件中,我还导入了角度动画:
import { trigger, state, style, animate, transition } from '@angular/animations';
我的视图(templateUrl分配的外部视图!)如下所示:
<div class="container" [@containerState]="showContainer">
...
</div>
问题是:我总是收到控制台错误消息:
错误:未捕获(在承诺中):错误:找到合成属性@containerState.请在您的应用程序中包含“BrowserAnimationsModule”或“NoopAnimationsModule”.
当我删除这个合成属性一切正常,但我无法使用角度动画.
有任何想法吗?我不使用angular-cli!
更新container.component.ts
import { Component, OnInit, OnDestroy, EventEmitter, HostListener, Input, Output } from '@angular/core';
import { trigger, state, style, animate, transition } from '@angular/animations';
@Component({
templateUrl: '...',
selector: '...',
animations: [
trigger('containerState', [
state('hide', style({transform: 'translateY(-102%)'})),
transition('hide => show', [
animate(500, style({transform: 'translateY(0)'}))
]),
transition('show => hide', [
animate(500, style({transform: 'translateY(-102%)'}))
])
])
]
})
目前正在运行……
我做了什么?删除完整的node_modules文件夹并运行全新安装.之后一切正常.很奇怪!我将尝试将另一个Angular 2.x应用程序升级到Angular 4.x.
最佳答案 Angular2认为前缀’@’表示’综合侦听器’,应该由您指定的动画模块覆盖.但是,您自己使用@符号,< div class =“container”[@containerState] =“showContainer”>
尝试删除’@’并查看是否适合您.
