Angular2解析器错误意外令牌

我跑的时候得到： –

>     EXCEPTION: Template parse errors: Parser Error: Unexpected token | at column 32 in [ngFor let awsoffer of awsoffers| keys2] in
> AWSOfferListComponent@2:9 ("<h3>AWS Offer List Elements:</h3> <ul>

>     <th>{{awsoffer.key}}</th>
>     <div *ngFor="let awso2 o"): AWSOfferListComponent@2:9 Parser Error: Unexpected token . at column 28 in [ngFor let awso2 of
> awsoffer.value| keys2] in AWSOfferListComponent@4:9 ("   <table

>     <th>{{awsoffer.key}}</th>
>     <div [ERROR ->]*ngFor="let awso2 of awsoffer.value| keys2">
>     <tr>
>     <td>{{awso2.key}}</td> "): AWSOfferListComponent@4:9

我已经在angular-seed项目之外使用了这个代码,所以在将逻辑移动到结构中时我必须有一些错误 – 但是我无法看到它是什么.搜索谷歌似乎表明它与管道模块没有加载,但它似乎是 – 没有404错误.

零件：-

import { Component,OnInit } from 'angular2/core';
import { AWSOfferService } from '../../../shared/services/aws-offer.service';
import { AWSOffer } from './aws-offer';
import { KeysPipe } from '../../../shared/pipes/keys.pipe';
import { KeysMultPipe } from '../../../shared/pipes/keys2.pipe';




@Component({
  selector: 'aws-offer-list',templateUrl: './pages/aws-offers/components/aws-offer-list.html',styles: ['.th {color:red;}'],pipes : [KeysPipe,KeysMultPipe]
})

export class AWSOfferListComponent implements OnInit {
  constructor (private AWSOfferService: AWSOfferService) {}
  errorMessage: string;
  awsoffers: AWSOffer[];
  ngOnInit() { this.getAWSOffers(); }

  getAWSOffers() {
      this.AWSOfferService.getAWSOffers().subscribe(awsoffers => this.awsoffers = awsoffers,error =>  this.errorMessage = <any>error);
  }
}

模板：-

<h3>AWS Offer List Elements:</h3>
<ul>
  <table *ngFor="let awsoffer of awsoffers| keys2">
    <th>{{awsoffer.key}}</th>
    <div *ngFor="let awso2 of awsoffer.value| keys2">
    <tr>
    <td>{{awso2.key}}</td>
    <td>{{awso2.value}}</td>
    </tr>
    </div>
  </table>
</ul>

管道定义： –

import { PipeTransform,Pipe } from 'angular2/core';

@Pipe({name: 'keys2'})
export class KeysMultPipe implements PipeTransform {
  transform(value,args:string[]) : any {
    let keys = [];
    for (let key in value) {
      keys.push({key: key,value: value[key]});
    }
    return keys;
  }
}

有任何想法吗？
