Ich kann diesen Fehler nicht beheben. Ich habe eine Suchleiste und ein ngFor. Ich versuche, das Array mit einer benutzerdefinierten Pipe wie folgt zu filtern:

import { Pipe, PipeTransform } from '@angular/core';

import { User } from '../user/user';

@Pipe({
  name: 'usersPipe',
  pure: false
})
export class UsersPipe implements PipeTransform {
  transform(users: User [], searchTerm: string) {
    return users.filter(user => user.name.indexOf(searchTerm) !== -1);
  }
}

Verwendung

<input [(ngModel)]="searchTerm" type="text" placeholder="Search users">

<div *ngFor="let user of (users | usersPipe:searchTerm)">
...
</div>

Error

zone.js:478 Unhandled Promise rejection: Template parse errors:
The pipe 'usersPipe' could not be found ("
<div class="row">
    <div  
    [ERROR ->]*ngFor="let user of (user | usersPipe:searchTerm)">
