问题描述

            import { Injectable, Inject } from '@angular/core';
            import { Subject } from "rxjs/Subject";
            import { CompleterData, CompleterItem } from 'ng2-completer';
            import { ProgramService } from '../program.service';
            import { asEnumerable } from 'linq-es5';
            import { CacheService } from '../../../core/services/cache.service';

            @Injectable()
            export class ProgramIntelligentSearch extends Subject<CompleterItem[]> implements CompleterData {
                constructor(private programService: ProgramService,
                    private cacheService: CacheService,
                    @Inject(Array) private lessonTypes: Array<any>,
                    @Inject(Array) private programTypes: Array<any>,
                    @Inject(Array) private languages: Array<any>
                    ) {
                    super();
                }
      --------------------------------------------------------------------------  
        import { Observable } from "rxjs/Observable";
        import { CompleterItem } from "../components/completer-item";
        export interface CompleterData extends Observable<CompleterItem[]> {
            search(term: string): void;
            cancel(): void;
            convertToItem?(data: any): CompleterItem;
        }

推荐答案

您将必须添加@Inject，以便可以解决其依赖性.

You will have to add @Inject so that its dependency can be resolved.

因此对于服务内部的自定义服务，请使用@Inject注入其依赖项

So for custom services inside your service Inject its dependency with @Inject

在您的代码中，将您的自定义服务替换为

In your code replace your custom services with

@Inject(ProgramService) private programService: ProgramService, @Inject(CacheService) private cacheService: CacheService,
