我收到此错误：

core.js:1624 ERROR Error: Uncaught (in promise): Error: Can't resolve all parameters for GroupAddComponent: ([object Object], [object Object], ?, [object Object], [object Object], [object Object]).

我们有一个 AngularJS 和 Angular 6 混合应用程序。到目前为止，我有三个 Angular 6 组件。每当我单击最新组件ManageProgramComponent然后返回并单击其他两个组件中的任何一个时GroupAddComponent，GroupEditComponent我都会收到上述错误。但是，每当我单击任一组组件，然后单击ManageProgramComponent，一切正常。

GroupComponents 使用相同的模块，即：

API服务：

import { Injectable, Inject } from '@angular/core';
import { Observable, of } from 'rxjs';
import { catchError, map, tap } from 'rxjs/operators';
import { HttpClient, HttpHeaders, HttpParams } from '@angular/common/http';
import { UpgradeModule } from '@angular/upgrade/static';

@Injectable({
    providedIn: GroupModule

export class ApiService {
    private baseUrl = window['API_URL']; // URL to web api
    private httpOptions = {};

    constructor(
        private http: HttpClient,
        private upgrade: UpgradeModule,
        @Inject('Util') Util: any,
        @Inject('Session') Session: any
    ) {
        let headersMap = {
            'Content-Type': 'application/json',
            Authorization: Util.getToken()
        };
        if (Session.entered_as() && Session.getUser())
            headersMap['EnteredAs'] = Session.getUser().email;

        this.httpOptions = {
            headers: new HttpHeaders(headersMap)
        };
    }
}

有什么错误？

问题出在 ApiService 中，您试图在其中将模块作为依赖项注入，

constructor(
        private http: HttpClient,
        private upgrade: UpgradeModule //remove this
}

constructor(private api: ApiService) {}如上所述，这也可能导致冲突，因此请将其注释掉。

确定是否需要，因为您不使用它，如果不从所有组件/服务中删除它。

此外，您不应该依赖另一个服务中的服务。在这种情况下，您应该使用 @injectable。
