Unable to find solutions for all parameters in AnalysisComponent: ([object Object], ?, ?, [

As a newcomer to the Angular framework, I encountered an issue when adding project services.

Error: Can't resolve all parameters for AnalysisComponent: ([object Object], ?, ?, [object Object], [object Object], [object Object], [object Object], [object Object]).

Using Angular version 4.0.0.

I'm struggling to understand how to fix this error.

Here's the code snippet from calendar.component.ts:

    import { Component, ChangeDetectionStrategy, Inject, ViewChild, TemplateRef, OnInit } from '@angular/core';
    // other imports...

    export interface IEvent {
      start: Date,
      end: Date,
      title: string,
      color: { primary: string, secondary: string },
      actions: CalendarEventAction[]
    }

    @Component({
      // component details...
    })
    export class AnalysisComponent implements OnInit {

      // properties and methods...
      
    }

Answer №1

Your issue lies here:

constructor(private modal: NgbModal,
    private iintern: IIntern, private ievent: IEvent,
    private internService: InternService,
    private toastr: ToastrService,
    private router: Router,
    private authService: AuthService,
    @Inject(DOCUMENT) doc: any) { }

To resolve the problem, you should remove

private iintern: IIntern, private ievent: IEvent
and @Inject(DOCUMENT) doc: any from your constructor. It seems that the usage of doc is unclear.

If you need to utilize these variables, you can declare them at the top of your component like this:

export class AnalysisComponent implements OnInit {
  public event: IEvent;
  public intern: IIntern;
  public doc: DOCUMENT;

Your updated constructor should appear as follows:

constructor(private modal: NgbModal,
    private internService: InternService,
    private toastr: ToastrService,
    private router: Router,
    private authService: AuthService) { }
