Angular CanActivate Guard错误

我在app.module.ts上收到此错误消息

[ts] Type'（{path：string; component：typeof LoginComponent;} | {path：string; canActivate :( typeof AuthG ...'不能分配给'Route []' . 输入'{path：string ; component：typeof LoginComponent;} | {path：string; canActivate :( typeof AuthGu ...'不能分配给'Route'类型 . 输入'{path：string; canActivate：（typeof AuthGuard）[]; component：typeof HeaderComponent;}'不能赋值为'Route' . 对象文字只能指定已知属性，但'canActivate'在'Route'类型中不存在 . 你的意思是写'canDeactivate'吗？

我检查了我的防护文件，没有发生错误 . 但是在我的app.module.ts中，返回一个类似的错误 . 这是我的AuthGuard：

import { Injectable } from '@angular/core';
import { AuthService } from '../../services/auth.service';
import { CanActivate, ActivatedRouteSnapshot, RouterStateSnapshot, Router } from '@angular/router';
import { Observable } from 'rxjs/Rx';

class Permissions{
  canActivate(user, token):boolean{
    return true;
  }
}

@Injectable()
export class AuthGuard implements CanActivate {
  constructor(
    private permissions : Permissions,
    private router: Router,
    private authService: AuthService,
){}

  canActivate(
    next: ActivatedRouteSnapshot,
    state: RouterStateSnapshot
  ): Observable<boolean> | Promise<boolean> | boolean {
    let user;
    let token;
    let level;
    if (this.authService.loggedIn(user, token, level)) {
      return true;
    }else{
      this.router.navigate(['/']);
      console.log('Please login first.');
      return false;
    }
  }
}

这是我的app.module.ts文件：
