如何解决此错误错误：无法激活已经激活的插座

Question

我在路由器上遇到此问题，因此我的应用程序由一个主页组成，每次导航到一个孩子并重新加载页面时，我的孩子都很多。

我根据发现的答案here

尝试了此解决方案

但是不幸的是，这不能解决问题，我找不到其他可以解决我问题的答案

@ViewChild(RouterOutlet , {static : true}) outlet: RouterOutlet;

  constructor(
    private router: Router
  ) { }

  ngOnInit(): void {
    this.router.events.subscribe(e => {
      if (e instanceof ActivationStart && e.snapshot.outlet === "administration")
        this.outlet.deactivate();
    });
  }

      {

        component : AdminComponent,

      } ,
      {
        path: 'profil',
        component:ProfileComponent
      },
      {path:'performance',
      component:PerformenceComponent
      },
    ]
  } ,

我发现显示事件结果时存储了最后一个孩子，所以我想知道是否有可能清除它或启动路由器，否则我该如何解决此问题
