当我在 Angular 中调用一个组件时，它没有出现，即使端点发生变化，home 组件仍然出现

Question

我创建了一个“学生”组件，当我调用它时，它没有出现在它应该位于的端点中！相反，home 组件仍然出现在学生端点 (/student)

学生部分

import { Component, OnInit } from '@angular/core';

@Component({
  selector: 'app-student',
  templateUrl: './student.component.html',
  styleUrls: ['./student.component.css']
})
export class StudentComponent implements OnInit {

  constructor() { }

  ngOnInit(): void {
  }

}

<p>student works!</p>

import { NgModule } from '@angular/core';
import { RouterModule, Routes } from '@angular/router';
import { StudentComponent } from './components/student/student.component';

const routes: Routes = [{ path: 'student', component: StudentComponent },];

@NgModule({
  imports: [RouterModule.forRoot(routes)],
  exports: [RouterModule],
})
export class AppRoutingModule {}
