类型“ JQuery <HTMLElement>”上不存在属性“ datepicker”

在angular 9中使用datepicker时出现错误。我的目标是阻止今天的日期之前的所有日期

我的component.ts

import { Component, OnInit, ViewChild } from '@angular/core';
import { Router, ActivatedRoute } from '@angular/router';
import { ToastrService } from 'ngx-toastr';
import { Cookie } from 'ng2-cookies/ng2-cookies';
import { HttpService } from './../../http.service';
import * as $ from 'jquery';

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

  ngOnInit(): void {

    $(document).ready(function () {

      $("#datepicker").datepicker({
        minDate: 0
      });
    })  
    }
  }

我的HTML档案

<input type="date" id="datepicker" value="2020-02-18" min="2020-02-18" max="2020-12-31">
