类型“typeof Control”上不存在属性“Draw”

我正在尝试使用传单和其他传单插件实现地图组件。问题是其他插件由于某种原因无法在 TypeScript 上运行。

例如，我无法使用 leaflet-draw 插件编译代码并收到错误：

类型“typeof Control”上不存在属性“Draw”

地图框组件.ts

import { DataService } from "../data-service.service";
import { Component, OnInit } from '@angular/core';


import * as $ from 'jquery';
/// <reference types="leaflet" />
/// <reference types="leaflet-draw" />

declare var require: any


@Component({
    selector: 'app-mapbox',
    templateUrl: './mapbox.component.html',
    styleUrls: ['./mapbox.component.css']
})

export class MapboxComponent implements OnInit {

    constructor(private dataService: DataService) { }
    // helper flags
    map: L.Map = null;
    aggreagte: boolean = false;

    ngOnInit() {
        // Prepare map
        this.map = L.map('resultmap').setView([51.505, -0.09], 1);
        //
        L.tileLayer('https://api.tiles.mapbox.com/v4/{id}/{z}/{x}/{y}.png?access_token={accessToken}', {

            maxZoom: 18,
            id: 'mapbox.streets',
            accessToken: '...'
        }).addTo(this.map);

        var drawnItems = L.featureGroup();
        this.map.addLayer(drawnItems);
        var control = new L.Control.Draw();
        ...

    "types":[
      "jquery",

    ]
  }

我通过导入传单绘图解决了这个问题

import 'leaflet-draw';

不知道为什么它没有被 tsconfig 导入，但是它可以工作！
