Property'Draw'在类型'typeof Control'上不存在

Question

我试图实现一个带有小册子和其他小册子插件的地图组件。问题是由于某些原因，其他插件无法从TypeScript中使用。

例如我无法编译瓣叶战平插件代码，并得到错误：

Property 'Draw' does not exist on type 'typeof Control'

mapbox.component.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}', { 
      attribution: 'Map data &copy; <a href="http://openstreetmap.org">OpenStreetMap</a> contributors, <a href="http://creativecommons.org/licenses/by-sa/2.0/">CC-BY-SA</a>, Imagery © <a href="http://mapbox.com">Mapbox</a>', 
      maxZoom: 18, 
      id: 'mapbox.streets', 
      accessToken: '...' 
     }).addTo(this.map); 

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

Answer 1

我解决了问题，通过导入瓣叶画

import 'leaflet-draw'; 

不知道为什么它没有被tsconfig进口，但耶它的作品！

Answer 2

感谢@aclokay的洞察力。我会通过添加你完成这个答案，你也忘了改变标准的传单导入。例如：

// import * as L from 'leaflet'; 
// --> Doesn't work : Property 'Draw' does not exist on type 'typeof Control'. 
declare const L: any; // --> Works 
import 'leaflet-draw'; 

export function drawPlugin(map: any) { 
    const drawnItems = L.featureGroup().addTo(map); 

    const drawControl = new L.Control.Draw({ 
    edit: { 
     featureGroup: drawnItems, 
    }, 
    draw: { 
     polygon: false, 
     polyline: false, 
     marker: false, 
     circlemarker: false 
    } 
    }); 
    map.addControl(drawControl); 

    map.on(L.Draw.Event.CREATED, function (event) { 
    const layer = event.layer; 

    drawnItems.addLayer(layer); 
    }); 
}
