使用 react-leaflet 時如何修復“TS2769 沒有重載匹配此調用”

[英]How to fix 'TS2769 No overload matches this call' when using react-leaflet

我正在嘗試在我的反應應用程序上實現 Leaflet map 組件。 這就是我的組件的樣子:

import React from "react";
import { Map, Marker, Popup, TileLayer } from "react-leaflet";
import "./styles.scss";

const position = [51.505, -0.09];

const LocationMap: React.FC = () => {
  return (
    <section className="find-container container">
      <h2 className="find-title title">Find us</h2>
      <Map center={position} zoom={12}>
        <TileLayer
          url="https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png"
          attribution="&copy; <a href=&quot;http://osm.org/copyright&quot;>OpenStreetMap</a> contributors"
        />
      </Map>
    </section>
  );
};

export default LocationMap;

當我運行“npm start”時,項目無法編譯,並顯示此錯誤:

No overload matches this call.
  Overload 1 of 2, '(props: Readonly<MapProps>): Map<MapProps, Map>', gave the following error.
    Type 'number[]' is not assignable to type 'LatLng | LatLngLiteral | LatLngTuple | undefined'.
      Type 'number[]' is missing the following properties from type '[number, number]': 0, 1
  Overload 2 of 2, '(props: MapProps, context?: any): Map<MapProps, Map>', gave the following error.
    Type 'number[]' is not assignable to type 'LatLng | LatLngLiteral | LatLngTuple | undefined'.
      Type 'number[]' is not assignable to type 'LatLngTuple'.  TS2769

有人知道如何解決嗎?

TypeScript 抱怨,因為center屬性被聲明為數組( number[] ),而它應該是元組類型:

const position:[number,number] = [51.505, -0.09];

LatLngLiteral類型:

const position: LatLngLiteral = { lat: 51.505, lng: -0.09 };

LatLng類型:

const position = new LatLng(51.505,-0.09);

總而言之,要使用帶有 TypeScript 的react-leaflet ,需要安裝以下軟件包:

  • leaflet作為依賴
  • react-leaflet和類型定義@types/react-leaflet

最后但同樣重要的是,根據文檔leaflet CSS 文件需要包括在內,例如,通過index.html

<link rel="stylesheet" href="https://unpkg.com/leaflet@1.6.0/dist/leaflet.css"
   integrity="sha512-xwE/Az9zrjBIphAcBb3F6JVqxf46+CDLwfLMHloNu6KEQCAWi6HcDUbeOfBIptF7tcCzusKFjFw2yuvEpDL9wQ=="
