reactjs - map 组件: Cannot read property 'initialize' of undefined

Question

我正在尝试使用 react-leaflet.js 获取基本 map 。这是我的代码:

import React from 'react';
import { Map } from 'leaflet';

const mapStyle = {
  height: '400px'
};

const mapCenter = [0, -0];
const zoomLevel = 3;

export default class MapT extends React.PureComponent {
  render() {
    return (
      <div>
        <Map
          style={mapStyle}
          center={mapCenter}
          zoom={zoomLevel}
        >
        </Map>
      </div>
    );
  }
}

但是我收到错误:

Uncaught TypeError: Cannot read property 'initialize' of undefined

    at mountIndeterminateComponent (react-dom.development.js:14003)

    at scheduleWork (react-dom.development.js:17566)
    at Object.enqueueSetState (react-dom.development.js:11695)

我做错了什么？

您需要从 react-leaflet 而不是 leaflet 导入 React leaflet 组件。

import { Map } from 'react-leaflet';
