我这里依旧使用AMapLoader插件

代码如下

  // 初始化高德地图
    initMap() {
      AMapLoader.load({
        key: "fb35c92d4019cfafeca876fd5514bb47", //key值是key值 和安全密钥不同
        version: "2.0", // 指定要加载的 JSAPI 的版本，缺省时默认为 1.4.15
        plugins: [
          "AMap.GeoJSON",
          "AMap.MarkerClusterer",
          "AMap.MouseTool",
          "AMap.Geocoder",
          "AMap.Marker",
          "AMap.Polyline",
          "AMap.InfoWindow",
        ], // 需要使用的的插件列表,用到的再次注册，如比例尺'AMap.Scale'等
      }).then((AMap) => {
        // 初始化地图
        this.map = new AMap.Map("mapContainer", {
          viewMode: "3D", // 是否为3D地图模式
          zoom: 14.0, // 初始化地图级别
          center: [114.885796, 40.768555], //中心点坐标
          resizeEnable: true,
        });
        //使用CSS默认样式定义地图上的鼠标样式
        this.map.setDefaultCursor("pointer");

        let styleName = "amap://styles/whitesmoke";
        this.map.setMapStyle(styleName);
