首次尝试使用Leaflet显示和使用动态地图,当我尝试向LayerGroup添加新的标记层时,我遇到了错误.

这是我的Map对象,封装了leaflet的功能:

function Map() {
  //properties/fields
  var map;
  var layers = [];  

  return {
    setMap: function(aMap) {map=aMap;},
    setView: function(aView) {map.setView(aView);},
    addLayer: function(aLayer, name) {layers[name] = aLayer; map.addLayer(aLayer);},    
    addListings: function(anArr, name) {
        var mLayer = [];                                           
        for (var i = 0; i < anArr.length; i++) {
            var aMarker = L.marker([anArr[i][0], anArr[i][1]]);
            mLayer.push(aMarker);                            
        };
        layers[name] = L.layerGroup(mLayer);
        layers[name].addTo(map);
    },
    updateListings: function(anArr, name) {
        var mLayer = [];
        for (var i = 0; i < anArr.length; i++) {
            console.log(anArr[i].entity.locations[0].lat, anArr[i].entity.locations[0].lng);
            var aMarker = …

我一直在谷歌搜索和阅读这几天。由于依赖关系，我无法将我的 Laravel 项目从 5.7 更新到 5.8。当我更新 composer.json 中的依赖包版本值并尝试执行 Laravel 更新时，它会忽略我的更新，实际上将它们恢复为原始值。
