传单地图标记群集未显示图标

我正在尝试使用leafletjs制作地图，但无法使marker clusters正常工作。我希望它显示标记聚类的默认图标，但是完全不显示标记聚类图标。这里有一个演示：传单地图标记群集未显示图标

var map = L.map('mapid').setView([51.505, -0.09], 13); 
 

 
L.tileLayer('https://api.tiles.mapbox.com/v4/{id}/{z}/{x}/{y}.png?access_token=pk.eyJ1IjoibWFwYm94IiwiYSI6ImNpejY4NXVycTA2emYycXBndHRqcmZ3N3gifQ.rJcFIG214AriISLbB6B5aw', { 
 
    maxZoom: 18, 
 
    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>', 
 
    id: 'mapbox.streets' 
 
}).addTo(map); 
 

 
var markers = L.markerClusterGroup(); 
 
markers.addLayer(L.marker([51.505, -0.09])); 
 
markers.addLayer(L.marker([51.506, -0.09])); 
 
map.addLayer(markers);

<script src="https://leaflet.github.io/Leaflet.markercluster/dist/leaflet.markercluster-src.js"></script> 
 
<div id="mapid" style="height:380px;"></div>

这个代码是完全基于http://leafletjs.com/examples/quick-start/和https://github.com/Leaflet/Leaflet.markercluster#usage的例子，所以我会想象它会工作给出的例子，但它似乎并不像这实际上显示集群背后的图标。

我发现markerClusterGroup有一个名为_defaultIconCreateFunction的方法，但它似乎没有被调用（或者如果它确实被调用，它什么也不做）。

那么我在这里做错了什么？

您还需要MarkerCluster.css和MarkerCluster.Default.css

var map = L.map('mapid').setView([51.505, -0.09], 13); 
 

 
L.tileLayer('https://api.tiles.mapbox.com/v4/{id}/{z}/{x}/{y}.png?access_token=pk.eyJ1IjoibWFwYm94IiwiYSI6ImNpejY4NXVycTA2emYycXBndHRqcmZ3N3gifQ.rJcFIG214AriISLbB6B5aw', { 
 
    maxZoom: 18, 
 
    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>', 
 
    id: 'mapbox.streets' 
 
}).addTo(map); 
 

 
var markers = L.markerClusterGroup(); 
 
markers.addLayer(L.marker([51.505, -0.09])); 
 
markers.addLayer(L.marker([51.506, -0.09])); 
 
map.addLayer(markers);
