如果你查看ember-leaflet v2的文档，标记图层组件可能是你的问题。

{{#leaflet-map lat=lat lng=lng zoom=zoom}}    

  {{tile-layer url="http://{s}.basemaps.cartocdn.com/light_all/{z}/{x}/{y}.png"}}    

  {{#marker-layer location=emberConfLocation}}
    <h3>The Oregon Convention Center</h3>
    777 NE Martin Luther King Jr Blvd<br>
    Portland, OR 97232
  {{/marker-layer}}    

  {{#marker-layer location=hotel}}
    <h3>Hotel</h3>
  {{/marker-layer}}    

{{/leaflet-map}}

我猜

{{layers.marker}}无效
