这是我的代码,目前标记和工具提示根本没有显示。 控制台未显示任何错误,我不知道该怎么做。

根据文档,存在标记未显示的问题,但从我读过的其他问题来看,标记似乎是不可见的,如果标记不可见,popup/tooltip 仍会显示。我什么也没得到,看不到代码有问题。

我也尝试过使用自定义标记图像,但结果相同。没有

Marker 组件不应该是 Tile Layer 的子组件,如 Vue2-Leaflet 的示例所示,而是 Map(或 Layer Group)的子组件:

    <l-map
      :zoom="zoom"
      :center="center"
    >
      <l-tile-layer
        :url="url"
        :attribution="attribution"
      />
      <l-marker :lat-lng="withTooltip">
        <l-tooltip>
          <div>
            I am a tooltip
          </div>
        </l-tooltip>
      </l-marker>
    </l-map>
