在談到這個例子mapbox-GL-JS ... https://www.mapbox.com/mapbox-gl-js/example/3d-extrusion-floorplan/擠出多邊形的3D室內映射......在Mapbox
當我與我的API密鑰運行此示例代碼,我只得到了地圖以「自然史博物館」爲中心,沒有任何牆壁擠壓。我在這裏錯過了什麼?其他示例似乎直接從複製粘貼中運行。

謝謝大家對你的幫助
它在爲我工作在http://jsbin.com/vevefalope/edit?html,output 當您嘗試它時,您是否在控制檯中看到錯誤? – mollymerp
您的geojson加載出了問題我想,您可以自己託管geojson或將json複製並粘貼到代碼中。 –
