在angularjs应用中添加映射

我试图添加谷歌地图在我的angularjs应用程序添加下面的脚本标签:-

 <script src="https://maps.googleapis.com/maps/api/js?key=[AddingMySecretKeyHere]&callback=initMap" async defer></script>

我从https://developers.google.com/maps/documentation/javascript/adding-a-google-map

但我得到低于错误，而gulp构建它

[10:13:46] Starting 'custom-templates'...
[10:13:47] Finished 'custom-less' after 29 ms
