Google Map API无法与Angular 2配合使用

Question

我正面临Google Map API的问题。我已将google地图API CDN包含在我的 index.html 文件中，如下所示：

<script src="https://maps.googleapis.com/maps/api/js?key=KEY&language=de" type="text/javascript"></script> 

但它在控制台中出现错误，如下所述

'google is not defined'

比我将Google MAP CDN包含在webpack的 vendor.ts 文件中。之后，我可以看到全局 window.google 对象，但它没有附加任何功能。

  

请参阅正确控制台和错误控制台的屏幕截图。

这是我的 package.json 文件
