Angular Nativescript角度谷歌地图-无法读取属性'；地图'；未定义的

尝试使用正常的nativescript google maps sdk在nativescript中加载google maps时出错，错误为“无法读取未定义的属性‘maps’”，代码基于主页提供的示例

忽略这一段，这里是stackoverflow接受更多文本的问题的地方

这是堆栈错误

System.err: An uncaught Exception occurred on "main" thread.
System.err: Calling js method onCreateView failed
System.err: TypeError: Cannot read property 'maps' of undefined
