目的是用谷歌地图显示搜索。
我在离子/角度项目中遇到此错误
运行时错误
没有 MapsAPILoader 的提供者!

错误:没有 MapsAPILoader 的提供程序!

在应用程序模块中
从'@agm/core'导入{AgmCoreModule};
从“angular2-google-maps/core/services/google-maps-api-wrapper”导入{GoogleMapsAPIWrapper};
进口:[
AgmCoreModule.forRoot({
apiKey:'********',库:[“地点”]
})
]
然后在组件页面
从 'angular2-google-maps/core' 导入 {MapsAPILoader};
构造函数(私有mapsAPILoader:MapsAPILoader){
this.mapsAPILoader.load().then(() => {
让 autocomplete = new google.maps.places.Autocomplete(this.searchElementRef.nativeElement, {
类型:[“地址”]
});
autocomplete.addListener("place_changed", () => {
this.ngZone.run(() => {
//获取地点结果
让地点:google.maps.places.PlaceResult = autocomplete.getPlace();
//验证结果
if (place.geometry === undefined || place.geometry === null) {
返回;
}
this.latitude = place.geometry.location.lat();
this.longitude = place.geometry.location.lng();
this.zoom = 12;
});
});
});
}
html页面

所以..我不知道会发生什么。在哪里找到提供者或我必须放在哪里。
