Answer 1

您需要捕获错误并对其执行某些操作。为此，需要添加错误捕获。修复问题的代码在这里：

initMap(): Promise<any> {
    this.mapInitialised = true;//part 1
    return new Promise((resolve) => {
        this.geolocation.getCurrentPosition().then(
            (position) => {// Part 2
            let latLng = new google.maps.LatLng(position.coords.latitude, position.coords.longitude);
            let mapOptions = {
                center: latLng,
                zoom: 15,
                mapTypeId: google.maps.MapTypeId.ROADMAP;
            }

            this.map = new google.maps.Map(this.mapElement, mapOptions);
            resolve(true);
        },
        // Here is the error catching that needs to be added
        err =>{
             console.log(' Error : ' + JSON.stringify(error));
        });
    });
}

建议您尝试将错误视为：

this.geolocation.getCurrentPosition().then(
(position) => {  
    /* your code */
} err =>{
      alert('Error message : '+ err.message);
 });

通过执行此操作，您将收到正确的错误消息。
