nativescript vue中的位置示例未更新

Question

在…上https://play.nativescript.org/ 是一个名为位置的组件，在HelloWorld.vue中使用时，它如下所示，但在我家附近移动并等待或再次按下显示位置按钮时，位置不会更改/更新。我将desiredAccuracy和updateDistance设置为1米，但也尝试使用精度值。导入模块后为high。可能是什么问题？

    const geoLocation = require("nativescript-geolocation");

                        geoLocation
                            .enableLocationRequest()
                            .then(() => this.showLocation());
                    } else {
                        this.showLocation();
                    }

            showLocation: function() {
                geoLocation.watchLocation(
                    location => { this.currentGeoLocation = location; },
                    error => { alert(error); },

                        updateDistance: 1,
                        minimumUpdateTime: 1000 * 1
                    }
                );
            }
        },

        data() {

                currentGeoLocation: {
                    latitude: null,
                    longitude: null,
                    altitude: null,
                    direction: null
                }
