javascript - Angular 6 GeoFire 初始化 GeoFire 不是构造函数

Question

我在 Angular 6 上初始化 GeoFire 时遇到问题。当我尝试初始化 GeoFire 时，

geofire__WEBPACK_IMPORTED_MODULE_2__ is not a constructor

抛出错误。

下面是我的依赖和代码。

"@angular": "6.0.2",
"firebase": "5.0.3",
"geofire": "4.1.2",
"angularfire2": "5.0.0-rc.9"
"typescript": "2.7.2"

import * as GeoFire from 'geofire';
import * as firebase from 'firebase/app';
[![enter image description here][1]][1]
@Component({
    selector: 'app-near-by-page',
    templateUrl: './near-by-page.component.html',
    styleUrls: ['./near-by-page.component.scss']
})
export class NearByPageComponent extends PageComponent {
    constructor() {
        super();

        // Generate a random Firebase location
        const firebaseRef = firebase.database().ref().child('locations');

        // Create a new GeoFire instance at the random Firebase location
        const geoFire = new GeoFire(firebaseRef);
        const geoQuery = geoFire.query({
            center: [51.294, -0.245],
            radius: 1
        });
    }

}

导入

const geofire = require('geofire');

用法

const geoFireInstance = new geofire.GeoFire(ref);
