无法将Angular Google Maps（AGM）添加到Jhipster

Question

我已经按照https://angular-maps.com/guides/getting-started/的指南，同时尝试将谷歌地图集成到我的应用程序，但目前似乎不起作用。地图未加载，控制台上没有错误消息

}

安装agm

yarn add @agm/core

将脚本导入vendor.ts

import '../content/css/vendor.css';
import 'rxjs/add/operator/map';
import 'rxjs/add/operator/catch';
import 'rxjs/add/observable/of';
import 'rxjs/add/observable/throw';
import '@agm/core'

编辑完我执行的文件后

yarn run webpack:build

app.module.ts

import './vendor.ts';

export class JhipsterExerciseAppModule {}

export class HomeComponent implements OnInit {
    account: Account;
    modalRef: NgbModalRef;

    lat = 51.678418; // the lat 
    lng = 7.809007; // the lon

    ....

这是home.component.html

<agm-map [latitude]="lat" [longitude]="lng">
    <agm-marker [latitude]="lat" [longitude]="lng"></agm-marker>
</agm-map>

home.css

agm-map {
    height: 300px;
}

我终于能够解决问题，看起来如果在根模块中添加了库

app.module.ts

然后不知怎的，它没有在子模块级别正确拾取，所以我将它添加到目标模块，一切正常
