我正在尝试创建地图，正如我在其他网站和示例中看到的那样，每个人都可以通过鼠标点击和拖动来移动他们的地图。但是我的地图根本不会移动，有人知道我做错了什么吗？

这些是我正在使用的 components.ts 和 component.html 文件。我按照https://openlayers.org/en/latest/doc/tutorials/bundle.html上的说明进行操作，但没有安装包裹，因为我使用的是 angular。

map.component.ts

ngOnInit(): void {
  this.mapInit();
  }

   mapInit() {
   var mousePositionControl = new MousePosition({
         coordinateFormat: createStringXY(4),
         projection: 'EPSG:4326',
         // comment the following two lines to have the mouse position
         // be placed within the map.
         className: 'custom-mouse-position',
         target: document.getElementById('mouse-position'),
         undefinedHTML: ' '
       });

          var source = new OSM();
          var overviewMapControl = new OverviewMap({
            layers: [
              new TileLayer({
                source: source
              })
            ]
          });

          this.map = new Map({
          target: 'map',
          interactions: defaultInteractions().extend([
              new DragRotateAndZoom
            ]),
            layers: [
              new TileLayer({
                source: source
              }),
            ],
            view: new View({
              center: fromLonLat([19.833549, 45.267136]),
              zoom: 7
            }),
            controls: defaultControls().extend([
            overviewMapControl,
            new FullScreen(),
            mousePositionControl,
            new ZoomToExtent({
            extent: [
               813079.7791264898, 5929220.284081122,
               848966.9639063801, 5936863.986909639,
             ]
             })
            ])
          });

map.component.html

这与此问题相同：https ://github.com/openlayers/openlayers/issues/10663

HTML 中不包含最新版本的 ol.css。

添加：

<link rel="stylesheet" href="https://cdn.jsdelivr.net/gh/openlayers/openlayers.github.io@master/en/v6.2.1/css/ol.css">
