我正在尝试创建一个地图，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。我按照指示https://openlayers.org/en/latest/doc/tutorials/bundle.html，而不安装包裹，因为我正在使用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
<html lang="en">

这与此问题相同：https://github.com/openlayers/openlayers/issues/10663
最新版本的ol.css没有包含在HTML中。
