Turf js：如何将'FeatureCollection <Geometry>转换为'FeatureCollection <Point>'

Question

我在Angular Projects中使用Turf，版本：^ 5.1.6。我有一个点，我想将服务器检索到的JSON对象转换为FeatureCollection以找到最近的点。

我的意思是：

var targetPoint = turf.point([15.2849697, 41.6899772], {"marker-color": "#0F0"});

功能集示例展示

var points = turf.featureCollection([
    turf.point([28.973865, 41.011122]),
    turf.point([28.948459, 41.024204]),
    turf.point([28.938674, 41.013324])
]);
var nearest = turf.nearestPoint(targetPoint, points);

在这种情况下，效果很好。 但是当我添加对象时：

var mypoints = turf.featureCollection(this.bus.features)

即使我在mypoint和point之间获得相同的结构，当我将mypoints添加到nearest函数中时：

var nearest = turf.nearestPoint(targetPoint, mypoints);

我收到此错误：

Argument of type 'FeatureCollection<Geometry, { [name: string]: any; }>' is not assignable to parameter of type 'FeatureCollection<Point, { [name: string]: any; }>'

有人可以帮助我吗？
