     },

Answer 1

必须将ScaledSize参数与URL参数一起添加到标记的图标属性中，这与库的文档和Google的文档是一致的。

因此，如果这个对象包含两个参数：

var icon = {
  url: "https://loc8tor.co.uk/wp-content/uploads/2015/08/stencil.png",
  scaledSize: new this.props.google.maps.Size(90, 42)
};

将它们作为一个对象一起传递给标记的图标属性，如下所示：

<Marker
  onClick={this.onMarkerClick}
  key={place.id}
  place_={place}
  position={{ lat: place.lat, lng: place.lng }}
  icon={icon}
/>
