openlayers 使用feature要素拖拽问题 [已关闭]

首先放一段渲染多边形的代码块:

  /**
   * 展示多边形
   * @param values
   * @param vectorSource
   */

   import Translate from 'ol/interaction/Translate';

  addPolygon (value) {
    this.createPolygonSource();
    var features = [];
    for (var i = 0; i < value.length; i++) {
      var tempval = value[i];
      var feature = new Feature();
      feature.setGeometry(new Polygon(tempval.zbs));
      feature.setProperties({
        content: tempval.content,
        zbs:tempval.zbs,
        type:'clickPoint'
      });
      var iconStyle = new Style({
        stroke: new Stroke({  // 边框
          color: 'red',
          width: 3
        }),
        fill: new Fill({  // 填充颜色
          color: tempval.color
        })
      });
      feature.setStyle(iconStyle);
      features.push(feature);
    }
    PolygonSource.addFeatures(features);
    // 以下是鼠标经过时事件
    map.on('pointermove', function (e) {
      var pixel = map.getEventPixel(e.originalEvent);
      var hit = map.hasFeatureAtPixel(pixel);

      //=====获取到当前像素下的feature
      var feature = map.forEachFeatureAtPixel(pixel, function (feature, layer) {
        return feature;
      });
      console.log(feature)
      if (!feature) {
        // new baseMap().clearlightPolygon();
        return false;
      }

      var translate = new Translate({ //拖拽移动interaction
        features: feature //拖拽的为选择的要素
      });
      map.addInteraction(translate);
      // debugger
      map.getTargetElement().style.cursor = hit ? 'pointer' : '';
    });
  }

当代码执行到 map.addInteraction(translate) 这一行的时候,出现以下问题:

请大神看一下::
