cesiumWorkerBootstrapper使用RequireJS importScripts时出错

Question

当我将铯与openlayer一起使用时遇到问题。尝试显示3D地图时，发生以下错误：

Uncaught Error: importScripts failed for Workers/createVerticesFromQuantizedTerrainMesh at http://localhost:5866/Scripts/lib/openlayers/Cesium/Workers/createVerticesFromQuantizedTerrainMesh.js
http://requirejs.org/docs/errors.html#importscripts
    at makeError (cesiumWorkerBootstrapper.js:formatted:102)
    at Function.req.load (cesiumWorkerBootstrapper.js:formatted:805)
    at Object.load (cesiumWorkerBootstrapper.js:formatted:697)
    at b.load (cesiumWorkerBootstrapper.js:formatted:381)
    at b.fetch (cesiumWorkerBootstrapper.js:formatted:370)
    at b.check (cesiumWorkerBootstrapper.js:formatted:422)
    at b.enable (cesiumWorkerBootstrapper.js:formatted:519)
    at Object.enable (cesiumWorkerBootstrapper.js:formatted:649)
    at b.<anonymous> (cesiumWorkerBootstrapper.js:formatted:512)
    at cesiumWorkerBootstrapper.js:formatted:83

我使用的代码如下：

that.ol3d = new olcs.OLCesium({
                    map: that.map
                });

                scene = that.ol3d.getCesiumScene();

                Cesium.Ion.defaultAccessToken = 'my-token';
                scene.terrainProvider = new Cesium.CesiumTerrainProvider({
                    url: Cesium.IonResource.fromAssetId(1)
                });

然后：

if (that.ol3d) {
                that.ol3d.setEnabled(true);
                that.isActivate = true;
               }

Cesium已下载到本地主机（位于我的PC上。）

研究问题，我发现在importScripts（i）行的cesiumWorkerBootstrapper.js内部发生异常。

try {
    importScripts(i),
    e.completeLoad(t)
} catch (r) {
    e.onError(makeError("importscripts", "importScripts failed for " + t + " at " + i, r, [t]))
}

有趣的是，此代码以前曾起作用。现在停止了。但是，如果我将铯连接到，系统将再次开始工作。

我将不胜感激。
