有同样的问题，请问楼主解决了吗？

removeLayer(layerName): boolean { if (!layerName || !this._curScene) { console.log("错误: layerName 或者 this._curScene 为空"); return false; } let layer = this._layers[layerName] if (!layer) { console.log("错误: 当前场景找不到layer", layerName); return false; } this._curScene.removeChild(layer, true); console.log("removeLayer::::",layerName) this._layers[layerName] = null; layer.destroy(); cc.sys.garbageCollect()； ResManager.getInstance().removeAll(); wx.triggerGC(); return true; }
