[LayaAir 2.0]destroy节点后，报错

/* 从舞台移除模型对象 @param node 节点 */
base_remove(node){
if(node.numChildren<=0)return;
console.log('移除',node.name);
let obj;
for(let i=node.numChildren-1;i>=0;i--){
obj= node.getChildAt(i);
obj.destroy();
}
}
 
或者
/* 从舞台移除模型对象 @param node 节点 */
base_remove(node){
if(node.numChildren<=0)return;
console.log('移除',node.name);
node.destroyChildren();
}
 
以上两种写法都会报错
