CCNode#rotation. RotationX != RotationY. Don't know which one to return"

创建一个物理场景。
scene = cc.Scene:createWithPhysics()

然后往这个场景里添加骨骼动画的时候报错了。
local rootNode = cc.CSLoader:createNode(aniName)
local action = cc.CSLoader:createTimeline(aniName)
rootNode:runAction(action)
self.view:addChild(rootNode)

求大神指导。
