恐怕错误消息并不能告诉我太多信息。 这不是与 Spine 相关的错误。 您正在尝试访问未定义或 null 的变量，该变量应该保存对 SpinePlayer 的引用。 该引用尚不存在。 这让我认为这可能是你的 Vue 生命周期的问题。 如果您发布代码或完整的复制示例，我可以提供更多帮助。
I'm afraid that error message doesn't tell me much. It's not a Spine related error. You are trying to access a variable that's undefined or null, which supposedly should hold a reference to a SpinePlayer. That reference doesn't exist yet. This leads me to think that it's likely an issue with your Vue life cycle. If you post code or a full reproduction sample, I can be of more help.
