你是说你从Spine 4.1导出骨架时，将导出设置中的 版本选项设为3.8？
Are you saying that you are exporting the skeleton from Spine 4.1 with the export settings set to the Version option to 3.8?

如果是这样，请注意，导出的数据在spine-unity运行时3.8下将无法正常加载。版本选项用于导出可以被旧版本的Spine编辑器加载的数据。它不提供可用于旧版Spine运行系统的数据。
If so, note that the exported data will not load properly with the spine-unity runtime 3.8. The Version option is used to export data that can be loaded by an older version of the Spine editor. It does not give data that can be used with an older Spine runtimes version.

如果你想保留运行时版本，你需要将该Spine项目降级到3.8。反之，如果你想保持你的Spine项目版本为4.1，你需要升级运行时版本。运行时的升级指南可以在这里找到。
If you want to keep the runtime version, you need to downgrade that Spine project to 3.8. Conversely, if you want to keep your Spine project version as 4.1, you need to upgrade the runtime version. The runtime upgrade guides can be found here:

请注意，虽然这可能适用于您当前的资产，但运行时不支持从 Spine Editor 版本 4.1 导出的版本设置为“3.8”的 json 资产，并且将来可能无法正确读取。 如果您遇到任何其他问题，请查看上面 Misaki 的帖子，了解如何正确解决此问题。
Please note that while this might work with your current assets, exported json assets with version set to 3.8 from Spine Editor version 4.1 are not supported by the runtimes and may fail to read correctly in the future. If you run into any other issues, please check out the posting by Misaki above to see how to properly resolve this.
