可能很难找到一个完整的解决方案，因为下载一个新的版本总是需要互联网连接。 然而，每次失败都要启动Spine启动器并下载新的版本可能有点麻烦，所以从命令行界面更新可能会使反复尝试更容易。
Spine [-u <version>]将更新您的Spine编辑器到您指定的版本。更多信息请参见以下页面。

Hmm. Since downloading a new version always requires an Internet connection, it may be difficult to solve completely. However, it may be a bit time-consuming to launch the Spine launcher and download the version every time it fails, so updating from the command line interface may make repeated attempts easier.
Spine [-u <version>] will update your Spine editor to the version you specify. See the following page for more information:
