在最后几步为Android失败构建一个Unity项目，我在控制台中得到了什么：
Failed running C:Program FilesUnityHubEditor2019.2.4f1EditorDatail2cpp/build/il2cpp.exe
...
il2cpp.exe didn't catch exception: System.AggregateException: One or more errors occurred. --->System.ComponentModel.Win32Exception:
The specified executable is not a valid application for this OS platform.
如何理解出了什么问题并加以解决？
完整错误文本：

内置的unity ndk本身有缺陷，您需要从谷歌安卓开发者页面安装一个稳定版本：安卓ndk，修订版16b(2017年12月(。
我尝试安装/重新安装所有类型的android工具，Unity编辑器，Visual Studio(但我没有尝试重新安装Windows:(。最后，为了解决另一个问题，我尝试更改Edit -> Project Settings -> Player -> Other Settings -> Configuration -> Scripting Backed，它将其从IL2CCP更改为Mono，并纠正了我的构建错误(构建过程变得更快(。
我仍然不知道为什么我是项目团队中唯一一个在选择IL2CCP时必须处理这个问题的人，但至少现在我可以调试项目了。
如果你对和之间的区别感兴趣，这里有关于这个话题的好答案。
