Unity Android 构建失败：指定的可执行文件不是此 OS 平台的有效应用程序
Unity Android build failure: The specified executable is not a valid application for this OS platform
为 Android 构建一个 Unity 项目在最后一步失败，这里是我在控制台中得到的：
Failed running C:\Program Files\Unity\Hub\Editor19.2.4f1\Editor\Data\il2cpp/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.
如何了解问题所在并修复它？

内置的unity ndk本身有bug，你需要从google android开发者页面安装一个稳定版本：Android NDK, Revision 16b (December 2017).
我尝试了 installing/reinstalling 各种 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，它从 IL2CCP 更改为 Mono，它解决了我的构建错误（并且构建过程变得更快）。
我仍然不知道为什么我是项目团队中唯一必须在选择IL2CCP时必须处理此问题的人，但是至少现在我可以调试项目。[= = = 15=]
