Unreal Error: Game target is required with -cook or -cookonthefly
在 Unreal Engine 4.26.2 上，我正在尝试为 Win64 打包一个 Blueprint/C++ 混合项目。
但是，我遇到了以下错误：
LogMainFrame: Project does not require temp target
LogLauncherProfile: Found promoted target with matching version at ../../../Engine/Binaries/Win64/UE4Game-Win64-Shipping.target

命中“未找到游戏目标”是否有常规原因？
虽然不清楚它为什么起作用，但复制 Source 目录中的默认 projectname.Target.cs 文件并将其重命名为 projectnameGame.Target.cs（同时更改内部 class 名称该文件匹配）似乎可以解决问题。 Source 目录中现在有 3 个 Target.cs 文件。
- projectname.Target.cs
- projectnameGame.Target.cs
- projectnameEditor.Target.cs
那时一切都恢复正常了...这看起来很奇怪，但确实有效！
