虚幻错误：-cook或-cookonthefly需要游戏目标

Question

在虚拟引擎4.26.2上，我试图为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

完整异常跟踪的相关部分是：

是否有传统的“游戏目标找不到”被击中的原因？

虽然不清楚它为什么工作，但复制Source目录中的默认Source文件并将其重命名为projectnameGame.Target.cs (并更改该文件的内部类名以匹配)似乎可以做到这一点。现在，在Target.cs目录中有3个Source文件。

• projectname.Target.cs
• projectnameGame.Target.cs
• projectnameEditor.Target.cs

那时一切又恢复正常..。这听起来很奇怪，但很有效！
