VS显示100条左右的错误，UE热编译也不能通过。原因可能是[名字.Build.cs]文件的错误，缺少一些内容，比如说如果要写UserWidget类，那么就要在 ]名字.Build.cs]
中加入如下内容：

public class beibaoxitong : ModuleRules
{public beibaoxitong(ReadOnlyTargetRules Target) : base(Target){PCHUsage = ModuleRules.PCHUsageMode.UseExplicitOrSharedPCHs;PublicIncludePaths.AddRange(new string[] {System.IO.Path.Combine(ModuleDirectory, "Public")// ... add public include paths required here ...});PrivateIncludePaths.AddRange(new string[] {System.IO.Path.Combine(ModuleDirectory, "Private")// ... add other private include paths required here ...});PublicDependencyModuleNames.AddRange(new string[]{"Core","CoreUObject","Engine","SlateCore","UMG"			// ... add other public dependencies that you statically link with here ..., "InputCore", "EnhancedInput","ProceduralMeshComponent"
});PrivateDependencyModuleNames.AddRange(new string[]{"CoreUObject","Engine","Slate","SlateCore",// ... add private dependencies that you statically link with here ...	"UMGEditor", "UMGEditor","UMG", "InputDevice", "InputDevice", "InputDevice" 
});DynamicallyLoadedModuleNames.AddRange(new string[]{// ... add any modules that your module loads dynamically here ...});}
}

根据你的文件进行添加。如果说依然有如图的问题，那你就去原来的项目里看看哪些没加上去。
