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。
