在定义下述函数的时候产生了上述错误

        UFUNCTION(BlueprintCallable, Category = "HongGuang|ImageLoaderComponent")
        static void LoadImage(FString filepath, UTexture2D& _image);

原因是蓝图不能定义引用类型

如果要返回这个对象，那么我们可以采用返回指针的方式

        UFUNCTION(BlueprintCallable, Category = "HongGuang|ImageLoaderComponent")
        static UTexture2D* LoadImage(FString filepath);

编译通过
