尝试使用 Watson SDK for Unity 时如何修复此错误？

Question

感谢您查看此内容。我是 Unity 的新手，正在努力了解如何修复此错误。

Assets/Watson/Scripts/Logging/Logger.cs(115,53)：错误 CS0311：类型 IBM.Watson.DeveloperCloud.Logging.LogSystem' 不能用作泛型类型或方法 Singleton 中的类型参数 T。没有从 IBM.Watson.DeveloperCloud.Logging.LogSystem' 到 `UnityEngine.MonoBehaviour

的隐式引用转换

这是导致错误的行：

public static LogSystem Instance { get { return Singleton<LogSystem>.Instance; } }

上下文是这样的：

 /// <summary>
  /// This singleton class maintains the of list of installed reactors and handles all LogRecord 
  /// objects. See the static class Log for functions the end user of this system should actually
  /// be calling. This class is thread safe.
  /// </summary>
  public class LogSystem
  {

Answer 1

public static LogSystem Instance 
{ 
     get 
     { 
          return instance; 
     } 
}
private static LogSystem instance;
// Ctor of the class
public LogSystem()
{ 
    if(instance == null) { instance = this;}
}

这是一个非常基本的单例模式实现。你可以在网上找到更高级的。
