Question

有人可以帮忙吗，我不知道如何解决这是我得到的代码低于尝试运行命令处理程序的错误，我认为您聪明的人可以提前感谢

错误：index.js：33 let commandfile = client.commands.get（command.slice（prefix.length））; ^

在第33行，您尝试引用名为command的属性，但未在任何地方定义该属性。
您希望命令从哪里来/您希望它来自何处？似乎缺少的步骤是检查message属性，对其进行处理并将其用作命令，例如similar to this：

  // Our standard argument/command name definition.
  const args = message.content.slice(client.config.prefix.length).trim().split(/ +/g);
  const command = args.shift().toLowerCase();

  // Grab the command data from the client.commands Enmap
  const cmd = client.commands.get(command);

有人可以帮助cmd未定义
