在第 33 行，您尝试引用名为 command 的属性，但它没有在任何地方定义。
你希望命令来自哪里/你希望它持有什么？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);
