Question

因此，基本上，我正在尝试使用message.mentions.channels将通知发送到特定频道
前!announce #announcements Today is a great day!

错误：

代码：

    let channel = message.mentions.channels.first();
    if (!channel) return 
    let announcement = args.slice(1).join(" ");
  
    channel.send(announcement)

错误是您传递变量的方式：

在您拥有的其他命令文件之一中：

execute(client, message, args) {
  //this works
}

在公告命令文件中，您拥有：

execute(message, args){
  console.log(message, args);

  /* =>
  Client {
   ...
  }

  Message {
   ...
  }
  */
}

因此，在这种情况下，message是实际的客户端对象，而args是实际的消息对象，因此只需修复可变点，

您在announce.js中的新执行函数

execute(client, message, args) {
  //rest of code here
}

我正在尝试发出公告命令，但出现错误
