您好，非常感谢您访问这个问题：D。
这是我写的一段代码：

for (let i = 0; i < game.channels.length; i++) {
  let channel = msg.guild.channels.cache.find(game.channels[i]); //Line number 249
  msg.guild.channels.cache.get(channel.id).delete();
}
for (let i = 0; i < game.players.length; i++) {
  let member = msg.guild.members.cache.find(game.players[i]);
  console.log(member); //I used this line to see what "member" stored
  msg.guild.members.cache.get(member.id).roles.remove(alive);
}
for (let i = 0; i < game.watchers.length; i++) {
  let member = msg.guild.members.cache.find(game.watchers[i]);
  console.log(member); //I used this line to see what "member" stored
  msg.guild.members.cache.get(member.id).roles.remove(dead);
}
for (let i = 0; i < game.werewolf.length; i++) {
  msg.guild.channels.cache
    .find((c) => c.name == "werewolf-chat" && c.type == "text")
    .permissionOverwrites.get(game.werewolf[i])
    .delete();
}

我的目标是：

  • [在第一个循环中]删除 ID 中定义的频道game.channels。
  • [在第二个循环中]从aliveID 定义在game.players.
  • [在第三个循环中]alive从ID 中定义的用户中删除名为“Dead”的角色（其 ID 存储为） game.watchers。
  • [在第 4 个循环中]删除 ID 中定义的用户的频道权限game.werewolf。

但是，以上目标都没有实现；相反，在命令提示符中，出现了：

C:\Users\Admin\node_modules\@discordjs\collection\dist\index.js:160
            if (fn(val, key, this))
                ^

    at WebSocket.emit (events.js:310:20)

期待您的帮助来解决这个问题。再次感谢您的关心。
P/s：我对 Javascript 和 Discord bot 开发非常陌生，所以如果您能尽可能以最清晰和最详细的方式回答这个问题，我将不胜感激。
