这里是代码：

client.on('message', message => {
    let args = message.content.substring(PREFIX.length).split(" ");
    const deltef = args[1]
    const amount = parseInt(args[1]);
    if(message.member.roles.cache.has('715841880482512897')) {
        if(args[0] == 'clear') {
            if (isNaN(amount)) {
                 message.reply('that doesn\'t seem to be a valid number.');
            } else if (amount < 2 || amount > 100) {
                 message.reply('you need to input a number between 2 and 100.');
            }  
            else if (amount > 2 || amount < 100)
                message.channel.bulkDelete(args[1]);
                message.channel.send("deleted" + " " + deltef + " " + "messages" + ('✅'))
            }
    }  
}
    
);

如果你能帮到我，我会很高兴

您是否尝试在 DM 中使用此命令？因为根据 Discord.JS 文档，message.member 仅在公会中可用，如果您尝试在 DM 中使用它意味着undefined。

https://discord.js.org/#/docs/main/master/class/Message?scrollTo=member

我建议只对公会使用命令，这样就不会发生这种情况。

client.on('message', message => {
  if (message.author.bot || message.channel.type === "dm") return;
  // your code...
})
