Question

JavaScript的新手，并试图创建一个非常基本的机器人来管理小型服务器。在完成了一些教程之后，我到了这一点：

const Discord = require('discord.js');
const { prefix, token } = require('./config.json')
const client = new Discord.Client();

client.once('ready', () => {
    console.log('Ready!')
})

client.on('message', message => {
    if (message.member.hasPermission(['KICK_MEMBERS', 'BAN_MEMBERS'])) {

        if(message.content.startsWith(`${prefix}kick`)) {

            let member = message.mentions.members.first();
            member.kick().then((member) => {
                message.channel.send(":wave: " + member.displayName + " has been kicked!")

            })
        }

    }
})

client.login(token);

运行“ node”之后。并尝试用我的“ *”前缀踢人，它返回此错误消息：

TypeError: Cannot read property 'kick' of undefined

我对此还很陌生，但是有其他编码语言的经验。有什么建议吗？

Answer 1

member变量被分配了未定义的值。因此，请检查message.mentions.members.first();或message响应的值。

创建Discord机器人时如何解决“ TypeError：无法读取未定义的属性'kick'”？
