我的 Discord 机器人（Minecraft 服务器状态机器人）有问题

Question

这是机器人的index.js 脚本：

const { Client, RichEmbed } = require('discord.js')

const bot = new Client()

const util = require('minecraft-server-util')

const token = 'bot_token'

const PREFIX = 'l.'

bot.on('ready', () => {
    console.log('Bot has come online.')
})

bot.on('message', message => {

    let args = message.content.substring(PREFIX.length).split(' ')

    switch (args[0]) {
        case 'status':

            util.status('IP', (PORT), (error, reponse) => {
                if (error) throw error
                const Embed = new RichEmbed()
                    .setTitle('Server Status')
                    .addField('Server IP', reponse.host)
                    .addField('Server Version', reponse.version)
                    .addField('Online Players', reponse.onlinePlayers)
                    .addField('Max Players', reponse.maxPlayers)

                message.channel.send(Embed)
            })
            break

    }

})

bot.login(token)

当我在控制台输入node . 并在 Discord 服务器上输入l.status 时，它会在控制台上显示此错误：

有人可以帮忙吗？我也尝试了很多不同的解决方案，但都没有奏效。

Answer 1

这是基于假设的答案，因为我以前从未使用过minecraft-server-util。还假设您使用的是最新的minecraft-server-util，

基于错误；

预期的“选项”是一个对象或未定义，得到数字

并且，基于this commit，您应该将第二个参数作为对象而不是PORT，因为它是StatusOptions的类型而不是number.

所以，而不是；

util.status('IP', (PORT), (error, reponse) => {

你应该这样做；

util.status('IP', {
  port: (PORT)
}, (error, reponse) => {

Answer 2

您使用的是过时版本的 discord.js。在终端中输入npm i discord.js@latest。在最新版本的 discord.js 中，RichEmbed() 已被删除并替换为 MessageEmbed()。
