Node.js Discord.js 12.5.1消息嵌入不工作

我正在制作一个机器人，作为一个有趣的项目来管理我的日常任务。但我被困在这里：

TypeError: Cannot read property 'MessageEmbed' of undefined

我似乎找不到一个符合我需要的答案。这是我的密码：

client.on('message', message => {
    if (message.content.startsWith('t!test')) {
        const embed = new Discord.MessageEmbed()
    .setTitle("This is a title")
    .setDescription("This is a description")
    .setTimestamp()
    .setFooter("This is a footer")
    .setAuthor("This is the author's name")
    .addField("This is a field", "this is its description")
    .setImage("https://images-ext-2.discordapp.net/external/cC-YBJkH2GXnX7MHMASUM9Gle1S1im3rDJj2K54A28w/%3Fcid%3D73b8f7b19a5ccc575679c0a7fc4a673b753e4ce993f35223%26rid%3Dgiphy.mp4/https/media2.giphy.com/media/Q8bEDnj9hZd6vivXSZ/giphy.mp4")
    .setThumbnail("https://images-ext-2.discordapp.net/external/cC-YBJkH2GXnX7MHMASUM9Gle1S1im3rDJj2K54A28w/%3Fcid%3D73b8f7b19a5ccc575679c0a7fc4a673b753e4ce993f35223%26rid%3Dgiphy.mp4/https/media2.giphy.com/media/Q8bEDnj9hZd6vivXSZ/giphy.mp4")
    message.channel.send(embed)
    }
});

任何帮助都将不胜感激，因为我已经被困在这个问题上3个小时了

编辑：我修正了错误！以下是出现此问题的任何人的代码：

require('dotenv').config();
const { MessageEmbed, Client } = require('discord.js');
const Discord = require('discord.js');

const client = new Discord.Client();

client.on('ready', () => {
    console.log(`Bot logged in as ${client.user.tag}`)
});

client.on('message', message => {
    if (message.content.startsWith('t!test')) {
        const embed = new Discord.MessageEmbed()
    .setTitle("This is a title")
    .setDescription("This is a description")
    .setTimestamp()
    .setFooter("This is a footer")
    .setAuthor("This is the author's name")
    .addField("This is a field", "this is its description")
    .setImage("https://images-ext-2.discordapp.net/external/cC-YBJkH2GXnX7MHMASUM9Gle1S1im3rDJj2K54A28w/%3Fcid%3D73b8f7b19a5ccc575679c0a7fc4a673b753e4ce993f35223%26rid%3Dgiphy.mp4/https/media2.giphy.com/media/Q8bEDnj9hZd6vivXSZ/giphy.mp4")
    .setThumbnail("https://images-ext-2.discordapp.net/external/cC-YBJkH2GXnX7MHMASUM9Gle1S1im3rDJj2K54A28w/%3Fcid%3D73b8f7b19a5ccc575679c0a7fc4a673b753e4ce993f35223%26rid%3Dgiphy.mp4/https/media2.giphy.com/media/Q8bEDnj9hZd6vivXSZ/giphy.mp4")
    message.channel.send(embed)
    }
});

client.login(process.env.token)

（嵌入就是一个例子。）

尝试在

新建Discord.MessageEmbed（）之前定义Discord:
const Discord=require（'Discord.js'）
嘿，不和谐已经被定义了！关于如何解决这个问题还有其他想法吗？这意味着变量Discord已定义，但值是
未定义的
。用完整的代码（令牌除外）很容易解决
