javascript - Discord 欢迎消息：无法读取未定义的属性“MessageEmbed”

Question

我正在尝试嵌入基本的欢迎信息。这是我main.js减去登录令牌：

const Discord = require('discord.js');
const client = new Discord.Client();
const MessageEmbed = new Discord.MessageEmbed();

const prefix = 'm.';
const fs = require('fs');

client.commands = new Discord.Collection();
client.events = new Discord.Collection();

const eventFiles = fs.readdirSync('./events').filter(file => file.endsWith('.js'));
for (const file of eventFiles) {
    const event = require(`./events/${file}`);
    if (event.once) {
        client.once(event.name, (...args) => event.execute(...args));
    } else {
        client.on(event.name, (...args) => event.execute(...args));
    }
}

这是welcome.js减去 的定义channelId：

module.exports = {
    name: 'guildMemberAdd', 
    execute(member, Discord) {

        console.log('login');

        const message = `Welcome <@${member.id}> !`;
        const channel = member.guild.channels.cache.get(channelId);

        const joinEmbed = new Discord.MessageEmbed()
            .setTitle(`New member!`)
            .setDescription(message)
            .setColor("#fab9c7");
        
        channel.send({ joinEmbed });
     },
};

这是完整的错误消息：

        const joinEmbed = new Discord.MessageEmbed()
                                      ^

抱歉，如果这真的很基本，我对 javascript 还不是很满意。我似乎无法理解模块语法。

Answer 1

Discord在您的模块中未定义。这是因为guildMemberAdd事件的回调函数只有一个参数，即GuildMember.

只需在你的模块中引入 discord.js，或者在调用时传入 Discordexecute
