（节点：44564）UnhandledPromiseRejectionWarning：TypeError：client.on 不是函数

Question

我目前正在使用许多不同的命令制作一个不和谐的机器人，在实现了一个 ?beg 和一个 ?bal 命令来乞求我的假想货币“比特”之后，它似乎破坏了很多代码。我能够修复所有问题，除了一个错误，它来自于输入？verify。当您键入 ?verify 时，机器人会向您发送 ?verify 的聊天发送一个嵌入，并要求成员对嵌入做出反应，并打勾以赋予“会员”角色。键入 ?verify 并按 Enter 后，会出现嵌入，并且机器人也会对自身做出反应，并带有刻度，尽管在做出反应时，成员不会获得角色。当我查看终端时，出现了这个错误，

(node:44564) UnhandledPromiseRejectionWarning: TypeError: client.on is not a function

这很奇怪，因为 client.on 是在代码顶部定义的函数。

async execute(message, client, args, Discord) {

我已经在堆栈溢出时对其进行了搜索，但只是人们说我错误地声明了“客户端”，尽管当“正确”声明客户端时，我只是收到另一个错误，说“客户端”已经定义了它是什么。

这是完整的代码，

module.exports = {
    name: 'verify',
    description: 'Allows members to react to a message to verify themselves.',
    async execute(message, client, args, Discord) {
        const channel = message.channel.id;
        const memberRole = message.guild.roles.cache.find(role => role.name === 'Member');

        const memberEmoji = '✅';
        const { MessageEmbed } = require('discord.js');

        let embed = new MessageEmbed()
            .setColor('#800080')
            .setTitle('Verification')
            .setDescription('React to this embed with the :white_check_mark: to verify yourself and gain access to the server.\n'
                + `Removing your reaction to this embed will un-verify you.`);

        let messageEmbed = await message.channel.send(embed);
        messageEmbed.react(memberEmoji);

        client.on('messageReactionAdd', async (reaction, user) => {
            if (reaction.message.partial) await reaction.message.fetch();
            if (reaction.partial) await reaction.fetch();
            if (user.bot) return;
            if (!reaction.message.guild) return;

            if (reaction.message.channel.id == channel) {
                if (reaction.emoji.name === memberEmoji) {
                    await reaction.message.guild.members.cache.get(user.id).roles.add(memberRole);
                }
            } else {
                return;
            }
        });

        client.on('messageReactionRemove', async (reaction, user) => {
            if (reaction.message.partial) await reaction.message.fetch();
            if (reaction.partial) await reaction.fetch();
            if (user.bot) return;
            if (!reaction.message.guild) return;

            if (reaction.message.channel.id == channel) {
                if (reaction.emoji.name === memberEmoji) {
                    await reaction.message.guild.members.cache.get(user.id).roles.remove(memberRole);
                }
            } else {
                return;
            }
        });
    }
}

这里是处理所有命令的 message.js，

const profileModel = require('../../models/profileSchema');

module.exports = async (Discord, client, message) => {
    const prefix = '?';
    if (!message.content.startsWith(prefix) || message.author.bot) return;

    let profileData;
    try {
        profileData = await profileModel.findOne({ userID: message.author.id });
        if(!profileData) {
            let profile = await profileModel.create({
                userID: message.author.id,
                serverID: message.guild.id,
                bits: 1000,
                bank: 0,
            });
            profile.save();
        }
    } catch (err) {
        console.log(err);
    }

    const args = message.content.slice(prefix.length).split(/ +/);
    const cmd = args.shift().toLowerCase();

    const command = client.commands.get(cmd);

    try {
        command.execute(message, args, cmd, client, Discord, profileData);
    } catch (err) {
        message.reply('There was an error executing this command.');
        console.log(err);
    }
};

Answer 1

这是一个简单的解决方法，只需找到这一行：

async execute(message, client, args, Discord)

并将其更改为

async execute(message, args, cmd, client, Discord, profileData)

问题在于 message.js command.execute(message, args, cmd, client, Discord, profileData);

执行参数 where "message, args, cmd, client, Discord, profileData" 但是在您的验证文件中，“消息，客户端，参数，不和谐”的参数 您没有在客户端之前添加“args，cmd”，因此客户端定义错误

将来可能会弄乱您的代码的另一件事！把这行const { MessageEmbed } = require('discord.js');放在最上面..
