【问题描述】：

现在，我正在尝试制作一个反应角色机器人，但我不断收到错误消息。这是我的代码。

const Discord = require('discord.js');
const keepAlive = require('./server');
const client = new Discord.Client();

client.on('message', message => 
    if (message.author !== null && message.author.bot) return;
    if (message.toString().toLowerCase().includes('start reaction roles')) 
        message.delete()
        const embed = new Discord.MessageEmbed()
            .setColor('#0099ff')
            .setTitle('React to get notified')
            .setDescription(`Hello! Please react to this message to get a role. Here are the roles that you can get by reacting:\n> ???? | React with this emoji to get <@&727665971443269635> notifications.\n> ⚠️ | React with this emoji to get <@&727633811709362187>.\nYou can chose one of the emojis, or both of them.`)
        message.channel.send(embed).then(sentMessage => 
            sentMessage.react("????")
            .then(() => sentMessage.react("⚠️"))
            .catch(() => console.error('One of the emojis failed to react.'));
        )
        const collector = sentMessage.createReactionCollector();
        collector.on('collect', (reaction, user) => 
            if (reaction.emoji.name === '????')
                role = message.guild.roles.find(role => role.name === "ne1 here");
                message.member.addRole(role);
            
            else if (reaction.emoji.name === '⚠️')
                role = message.guild.roles.find(role => role.name === "HR notifications");
                message.member.addRole(role);
            
        )
    
);

keepAlive();
client.login(process.env.TOKEN);

上面写着const collector = sentMessage.createReactionCollector(); 的部分不起作用。如果有人可以帮我解决这个问题，那就太好了。

【参考方案1】：

我刚刚想出了如何让它运行。如果您想使用它，这是代码（这是我的全部代码。如果需要，请删除一些部分）。

const Discord = require('discord.js');
const keepAlive = require('./server');
const client = new Discord.Client();

client.on('message', message => 
    if (message.author !== null && message.author.bot) return;
    if (message.toString().toLowerCase().includes('start reaction roles')) 
        message.delete()
        const embed = new Discord.MessageEmbed()
            .setColor('#0099ff')
            .setTitle('React to get notified')
            .setDescription(`Hello! Please react to this message to get a role. Here are the roles that you can get by reacting:\n> ? | React with this emoji to get <@&727665971443269635> notifications.\n> ⚠️ | React with this emoji to get <@&727633811709362187>.\nYou can chose one of the emojis, or both of them.\n\n**NOTE:**\nCurrently, this command does not support removing your roles. If you want to remove your role, click on the emoji. Then, click on your profile, and click the X next to the role you want to remove. You can always get it back by reacting.`)
        message.channel.send(embed).then(sentMessage => 
            sentMessage.react("?").then(() => sentMessage.react("⚠️")).then(() => 
                const filter = (reaction, user) => 
                    return true;
                
                const collector = sentMessage.createReactionCollector(filter);
                collector.on('collect', (reaction, user) => 
                    if (reaction.emoji.name === '?')
                        role = message.guild.roles.cache.find(role => role.name === "ne1 here");
                        message.member.roles.add(role);
                    
                    else if (reaction.emoji.name === '⚠️')
                        role = message.guild.roles.cache.find(role => role.name === "HR notifications");
                        message.member.roles.add(role);
                    
                )
            )
            .catch(() => console.error('One of the emojis failed to react.'));
        )
    
);

keepAlive();
client.login(process.env.TOKEN);

我希望这是有用的。
