Discord.js V12 消息收集器“错误”？

Question

我正在创建一个名册命令，这是我到目前为止的代码，错误是当涉及到管理员时，它会像图片中一样出现错误并且它不会继续......它还保存了所有答案在一个文件中。 因此管理员执行$roster setup 并开始保存每个文件名称的回复。这是我目前唯一完成的部分，所以设置。我在那里遇到了那个错误，控制台中没有错误。

client.on('message', async message => {
    if (message.content.startsWith(prefix + "roster")) {
    if (!message.member.hasPermission('ADMINISTRATOR')) return message.channel.send('You do not have that permission! :x:').then(message.react(':x:'))
    if (message.author.bot){}
        else {
            !fs.existsSync(`./roster/` + message.guild.id) && fs.mkdirSync(`./roster/` + message.guild.id, { recursive: true })
            const args = message.content.slice(prefix.length + 7).split(/ +/)
            let uReply = args[0];
            if(!uReply) return message.channel.send("Please use the following options: `setup`, `send`, `add` or `remove`!")

            //SETUP
            if(uReply === "setup") {
                const collector = new Discord.MessageCollector(message.channel, m => m.author.id === message.author.id, { time: 10000 });
            
                message.channel.send("Please write the exact role name of leader role (with emojis if it has).")
                collector.on('collect', message => {
                    let leaderRole = message.content
                    fs.writeFileSync(`./roster/${message.guild.id}/`+ `Leader`+".txt", message.content, (err) => console.error);
                    message.channel.send(`Ok, the leader role is called \`${leaderRole}\`.`) 
                    collector.off
                

                message.channel.send("Now, whats the role name of co-leader or co-owner role (with emojis if it has)?")
                collector.on('collect', message => {
                    let coleaderRole = message.content
                    fs.writeFileSync(`./roster/${message.guild.id}/`+ `Co-Leader`+".txt", message.content, (err) => console.error);
                    message.channel.send(`Ok, the co-leader/co-owner role is called \`${coleaderRole}\`.`) 
                    collector.off


                message.channel.send("Now, whats the role name of admin role (with emojis if it has)?")
                collector.on('collect', message => {
                    let adminRole = message.content
                    fs.writeFileSync(`./roster/${message.guild.id}/`+ `Admin`+".txt", message.content, (err) => console.error);
                    message.channel.send(`Ok, the admin role is called \`${adminRole}\`.`) 
                    collector.off
 

                message.channel.send("Awesome, now whats the role name of staff role (with emojis if it has)?")
                collector.on('collect', message => {

                    collector.off


                message.channel.send("Cool, now whats the role name of tiny-staff role (with emojis if it has)?")
                collector.on('collect', message => {

                    message.channel.send(`Ok, the tiny-staff role is called \`${tinyStaffRole}\`.`)
                    collector.off


                message.channel.send("Just a few more, now whats the role name of higher ranked members role (with emojis if it has)?")
                collector.on('collect', message => {

我认为错误来自原始 MessageCollector 侦听器未正确禁用，因此原始侦听器仍会为每条附加消息触发。

看起来您试图用collector.off 停止原始侦听器，但因为这是一个语句而不是函数调用，所以它什么也没做。此外，如果它确实起作用了，它将结束父收集器，并且后续的 collector.on 回调都不会起作用。

相反，我会将 collector.on 函数替换为 collector.once 并删除 collector.off 语句。将其更改为collector.once 会在侦听器接收到第一个事件后自动结束它，这就是您在这种情况下想要的。如果您想接收多个事件，则必须使用其他东西。

例如，监听器看起来像这样：

collector.once('collect', message => {
    let leaderRole = message.content
    fs.writeFileSync(`./roster/${message.guild.id}/`+ `Leader`+".txt", message.content, (err) => console.error);
    message.channel.send(`Ok, the leader role is called \`${leaderRole}\`.`)

    /* ... Rest of code ... */
