Discord.js V12 消息收集器“錯誤”？

Question

我正在制作一個名冊命令，這是我到目前為止的代碼，錯誤是當涉及到管理員時，它會像圖片中一樣出現錯誤並且它不會繼續......它還將所有答案保存在一個文件中. 因此，管理員進行$roster setup並開始保存每個文件名稱的回復。 這是我目前唯一完成的部分，所以設置。 我在那里遇到了那個錯誤，控制台中沒有錯誤。

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 => {
                    let staffRole = message.content
                    fs.writeFileSync(`./roster/${message.guild.id}/`+ `Staff`+".txt", message.content, (err) => console.error);
                    message.channel.send(`Ok, the staff role is called \`${staffRole}\`.`)
                    collector.off


                message.channel.send("Cool, now whats the role name of tiny-staff role (with emojis if it has)?")
                collector.on('collect', message => {
                    let tinyStaffRole = message.content
                    fs.writeFileSync(`./roster/${message.guild.id}/`+ `Tiny-Staff`+".txt", message.content, (err) => console.error);
                    message.channel.send(`Ok, the tiny-staff role is called \`${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 => {
                    let HigherRankedRole = message.content
                    fs.writeFileSync(`./roster/${message.guild.id}/`+ `HigherRanked`+".txt", message.content, (err) => console.error);
                    message.channel.send(`Ok, the higher ranked members role is called \`${HigherRankedRole}\`.`)
                    collector.off


                message.channel.send("Last one, whats the role name of the normal members role (with emojis if it has)?")
                collector.on('collect', message => {
                    let NormalMembersRole = message.content

                    message.channel.send(`Awesome, the normal members role is called \`${NormalMembersRole}\`.`)
                    message.channel.send("That's it for setup.")
                    collector.off


                })})})})})})})





            }
            
        }

我相信錯誤來自原始 MessageCollector 偵聽器未正確禁用，因此原始偵聽器仍會為每條附加消息觸發。

看起來您試圖用collector.off停止原始偵聽器，但因為這是一個語句而不是 function 調用，所以它什么也沒做。 此外，如果它執行 function，它將結束父收集器，並且后續的collector.on回調將不起作用。

相反，我會用collector.once替換collector.on函數並刪除collector.off語句。 將其更改為collector.once會在接收到第一個事件后自動結束偵聽器，這就是您在本場景中想要的。 如果您想接收多個事件，則必須使用其他東西。

例如，監聽器看起來像這樣：

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 ... */
