“ TypeError：无法读取未定义的属性'push'” discord.js

Question

我有这个完整的错误：

 (node:9352) UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'push' of undefined at Object.exports.run (C:\\users\\Cocoloco2005\\Desktop\\peterbot\\commands\\play.js:24:16) at processTicksAndRejections (internal/process/next_tick.js:81:5) (node:9352) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). (rejection id: 1) (node:9352) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code. 

这是我在“播放”命令中使用Discord.js创建Discord机器人时发生的一个问题

（完整命令在这里：

 const ytdl = require('ytdl-core'); exports.run = async (client, message, args, ops) => { if (!message.member.voiceChannel) return message.channel.send('Connectes toi à un salon vocal'); if (!args[0]) return message.channel.send('Entres une URL'); let validate = await ytdl.validateURL(args[0]); if (!validate) { let commandFile = require('./search.js'); return commandFile.run(client, message, args, ops); } let info = await ytdl.getInfo(args[0]); let data = ops.active = (message.guild.id) || {}; if (!data.connection) data.connection = await message.member.voiceChannel.join(); if(!data.queue) data.queue = []; data.guildID = message.guild.id; data.queue.push[0]({ songTitle: info.title, requester: message.author.tag, url: args[0], announceChannel: message.channel.id }); if (!data.dispatcher) play(client, ops, data); else { message.channel.send(`Added to queue: ${info.title} | requested by: ${message.author.id}`) } ops.active.set(message.guild.id, data); } async function play(client, ops, data) { client.channels.get(data.queue[0].announceChannel).send(`Now Playing: ${data.queue[0].songTitle} | Requested by: ${data.queue[0].requester}`); data.dispatcher = await data.connection.playStream(ytdl(data.queue[0].url, {filter: 'audioonly'})); data.dispatcher.guildID = data.guildID; data.dispatcher.once('end', function() { end(client, ops, this); }); } function end(client, ops, dispatcher){ let fetched = ops.active.get(dispatcher.guildID); fetched.queue.shift(); if (fetched.queue.length > 0) { ops.active.set(dispatcher.guildID, fetched); play(client, ops, fetched); } else { ops.active.delete(dispatcher.guildID); let vc = client.guilds.get(dispatcher.guildID).me.voiceChannel; if (vc) vc.leave(); } } 

我不知道该怎么做，我没有尝试任何“特别的”操作，因为我是Java语言的新手。 我尝试搜索，但没有发现任何有关我的错误的信息。

Answer 1

您的错误在以下代码段中：

data.queue.push[0]({
    songTitle: info.title,
    requester: message.author.tag,
    url: args[0],
    announceChannel: message.channel.id

});

除非push是queue的可索引属性，否则第一行可能是问题。 在我看来，您可能不小心添加了[0] ，因为如果没有它，这将是一个有效的声明。 我希望这有帮助！
