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机器人时遇到的问题

（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。我尝试进行搜索，但没有发现任何有关我的错误的人的信息。

您的错误在此块中：

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所在。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。我希望这会有所帮助！
