Question

这是我的 index.js 并且我收到此错误（UnhandledPromiseRejectionWarning：TypeError：无法读取未定义的属性“播放”），你能帮我吗？

const Discord = require("discord.js"),
client = new Discord.Client(),
settings = {
    prefix: "=",
    token: "(my bot's token)"
};
 
const { Player } = require("discord-player");
const player = new Player(client);
client.player = player;
client.player.on('trackStart', (message, track) => message.channel.send(`Now playing ${track.title}...`))
 
client.on("ready", () => {
    console.log("I'm ready !");
});

client.on("message", async (message) => {
 
    const args = message.content.slice(settings.prefix.length).trim().split(/ +/g);
    const command = args.shift().toLowerCase();

 if (command === "play") {
     let track = await client.Player.play(member.voice.channel, args[0], message.member.user.tag);
     message.channel.send(`Currently playing ${track.name}! - Requested by ${track.requestedBy}`);
 }
});
client.login(settings.token);

请记住，JavaScript 变量名称区分大小写。比较您示例中的以下几行：

client.player = player;
let track = await client.Player.play();

尝试将您的呼叫更改为 client.player 而不是 client.Player。

您甚至可能想将 player 重命名为 currentPlayer 或其他名称，以区分 player（一个实例）和 Player（一个类）。
