Question

我正在尝试将播放命令添加到我的Discord机器人中，以便它以后可以播放youtube和其他地方的音乐，但现在我只是尝试让它从计算机上播放音频文件以测试是否可以播放它会加入并播放一些东西，然后再进入更复杂的内容，例如弄清楚如何从youtube url播放歌曲/音频

现在，这就是我所拥有的

Crashbot.on('message', async message => {

    let args = message.content.substring(PREFIX.length).split(" ");

    switch (args[0]) {
        case 'play':
            if (message.member.voice.channel) {
                const connection = await message.member.voice.channel.join().then(() => {

                    const dispatcher = connection.play('audio.mp3');

                    dispatcher.on('start', () => {

                    });

                    dispatcher.on('error', console.error);

                })
            }
    }

})

每次运行它都会出现此错误

尝试删除.then(...)。由于存在await，因此在没有.then()的情况下运行良好。在您的代码中，connection是承诺的返回值。因此会引发错误。

尝试以下代码：

const connection = await message.member.voice.channel.join();

const dispatcher = connection.play('audio.mp3');

dispatcher.on('start', () => {});

dispatcher.on('error', console.error);
