我正在使用Heroku来托管我的应用,我有以下代码:
if (isReady && message.content === '!play')
{
isReady = false;
var voiceChannel = message.member.voiceChannel;
voiceChannel.join().then(connection =>
{
const dispatcher = connection.playFile('./BRODYQUEST.mp3');
dispatcher.on("end", end => {
voiceChannel.leave();
});
}).catch(err => console.log(err));
isReady = true;
}
当我输入命令时,机器人加入我的频道,但它不播放任何音乐。我在控制台中收到此错误:

答案 0 :(得分:1)
要运行此程序,您需要安装ytdl-core
。
npm install --save ytdl-core
如果收到显示“ OPUS_ENGINE_MISSING”的错误,则需要安装discord.js建议的其中一个软件包。
npm install --save node-opus
如果出现“找不到FFMPEG”错误,则可以通过安装ffmpeg来解决。
在Debian / Ubuntu上:
sudo apt-get install ffmpeg
在Windows上:
npm install ffmpeg-binaries --save
另外,有报道称,无法从Windows 10提供的Ubuntu子系统中以这种方式播放音频。

所以你已经成功安装了discord.js
但是要解码和编码你想要播放的mp3文件,你必须安装一个编解码器来为你做这件事:
所以你只需安装npm install discord.js node-opus
就可以了。
