Heroku上托管的Python Discord Bot不播放音频

Question

我正在构建类似音乐机器人的东西，我决定在heroku上主持它。不幸的是，它不能正常工作。一切正常，机器人连接到一个语音频道，但我听不到机器人播放的任何音频。昨天我收到一个错误（来自heroku的日志）：

2020-08-06T15:13:45.003027+00:00 app[worker.1]: Ignoring exception in on_ready
2020-08-06T15:13:45.004547+00:00 app[worker.1]: Traceback (most recent call last):

2020-08-06T15:13:45.004672+00:00 app[worker.1]: discord.opus.OpusNotLoaded

但今天我以某种方式修复了它，并且没有收到任何错误消息，但是音频仍然无法从bot播放。它看起来像这样：

2020-08-06T15:27:50.232782+00:00 app[worker.1]: [youtube] 1dOt_VcbgyA: Downloading webpage

然后它就停止了（当我在电脑上运行时，一切正常。）

“根据discord.py文档，您不应该在windows环境中使用它，这可能就是为什么它在本地计算机上工作，而不是在heroku（基于unix）上工作的原因。”
