Question

所以我使用这个音乐播放器 https://github.com/Rapptz/discord.py/blob/master/examples/basic_voice.py 因为我自己的太慢了，它工作得很好，但昨天我注意到它不再工作了，我使用了我自己的版本，所以我只是尝试使用普通版本，它没有工作太多任何想法为什么？有时也停止或加入不起作用。谢谢！

可能是你没有在你的机器人上安装语音支持，我不确定但它应该提到安装某个包；

-pip install discord.py[voice]

如果您正在使用 repl.it（在这种情况下很有可能），那么您必须不断安装它，因为没有导入命令并且 repl.it 实际上并没有安装软件包，（或者有那么多用户，repl.it 可能会崩溃）它只是读取它们。如果您打算制作音乐机器人，我建议您找一个合适的主机。

在您的情况下，repl.it 可能在您离开时关闭（或 repl.it 重新启动）并且软件包未安装因此无法工作。

希望这能回答您的问题，如果您有任何其他问题，请提问！
