Discord.py 当在播放命令中给出 youtube link 时，音乐机器人引发 TypeError
Discord.py music bot raising TypeError when a youtube link is given in the play command
当我在播放命令中输入 youtube url 时，我的 discord 机器人会引发 TypeError。
当我给出一个音乐名称时它会起作用，但当我给出一个 url 比如 https://youtu.be/ylVnYh-b3Qg..... 时它不起作用。
我无法理解问题出在哪里......
是在我的播放命令中还是在 MusicSource 中....
在此先感谢您的帮助。
这是我写的代码：
class MusicSource(discord.PCMVolumeTransformer):
youtube_dl.utils.bug_reports_message = lambda: '' # Suppressing Random Youtube_Dl warnings
ytdl_format_options = { # options for the youtube_dl module, for the audio quality
'format': 'bestaudio/best',

# (Enabling it sometimes makes the bot not play anything)
}
ytdl = youtube_dl.YoutubeDL(ytdl_format_options) # Sending the options to the Youtube_DL class
def __init__(self, source: discord.AudioSource, *, data):
self.volume = 0.4
super().__init__(source, self.volume)

@classmethod

# audio from the url
ffmpeg_options = {

'options': f'-vn -ss {timestamp}'
}
loop = loop or asyncio.get_event_loop()
data = await loop.run_in_executor(None, lambda: cls.ytdl.extract_info(url, download=not stream))
if 'entries' in data:

filename = data['url'] if stream else cls.ytdl.prepare_filename(data)
return cls(discord.FFmpegPCMAudio(filename, **ffmpeg_options), data=data)
以及加入和播放命令：
