带有 youtube dl 的不和谐机器人音乐不会卡在网页下载中

【中文标题】带有 youtube dl 的不和谐机器人音乐不会卡在网页下载中

【英文标题】：discord bot music with youtube dl not stuck at webpage downloading

【问题描述】：

所以我正在尝试制作一个音乐机器人，它可以加入、播放、停止和恢复音乐。但是，我的机器人可以正常加入并离开语音频道，但是当我执行 /play 命令时，它会卡在[youtube] oCveByMXd_0: Downloading webpage 上（这是在 vscode 中的输出），然后什么也不做。我放了一些打印语句（您可以在下面的代码中看到它打印 1 和 2 但不是 3）。有人遇到过这个问题吗？

这就是我的播放音乐命令的设置方式，我确信它可以工作，而且它似乎也应该适合你。

@commands.command()
    async def play(self, ctx, *, song=None):
            commandd = "play"
            print(f"ctx.author.name, ctx.author.id used command "+commandd+" used at ")
            print(x)
            print(" ")
            if song is None:
                return await ctx.send("You must include a song to play.")

            if ctx.voice_client is None:
                return await ctx.send("I must be in a voice channel to play a song.")

            # handle song where song isn't url
            if not ("youtube.com/watch?" in song or "https://youtu.be/" in song):
                await ctx.send("Searching for song, this may take a few seconds.")

                result = await self.search_song(1, song, get_url=True)

                if result is None:
                    return await ctx.send("Sorry, I could not find the given song, try using my search command.")

                song = result[0]

            if ctx.voice_client.source is not None:
                queue_len = len(self.song_queue[ctx.guild.id])

                if queue_len < 10:
                    self.song_queue[ctx.guild.id].append(song)
                    return await ctx.send(f"I am currently playing a song, this song has been added to the queue at position: queue_len+1.")

                else:
                    return await ctx.send("Sorry, I can only queue up to 10 songs, please wait for the current song to finish.")

            await self.play_song(ctx, song)
            await ctx.send(f"Now playing: song")
