无法在discord.py bot中重现队列

Question

我正在创建一个音乐机器人，并且正在创建队列。 我已经创建了循环来检查队列中是否有某些内容，如果有，则重现它，但是当机器人播放第二首歌曲时，我收到以下错误。

File "C:\Users\hmd4i\Desktop\BlueZoom\src\music.py", line 33, in siguiente
    self.vc.play(discord.FFmpegPCMAudio.from_probe(url2, **FFMPEG_OPTIONS), after=lambda e: self.siguiente())
AttributeError: 'str' object has no attribute 'play'.

我的代码如下：

你好，这是我的队列命令希望它可以帮助你

async def check_queue(self, ctx):
        if len(self.song_queue[ctx.guild.id]) > 0:
            ctx.voice_client.stop()
            await self.play_song(ctx, self.song_queue[ctx.guild.id][0])
            self.song_queue[ctx.guild.id].pop(0)


    @commands.command()
    @commands.cooldown(1, 5, commands.BucketType.user)
    async def queue(self, ctx):
        if await get_mute(ctx.author) != 0:
            await ctx.send("You are blacklisted from the bot")
        else: # display the current guilds queue
            commandd = "queue"
            print(f"{ctx.author.name}, {ctx.author.id} used command "+commandd+" used at ")
            print(x)
            print(" ")
            if len(self.song_queue[ctx.guild.id]) == 0:
                return await ctx.send("There are currently no songs in the queue.")

            embed = discord.Embed(title="Song Queue", description="", colour=discord.Color.green().dark_gold())
            i = 1
            for url in self.song_queue[ctx.guild.id]:
                embed.description += f"{i}) {url}\n"

                i += 1

            embed.set_footer(text="Thanks for using me!")
            await ctx.send(embed=embed)

只要删除黑名单成员就可以了
