discord.py问题与Youtube-DL，现在正在工作。知道解决办法吗？

Question

我在python中编码了我的不和谐的bot，它不起作用，我使用大树苗作为主机托管我的bot。

误差

下面的错误是join命令。

我正在使用Python3.8.5和PIP 20.3。如果你能帮忙的话，请帮我！

Answer 1

您的cog命令需要使用@commands.command而不是@client.command。

示例：

@client.command()
async def join(self, ctx, *, channel: discord.VoiceChannel):
        """Joins a voice channel"""

        if ctx.voice_client is not None:
            return await ctx.voice_client.move_to(channel)

        await channel.connect()

应：

@commands.command() # This changed...
async def join(self, ctx, *, channel: discord.VoiceChannel):
        """Joins a voice channel"""

        if ctx.voice_client is not None:
            return await ctx.voice_client.move_to(channel)

        await channel.connect()

记住，只在齿轮上这样做！
