【问题描述】：

我正在尝试制作一个不和谐机器人，当被调用时，它会加入作者所在的语音频道。

这是我所拥有的：

@client.command(aliases=["join"])
async def join_voice(self, ctx):
    channel = ctx.author.voice.channel
    if channel:
        print(channel.id)
        await channel.connect()

当我加入语音频道并输入命令时，我收到此错误：

Ignoring exception in command join_voice:
Traceback (most recent call last):
  File "C:\Users\User\AppData\Local\Programs\Python\Python37-32\lib\site-packages\discord\ext\commands\bot.py", line 892, in invoke
    await ctx.command.invoke(ctx)
  File "C:\Users\User\AppData\Local\Programs\Python\Python37-32\lib\site-packages\discord\ext\commands\core.py", line 790, in invoke
    await self.prepare(ctx)
  File "C:\Users\User\AppData\Local\Programs\Python\Python37-32\lib\site-packages\discord\ext\commands\core.py", line 751, in prepare
    await self._parse_arguments(ctx)
  File "C:\Users\User\AppData\Local\Programs\Python\Python37-32\lib\site-packages\discord\ext\commands\core.py", line 670, in _parse_arguments
    transformed = await self.transform(ctx, param)
  File "C:\Users\User\AppData\Local\Programs\Python\Python37-32\lib\site-packages\discord\ext\commands\core.py", line 516, in transform
    raise MissingRequiredArgument(param)
discord.ext.commands.errors.MissingRequiredArgument: ctx is a required argument that is missing.

【解决方案1】：

此命令是否位于 cog/extension 中？看起来上下文是作为 self 传递的，仅当函数是类函数时才需要。如果您在主文件中声明此命令，您只需将签名设为 async def join_voice(ctx):
