discord.ext.commands.errors.CommandInvokeError:命令引发异常：AttributeError:“str”对象没有属性“author”

Question

我从Python开始，我正在制作一个Discord机器人几个星期，现在，当我试图在我的机器人中制作一个“投票系统”时，我遇到了如下错误：

discord.ext.commands.errors.CommandInvokeError: Command raised an exception: AttributeError: 'str' object has no attribute 'author'

我的代码：

    @client.command()
async def hlasovani(self, ctx, volba1, volba2, *, tema):
    embed = discord.Embed(title = tema,description = f":one: {volba1}\n\n:two: {volba2}",color = ctx.author.color,timestamp = datetime.datetime.utcnow())
    embed.set_footer(text = f"Hlasování zahájil {ctx.author.name}")
    embed.set_thumbnail(url = ctx.author.avatar_url)
    message = await ctx.send(embed = embed)
    await message.add_reaction("1️⃣")
    await message.add_reaction("2️⃣")
    await asyncio.sleep(5)

    newmessage = await ctx.fetch_message(message.id)
    onechoice = await newmessage.reactions[0].users().flatten()
    secchoice = await newmessage.reactions[1].users().flatten()

    vysledek = "REMÍZA!"
    if len(onechoice)>len(secchoice):
        vysledek = volba1
    elif len(secchoice)<len(onechoice):
        vysledek = volba2

    embed = discord.Embed(title = tema, description = f"Výsledek: {vysledek}", color = ctx.author.color, timestamp = datetime.datetime.utcnow())
    embed.set_footer(text = f"{volba1} || {volba2}")

    await newmessage.edit(embed = embed)

我真的很感激任何帮助

由于您使用的是@client.command()而不是@commands.command()，因此我假定您的命令不在cog或其他类中。如果是这种情况，则需要从命令中删除self参数

async def hlasovani(ctx, volba1, volba2, *, tema):
