尝试在未经禁止权限的情况下禁止用户时发生错误

Question

我得到：

discord.ext.commands.errors.CommandInvokeError: Command raised an exception: TypeError: ban_error() takes 2 positional arguments but 3 were given

每当我尝试使用这个命令时： （我正在使用齿轮）

@commands.command(name="ban", pass_context=True)
@has_permissions(ban_members=True)
async def _ban(self, ctx, member : discord.Member = None, *, reason:str = None):
    if member == None:
        await ctx.send("Please mention a user.")
    if reason == None:
        reason = "N/A"
    else:
        ban=discord.Embed(title=f"You have been banned from {ctx.guild.name}", color=0x61187c)
        ban.add_field(name="Reason:", value=f"{reason}", inline=True)
        ban.set_footer(text="( ͡° ͜ʖ ͡°)")
        await member.send(embed=ban)
        embed=discord.Embed(title=f"Successfully Banned {member}", color=0x61187c)
        embed.add_field(name="Reason:", value=f"{reason}", inline=True)
        embed.set_footer(text="( ͡° ͜ʖ ͡°)")
        await ctx.send(embed=embed)
        await member.ban(reason=reason)

@_ban.error
async def ban_error(error, ctx):
    if isinstance(error, MissingPermissions):
        channel = message.channel
        text = "Sorry {}, you do not have permissions to do that!".format(ctx.message.author)
        await channel.send(text)

我很确定这是因为我的原因，但我不确定。

discord.ext.commands.errors.CommandInvokeError: Command raised an exception: TypeError: ban_error() takes 2 positional arguments but 3 were given

错误不言而喻。

您应该尝试为 async def ban_error 实现 3 个参数（您不必全部使用它们，只需确保其中有 3 个，因为库提供了 3 个参数。
