Discord.py 终生无法设置斜杠命令

Question

Whenever I attempt to make a slash command in discord.py, the commands never work or even show up no matter how many times I sync them.

Here is a snip of the code for the slash command I wish to add `

@app_commands.command(name='clearnono', description="Cleaw the numbew of nono messages you want to wemove.")
@app_commands.rename(num='quantity')
@app_commands.describe(num='How many?')
async def clear(interaction: discord.Interaction, num: int):
  await interaction.channel.purge(limit=num)
  await interaction.response.send_message(f"{num} messages were cleawed swccessfwlly.", ephemeral=True)

And this is the code I use to sync the commands `

@bot.command()
@commands.guild_only()
@commands.is_owner()
async def sync(
  ctx: Context, guilds: Greedy[discord.Object], spec: Optional[Literal["~", "*", "^"]] = None) -> None:
    if not guilds:
        if spec == "~":
            synced = await ctx.bot.tree.sync(guild=ctx.guild)
        elif spec == "*":
            ctx.bot.tree.copy_global_to(guild=ctx.guild)
            synced = await ctx.bot.tree.sync(guild=ctx.guild)
        elif spec == "^":
            ctx.bot.tree.clear_commands(guild=ctx.guild)
            await ctx.bot.tree.sync(guild=ctx.guild)
            synced = []
        else:
            synced = await ctx.bot.tree.sync()

        await ctx.send(
            f"Synced {len(synced)} commands {'globally' if spec is None else 'to the current guild.'}"
        )
        return

    ret = 0
    for guild in guilds:
        try:
            await ctx.bot.tree.sync(guild=guild)
        except discord.HTTPException:
            pass
        else:
            ret += 1

    await ctx.send(f"Synced the tree to {ret}/{len(guilds)}.")

Expectation: The command is added to the bot, and I am able to use the slash command to clear messages

What actually happens: The command does not work or even show up when attempting to use it in the bot, despire the normal non-slash commands working just fine.

Did you invite your bot with the correct permissions? Bots need to be invited with the applications.commands scope in addition to the bot scope. For example, invite the bot with the following URL: https://discord.com/oauth2/authorize?client_id=1234567890&scope=applications.commands+bot
