第一件小事，tree.remove_command(command)就是not.

无论如何，你真正想做的是禁用命令无论如何，

How to create a disable command in discord.py

判断是否存在

tree.get_commands个退货:

List[Union[ContextMenu, Command, Group]]

这意味着，如果你想具体判断Command，你必须解析它.command参数也是一个字符串，这就是为什么它最初没有返回true的原因.但是，我们可以在命令树中使用一个更简单的命令.

应该怎么做

tree.get_command(单数不复数)返回:

Optional[Union[Command, ContextMenu, Group]]

是的，这是一回事.但是，参数是不同的.

命令(Str)-要获取的根命令的名称.

行会(可选[snowflake])-要获得命令的行会.如果未给出或无，则它将获得一个全局命令.

type(AppCommandType)—要获取的命令类型.切换到chat_input，即斜杠命令.

您可以将之前的command字符串参数传入此命令.然后你可以判断它是否返回任何东西.这比解析快得多(如前所述).您也不会判断是否存在多个命令，因此这是最佳 Select .

下面我有一个代码示例(作为参考，我之前做了另一个命令):

@tree.command(guild=discord.Object(id=guild_id), name='disable', description='Disable a specified Command')
async def disable(interaction: discord.Interaction, command: str):
    if tree.get_command(command, guild=discord.Object(id=guild_id)):
        tree.remove_command(command, guild=discord.Object(id=guild_id))  # remove the command
        await interaction.response.send_message(
            f"{command} was disabled. You can reenable it by running /enable {command}")
    else:
        await interaction.response.send_message(f"Command could not be found: {command}")

禁用命令

但是，这实际上并不会禁用该命令.这是为什么？如果是tree.remove_command，则需要同步树.只需添加一行:

await tree.sync(guild=discord.Object(id=guild_id))

它应该会奏效的！

完整代码:

@tree.command(guild=discord.Object(id=guild_id), name='disable', description='Disable a specified Command')
async def disable(interaction: discord.Interaction, command: str):
    await interaction.response.defer()
    if tree.get_command(command, guild=discord.Object(id=guild_id)):  # check if the command exists
        tree.remove_command(command, guild=discord.Object(id=guild_id))  # remove the command
        print("command removed!")
        await tree.sync(guild=discord.Object(id=guild_id))  # sync the tree
        print("tree synced!")
        await interaction.followup.send(
            f"{command} was disabled. You can reenable it by running /enable {command}")
    else:
        await interaction.followup.send(f"Command could not be found: {command}")

Tested this locally & the slash command say doesn't appear anymore. It's also gone from integrations:
