NextCord:在斜杠命令中使用转换器出错

Question

我有discord.py和pycord的背景，我决定尝试nextcord斜杠命令所以我决定创建一些命令，在这个命令中我得到了一个奇怪的错误消息

@slash_command(name='suggestions_set', guild_ids=[956174862815199252])
async def suggestions_set(self, interaction: Interaction, channel: TextChannel):
db.insert({'channel': channel.id})
await interaction.send(f'**The suggestions channel has been set to {channel.mention}**')

我得到了以下错误:

Traceback (most recent call last):

raise NotImplementedError(
NotImplementedError: Type "<class 'nextcord.application_command.SlashOption'>" isn't a supported typing for Application Commands.
The above exception was the direct cause of the following exception:
Traceback (most recent call last):
File "C:UsersangelCodePythonspybotbot.py", line 19, in <module>
bot.load_extension(f'cogs.{file[:-3]}')

nextcord.ext.commands.errors.ExtensionFailed: Extension 'cogs.info' raised an error: NotImplementedError: Type "<class 'nextcord.application_command.SlashOption'>" isn't a supported typing for Application Commands.

我明白这一定是一些类型的实现错误，但我不明白它，如果有人能告诉我做错了什么?

Answer 1

channel: TextChannel = SlashOption(...)应该根据其github存储库中的示例工作。
