您可以简单地对视图类进行这些更改以禁用这两个按钮

class MyView(View):
  # do what you just did
  @button(label="Hello!", style=discord.ButtonStyle.blurple)
  async def hello(self, interaction: discord.Interaction, button: Button):
    # do sth
    # example to disable both buttons by clicking 'hello' button
    button.disabled = True  # disable the 'hello' button
    bye_btn = discord.utils.get(self.children, label="No. Bye.")  # get the 'bye' button
    bye_btn.disabled = True
    # send a msg or sth else

如果您想删除所有按钮，这甚至比禁用按钮更容易

class MyView(View):
  @button(label="Hello!", style=discord.ButtonStyle.blurple)
  async def hello(self, interaction: discord.Interaction, button: Button):
    # do sth
    await interaction.response.edit_message(view=None)  # this will remove all the components in the class

我建议你稍微修改一下斜线命令

@client.hybrid_command(name="hello", description="Say hello to the bot!")
async def hello(ctx):
    # do your embed stuff
    # the good way to do this is that you could access your message (in your view class) by 'self.message'
    # because functions like 'on_timeout' does not have 'interaction' param.
    view = MyView()
    view.message = await ctx.send(embed=embedHello, view=view)

并且作为一个快速的提醒，你只能对交互进行一次响应，以避免触发交互响应异常。因此，如果您想发送消息并编辑视图，则可以切换到followup

class MyView(View):
  @button(label="Hello!", style=discord.ButtonStyle.blurple)
  async def hello(self, interaction: discord.Interaction, button: Button):
    await interaction.response.defer()
    # do sth
    await interaction.followup.send(content='...', ...)  # send the message you want
    await interaction.followup.edit_message(message_id=self.message.id, view=None)  # message_id is mandatory here

希望这能帮上忙。
