Discord.py 尝试创建私人频道时出错

Question

我想在用户运行一个简单的命令时创建一个私人频道。代码如下：

@client.command(name='start')
async def createChannel(ctx):
    guild = ctx.guild
    member = ctx.author
    admin_role = get(guild.roles, name = "Admin")
    overwrites = {
        guild.default_role: discord.PermissionOverwrite(read_messages=False),
        member: discord.PermissionOverwrite(read_messages=True),
        admin_role: discord.PermissionOverwrite(read_messages=True)
    }
    try:
        channel = await guild.create_text_channel('{}_sentinel'.format(ctx.author), overwrites=overwrites)
    except:
        print("Error")

完整追溯：

Ignoring exception in command start:
Traceback (most recent call last):
  File "/Users/raveeshyadav/Raveesh/sentinel/sentinel/lib/python3.9/site-packages/discord/ext/commands/core.py", line 85, in wrapped
    ret = await coro(*args, **kwargs)
  File "/Users/raveeshyadav/Raveesh/sentinel/bot.py", line 44, in createChannel
    channel = await guild.create_text_channel('{}_sentinel'.format(ctx.author), overwrites=overwrites)
  File "/Users/raveeshyadav/Raveesh/sentinel/sentinel/lib/python3.9/site-packages/discord/guild.py", line 948, in create_text_channel
    data = await self._create_channel(name, overwrites, ChannelType.text, category, reason=reason, **options)
  File "/Users/raveeshyadav/Raveesh/sentinel/sentinel/lib/python3.9/site-packages/discord/guild.py", line 844, in _create_channel
    'id': target.id
AttributeError: 'NoneType' object has no attribute 'id'

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "/Users/raveeshyadav/Raveesh/sentinel/sentinel/lib/python3.9/site-packages/discord/ext/commands/bot.py", line 939, in invoke
    await ctx.command.invoke(ctx)
  File "/Users/raveeshyadav/Raveesh/sentinel/sentinel/lib/python3.9/site-packages/discord/ext/commands/core.py", line 863, in invoke
    await injected(*ctx.args, **ctx.kwargs)
  File "/Users/raveeshyadav/Raveesh/sentinel/sentinel/lib/python3.9/site-packages/discord/ext/commands/core.py", line 94, in wrapped
    raise CommandInvokeError(exc) from exc
discord.ext.commands.errors.CommandInvokeError: Command raised an exception: AttributeError: 'NoneType' object has no attribute 'id'

Answer 1

此错误是通过在 overwrites 中传递值为 None 的键而产生的。大概是admin_role。您可以查看：

您实际上在公会中有一个名为 Admin 的角色；
您已激活公会意向，您可以获得角色列表。
