Discord Bot Python 3.6 导入命令时出错

Question

import discord
from discord.ext.commands import commands,has_permissions, MissingPermissions
import json

with open('reports.json', encoding='utf-8') as f:
  try:
    report = json.load(f)
  except ValueError:
    report = {}
    report['users'] = []

client = discord.ext.commands.Bot(command_prefix = '?')

当我运行它时，它来了。如果我从discord.ext import commands,has_permissions, MissingPermissions 给，那么这个来ImportError: cannot import name 'has_permissions'

Traceback (most recent call last):
  File "F:\Rubayet\Discord Bots\Discord.py\Test.Bot\Test.Bot.py", line 2, in <module>
    from discord.ext.commands import commands,has_permissions, MissingPermissions
ImportError: cannot import name 'commands'

我不知道为什么。请帮我解决这个问题。

Answer 1

MissingPermissions 仅在重写分支中可用。如果没有，需要卸载discord.py然后运行

pip install -U git+https://github.com/Rapptz/discord.py@rewrite#egg=discord.py[voice]

然后您可以重新组织您的导入。导入commands 并通过该导入引用所有内容，或者导入您单独使用的所有内容。不要两者都做。

from discord.ext import commands

bot = commands.Bot(command_prefix='!')

@bot.command()
@commands.has_permissions(...)
...

或

from discord.ext.commands import Bot, has_permissions

bot = Bot(command_prefix='!')

@bot.command()
@has_permissions()
...

Answer 2

我假设您正在使用Rapptz/Discord.py 您无法从命令文件夹中导入命令。没有这种事。

我相信您正在寻找core 类的has_permissions 方法：

from discord.ext import commands
from discord.ext.commands import has_permissions

你需要为MissingPermissions定义你自己的错误

class MissingPermissions(Exception):

#and here's a "custom" check example
def has_perms(**perms):
    if has_permissions(perms):
        return True
    else:
        raise MissingPermissions
