Answer 1

MissingPermissions is available only in the rewrite branch. If you don't have that, you need to uninstall discord.py then run

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

Then you can reorganize your imports. Either import commands and reference everything through that import, or import everything you use individually. Don't do both.

from discord.ext import commands

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

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

or

from discord.ext.commands import Bot, has_permissions

bot = Bot(command_prefix='!')

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

Answer 2

I'm assuming you're using Rapptz/Discord.py You cannot import commands from commands folder. No such thing.

I believe you you're looking for the core class's has_permissions method:

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

You will need to define your own error for MissingPermissions

class MissingPermissions(Exception):

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