[Twisted-Python] TypeError: Class advice impossible in Python3.

[ABHISHEK BHAT]

Hi
I am trying to use Twisted and PB but running into the below error in the zope.interface module.

I am running Python 3.3 and zope.interface version 4.0.3. I am running this on a RedHat system.

Does anybody know how to get around this problem?





bash-3.2$ python pb_client.py


Traceback (most recent call last):

  File
"pb_client.py", line 2, in <module>

    from
twisted.spread import pb


  File

    from
twisted.cred.credentials import IAnonymous, ICredentials

TypeError: Class advice impossible in Python3.  Use the @implementer class decorator instead.
