"ImportError: cannot import name types" when doing import oslo_config.cfg

[Ritesh]

I am using a very simple publisher code (which is being called from pecan rest api to put a message onto rabbitmq)

The Code looks like this

import oslo_config.cfg # -->> This line gives the error
import oslo_messaging as messaging

class AttisProducer:
    log = logging.getLogger()
    def getTransport(self):
        configutil= ConfigurationUtil()
        transport_url = 'rabbit://attis:attis@192.168.56.105:5672/'
        transport = messaging.get_transport(cfg.CONF, transport_url)
        return transport

I get following error .

This is how my virtual env looks like (i am assuming this is due to some library incompatiblility )

ok after some googling found that due to some reason even through the oslo_config was being picked up from virtal env when it internally called oslo.config it went to my systems path
I followed fllowing solution(just changed to oslo config 1.6) and it worked !

Dont think this is a bug , you can close it !

[Longjie_Cao (grasson1101)]

From you previous comment, there are no oslo_config directory under you virtual dev. If you call the oslo_config, it will go to your system path. I think you should install oslo_config to your virtual env, like using:
pip install oslo.config
