but if i go to the build subdir, and execute (in the pyzmq subdir) python setup.py install then the package is installed correctly and its working ....

That looks like something is wrong in the pkg_resources data, and may not have to do with pyzmq.

Can you do:

python -c 'import pkg_resources'

?

works:
(venv)cereal@igor:/domogik-mq$ python -c 'import pkg_resources'
(venv)cereal@igor:/domogik-mq$ python
Python 2.7.8 (default, Oct 18 2014, 12:50:18)

import pkg_resources
pkg_resources
<module 'pkg_resources' from '/venv/local/lib/python2.7/site-packages/pkg_resources/init.pyc'>

What about pip list? Does it work if you leave out the deprecated --no-clean arg?

[minrk]

Can you provide more information about the system? What distro, are you using the system Python, etc.? How exactly did you create the virtualenv? Do you see the same error if you create a brand new virtualenv with no packages in it (and no --system-site-packages)?

[Cereal2nd]

we can close the issue, it was a problem with the installed version of python-daemon, when we switched to another version of this package it got solved

Thanks for checking.
