Alignak doesn't start after `pip install`

[aftnix]

python -c 'from alignak.bin import VERSION; print(VERSION)'

A corrective version will be available soon. For the moment, add this file https://raw.githubusercontent.com/Alignak-monitoring/alignak/master/alignak/__init__.py in /home/aftnix/.local/lib/python2.7/site-packages/alignak/ folder

alignak-arbitar

now spits out usage. But still it gives a different exception before printing usage

alignak-arbiter -h
Error processing line 2 of /home/aftnix/.local/lib/python2.7/site-packages/alignak-0.1-py2.7-nspkg.pth:

Which OS are you using? I'll try to reproduce that

[aftnix]

$ uname -ar

Ok i have a workaround for you because the corrective is still not there.

Remove alignak (pip uninstall alignak) and install it again but with the --egg option (pip install alignak --egg)

Explanation : Actually this prevent pip to use the --single-version-externally-managed that seems to fail with namespace files. As pip says in the setup

   Skipping installation of /usr/local/lib/python2.7/dist-packages/alignak/__init__.py (namespace package)
    Skipping installation of /usr/local/lib/python2.7/dist-packages/alignak/modules/__init__.py (namespace package)

I use a workaround from people not having this parameter to get pip not use it

Namespace removed, see #238
