Error pkg_resources.DistributionNotFound: ReviewBoard after install

[mot...@free.fr]

I've followed the installation procedure on mu Ubuntu box 14.04, using Apache as HTTP server and PostgreSQL.

I've successfully created the site, and enabled the site on my Apache.

When I'm connecting to the application, I have the following message displayed: "Review Board is taking a nap ..."

In the Apache log file:

But obviously the ReviewBoard package is correctly installed:

$ sudo easy_install ReviewBoard
Searching for ReviewBoard
Best match: ReviewBoard 2.0.6
Processing ReviewBoard-2.0.6-py2.7.egg
ReviewBoard 2.0.6 is already the active version in easy-install.pth
Installing rb-site script to /usr/local/bin
Installing rbssh script to /usr/local/bin

Using /usr/local/lib/python2.7/dist-packages/ReviewBoard-2.0.6-py2.7.egg

I'm not used to Python web site, what do I have missed?

Thanks,

I finally found out that I have installed the wrong apache package, namely libapache2-mod-wsgi-py3 rather than libapache2-mod-wsgi.

ReviewBorad has obviously been installed by easy_install in Python 2.7 shared directories rather than in Python 3. I'm clearly not a Python specialist, installing libapache2-mod-wsgi (which automatically remove libapache2-mod-wsgi-py3) solved the problem ;-)
