Installation instructions issue

[savage-ren]

I'm having issues with the installation instructions. I followed the instructions located at https://github.com/HHS/ckanext-datajson.

When I try to restart apache2 and hit the ckan server, I get the following error stack in the log file:

[Mon Sep 29 07:46:19 2014] [error] [client 127.0.0.1] mod_wsgi (pid=2683): Target WSGI script '/etc/ckan/default/apache.wsgi' cannot be loaded as Python module.

There is a blurb in the steps that imply that there may be a python dependency issue with wsgi and instructs the user to do the following:

“If you're running CKAN via WSGI, we found a strange Python dependency bug. It might only affect development environments. The fix was to revise wsgi.py and add:

import ckanext
before
from paste.deploy import loadapp”

I couldn't find this wsgi.py that had this "...paste.deploy..." line, but I did find the apache.wsgi file that was located in /etc/default/ckan/. I added the import line but I still get the same issue. Are there steps in the installation instructions that are missing. I'm not familiar with python but it does seem like this is a dependency issue. Would you be able to point me in the right direction.

It looks like your ckanext-datajson source code isn't installed inside your virtual environment. I believe it should be installed inside the src directory of your CKAN virtual environment. Also, I believe this has only been tested with CKAN 2.0.1, so you may have to modify the extension to work with more modern versions of CKAN

Zach,

It looks like your ckanext-datajson source code isn't installed inside your
virtual environment. I believe it should be installed inside the src directory
of your CKAN virtual environment.

*I'm not sure what you mean by this. When you say CKAN virtual
environment, do you mean the step where I have to run the activate script
to be in the python environment? Do I have to be inside a certain folder
(src?) to run *

pip install -e git+
https://github.com/HHS/ckanext-datajson.git#egg=ckanext-datajson

I believe this has only been tested with CKAN 2.0.1, so you may have to
modify the extension to work with more modern versions of CKAN

How do you modify the extension to work with modern versions of CKAN?

Thank you so much for all your help!
