"ImportError: No module named pika" when starting the gather_consumer

[opensas]

I followed the guide at https://github.com/ckan/ckanext-harvest/blob/master/README.rst

I had to install the plugin and the requirement with sudo because of permission to write to /usr/lib/ckan/default/src/ckan/src/ckanext-harvest

When I start the gather_consumer, I get the following error:

(default)ckan@ckan1:/usr/lib/ckan/default/src/ckanext-harvest$ paster --plugin=ckanext-harvest harvester gather_consumer --config=/etc/ckan/default/production.ini

I could solve it login in as root with sudo su

$ sudo su

I guess I must be doing something wrong when installing the dependencies with sudo. If anubody can point in the right direction I can help updating the install documentation.

Sorry, after installing requirements as root everything seems to work fine... I can run all the commands as a regular user. Perhaps we could update the docs to state this...

You shouldn't need sudo to do pip installs. Are you running ckan from source or package? Did you run this line from the docs:

sudo chown `whoami` /usr/lib/ckan/default

http://docs.ckan.org/en/latest/maintaining/installing/install-from-source.html

I installed from package, so I missed the chown, I guess that explains it
all, I'll give it a try and then I'll tell you

@opensas did this solve your issue? I'd like to close the issue if possible.
