CKAN extensions not working if ckanext-sparql activated

Question

I'm trying to install several extensions on CKAN. They all seem to work perfectly fine until I install ckanext-sparql.

I've followed the instructions on its website, and if I have the SPARQL extension working alone, it works great, but when I try to add another extension, it gives me back the following error message:

ckan.plugins.core.PluginNotFoundException: sparql_interface

I have installed the extensions on the virtual environment and they all work except when I try to add SPARQL. The SPARQL extension works, but only if no other extension is activated.

Answer 1

I've just solved the problem. It turns out that the ckanext-sparql extension wasn't registering itself correctly. I've added it manually to the easy-install.pth file where all the other extensons were, and now everything works fine.
