[DiegoDVillacreses]

After installing DataPusher-Plus for development following the instructions on: https://github.com/dathere/datapusher-plus#datapusher-database-setup . After successful installation of pip install datapusher-plus within the suggested environment: . /usr/lib/ckan/dpplus_venv/bin/activate.

I get the following error after trying to start DataPusher with /usr/lib/ckan/dpplus_venv/bin/uwsgi --enable-threads -i /etc/ckan/datapusher-plus/uwsgi.ini:

Under dpplus_venv when trying to import datapusher:

CKAN server on the other hand is running fine. Only DataPusher seems to fail.
