[Ckan-users] Installing ckanext-harvest, having trouble with paster initdb call "DistributionNotFound"

[Adrià Mercader]

Hi Jenny,

I'm not familiar with the miniconda package manager but these errors seem
to suggest that the extension was not installed properly. I would suggest
using the pip binary that is part of the virtualenv, something like:


Step 31/46 : RUN /usr/lib/ckan/default/bin/pip install -e git+
https://github.com/ckan/ckanext-harvest.git#egg=ckanext-harvest
Step 32/46 : RUN /usr/lib/ckan/default/bin/pip install -r
/usr/lib/ckan/default/src/ckanext-harvest/pip-requirements.txt
Step 33/46 : RUN /usr/lib/ckan/default/bin/paster --plugin=ckanext-harvest
harvester initdb --config=/etc/ckan/default/production.ini

This is closer to what the install instructions suggest. Let me know if
this helps.
