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

[Jenny Brown]

Install instructions show:

(pyenv) $ paster --plugin=ckanext-harvest harvester initdb
--config=/etc/ckan/default/production.ini

but I am receiving an error.  I'm on CKAN 2.6.  I'm installing in docker on
ubuntu, using the python-ckan-2.6-trust-amd64 deb.
My ckan installation was working fine until I tried to add the harvester
extension, so I think my issues are specific to that.


I noticed first that the pip install step landed the extension in
"/src/ckanext-harvest" off the root instead of inside the ckan dir.  I
moved it into place, but I am not sure if there are additional config steps
to do there or if something was wrong during my pip install that it landed
in an odd place.


Secondly, the paster command files with an error that seems like it either
doesn't know about plugin ckanext-harvest, or that some other component was
missing, but the error is unclear to me.


Here's the relevant output from the docker build where it's running.

Step 30/46 : RUN . /usr/lib/ckan/default/bin/activate
Step 31/46 : RUN /opt/miniconda/bin/pip install -e git+
https://github.com/ckan/ckanext-harvest.git#egg=ckanext-harvest
Step 32/46 : RUN mv /src/ckanext-harvest /usr/lib/ckan/default/src
Step 33/46 : RUN cd /usr/lib/ckan/default/src/ckanext-harvest &&
/opt/miniconda/bin/pip install -r pip-requirements.txt
Step 34/46 : RUN /usr/lib/ckan/default/bin/paster --plugin=ckanext-harvest
harvester initdb --config=/etc/ckan/default/production.ini

The command '/bin/sh -c /usr/lib/ckan/default/bin/paster

--config=/etc/ckan/default/production.ini' returned a non-zero code: 1


Thanks!
