[ckan-dev] ImportError: cannot import name get_library_registry

[David Lemayian]

Hi Reinoud,

Just on your question on an easy way to install python packages required,
this should help:

pip install -r /usr/lib/ckan/default/src/ckan/requirements.txt

Also on the Error on SQLAlchemy, it seems you need to downgrade it
(SQLAlchemy) to get it working.

Cheers,
David.
