[ckan-dev] Antwort: Re: setuptools versions

Fri Jul 22 07:07:21 UTC 2016

Shane,

the reason for the "KeyError: 'ckanext'" error usually is indeed a problem
with how pip treats Python namespace packages. In particular, you cannot
mix "normal" installations and editable ones ("pip install -e ..." or
"python setup.py develop"). See https://github.com/pypa/pip/issues/3.

To solve that issue, we install all CKAN extensions in editable mode (i.e.
"pip install -e ..."). That seems to work fine. If you're already running
into the error then you'll probably have to recreate the virtualenv from
scratch.

Regards,
Florian
