Error on running ckan -c /etc/ckan/default/ckan.ini run in composite (Not enough values to unpack)

Hi, I'm in the final stage to complete the installation of ckanext-composite but this error occur. I've already installed ckanext-scheming and ckanext-repeating. Any suggestion will much be appreciate.
