Plugin not found error when running paster commands

[abedkhooli]

Installed dcat on ckan 2.8.3 and it worked (after chmod 777 -R /usr/lib/ckan/default/src/ckan/ckan/public/base/i18n), but when I run paster commands like plugin-info or jobs list I get an error saying plugin not found: dcat. I did not include the harvester. My plugins include dcat dcat_json_interface and when I remove them from ini pater commands work.
Here's the dcat location.
