[ckan-dev] Installing datagovuk / ckanext-os

[Hildegard Gerlach]

Hello,

I installed datagovuk / ckanext-os
https://github.com/datagovuk/ckanext-os

because we would like to use our own map for spatial search.
When I try to enable the

ckan.plugins = os_search os_preview

ckan doesn't start any more.

Error message in the logfile:
ImportError: No module named celery

I have the default CKAN installation (not datagovuk) with spatial 
extension enabled on Redhat 6.

Thanks

Hilde
