How to create CKAN example_theme - it is not working

I am following the tutorial at http://docs.ckan.org/en/ckan-2.6.2/theming/templates.html

I, of course, installed this version 2.6.2 and have successfully completed the default setup.

step6) When I run the command to serve: paster serve --reload /etc/ckan/default/development.ini

I get the following error:

ImportError: No module named plugin

I see a lot of people getting the same error, there must be a reason for that. see the link: https://github.com/ckan/ckan/issues/3146, ckan 2.3 problems with adding the example_template plugin

Does anyone have a solution for this?

Thanks in advance

The problem is that there is that the main ckan repository also has an ckanext/example_theme (which is uses in its tests) and it's finding that one. That one doesn't have a plugin.py in the usual place, hence the error.

The solution is to use a different name than "example_theme".

There are two solutions:

  1. To convert an existing extension, you need to rename its "example_theme" directory, edit the path to it in setup.py's entry_points, and then run python setup.py develop again.

  2. Upgrade to CKAN 2.7.X (or later) and recreate the extension again. If you have any .pyc files in your extension directories, delete them. Restart CKAN.
