Cannot export theme settings to the .info file I am using Drupal 7. After modifying a setting for my theme in the Appearance menu, I get the following alert message on my site's homepage:

The settings for this theme are currently served from a variable. You might want to export them to your .info file. This is optional and can be done the Drush command 'drush omega-export'.


However, when I try to run the drush omega-export command, it fails:

$ drush omega-export
The drush command 'omega-export' could not be found.  Run `drush           [error]
cache-clear drush` to clear the commandfile cache if you have installed
new extensions.
A Drupal installation directory could not be found                         [error]


This happens even if I run as root. I ran the drush cache-clear drush command successfully, but that unfortunately did not fix the issue. How do I fix this?
The "omega" theme is the base theme for my theme. It needed to be Enabled, but not set as the default. After enabling the theme, the drush omega-export command worked successfully.
