I have tried and get the same error :
Here's my ./styles/config.rb
error styles/app.scss (Line 2 of styles/../sdk/resources/themes/stylesheets/sencha-touch/default/core/../_mixins.scss: File to import not found or unreadable: recipes/background.
My SDK is in ./sdk
# Delineates location of the config.rb file which should be in the same directory as your SCSS file(s)
sass_path = File.dirname(__FILE__)
# Points to the location of the CSS file(s) you'll call from your HTML document
css_path = File.join(sass_path, '..')
# Points to the images directory used by the Sencha Touch theme
images_dir = File.join(sass_path, '..', 'sdk', 'resources', 'themes', 'images', 'default')
# Points to the Sencha Touch theme
load File.join(sass_path, '..', 'sdk', 'resources', 'themes')
# Denotes how the CSS files are compiled by Compass
output_style = :compressed
environment = :production
I am running I really do not see what's wrong with it.
