Trying to clear your Drupal site chache with drusch cc or drush cc all?
Drush should out put a list in response that looks like this:
promt$> drush cc Enter a number to choose which cache to clear. [0] : Cancel [1] : all [2] : drush [3] : theme-registry [4] : menu [5] : css-js [6] : block [7] : module-list [8] : theme-list [9] : registry [10] : less [11] : views
But instead, you may see something that looks like this:
promt$> drush cc Enter a number to choose which cache to clear. [0] : Cancel [1] : drush
Chances are you are not in the document root of the Drupal site on which you are trying to clear the cache.
