No Drupal Site Found when clearing cache I installed drush using composer following the instructions here: http://docs.drush.org/en/master/install/

When trying to run drush cc all I get this error:


  No Drupal site found, only 'drush' cache was cleared.[warning] 'all'
  cache was cleared. [success]


I added this line:

export PATH="/Applications/MAMP/bin/php/php5.6.2/bin:$PATH"


to my .bash_profile and restarted bash and MAMP. Still no luck. Any ideas? 

This is my drush status:

I'm running it from Drupal project folder.
I figured out that you will need a mysql server installed and included in path, even if you are using mysql from AWS RDS.
