I just setup a new Drupal environment with Mamp. I can access my website just fine, but whenever I want to run drush cr I get the following error :

exception 'RuntimeException' with message 'Missing $settings['hash_salt'] in settings.php.' in /Applications/MAMP/htdocs/soa-drupal/core/lib/Drupal/Core/Site/Settings.php:130                     [error]

I'm using PHP 5.5.18, Drupal 8, and drush 7.0-dev.

This is my drush status

My settings.php file does have this hash_salt line.

$settings['hash_salt'] = 'bUmc1PV9VzwAXban_VVRtSKKwOBp7QNugOCWzsUrRgyy7Zl7D2dJm-J8Wb5FWOUrDKH7zepC2A';

I have tried changing localhost to, updating drush, adding pretty much everything to the $PATH.. No luck so far, and I've visited every single website mentioning this error.

    This should not have been closed. This may help someone "Can you look at your settings.php file and see if you have $settings['hash_salt'] set to anything? Thats required in D8." => github.com/drush-ops/drush/issues/1050#issuecomment-67723261 – Elijah Lynn Apr 20 '16 at 2:04
  • @ElijahLynn: "My settings.php file does have this hash_salt line." The OP already said the settings.php file has that variable set. – kiamlaluno May 15 '16 at 11:32
  • What if the there is a settings.local.php file resetting the hash salt line? – Jigarius Jan 26 '17 at 20:44
  • If your settings.local.php needs adding just use this and it will work for you after a cache reload $settings['hash_salt'] = 'CHANGE_THIS'; – Biged Jun 27 '18 at 14:05
