Bitnami Drush Errors?

If you using Bitnami’s Drupal 7.9.1 stack and getting the following error:

“Command pm-update needs a higher bootstrap level to run – you will need invoke drush from a more functional Drupal environment to run this command.”

Changing localhost to 127.0.0.1 in the settings.php file may help to cure your issue.
