Error using Drush with new Drupal installation of Drupal 8

I created a new server with Drupal 8 preinstalled. It already had Drush installed but whenever I run drush with a command in the working drupal directory I get the following error:

Command needs a higher bootstrap level to run-- you will need ot invoke drush from a more functional Drupal enviroment ot run this command.

I haven’t been able to get drush to work at all with this Drupal 8 install. I have used Drush regularly on Drupal 7 install with no problems.

Full message below: Command pm-update needs a higher bootstrap level to run - you will [error] need to invoke drush from a more functional Drupal environment to run this command. The drush command ‘pm-update’ could not be executed. [error] Drush was not able to start (bootstrap) the Drupal database. [error] Hint: This may occur when Drush is trying to:

• bootstrap a site that has not been installed or does not have a configured database. In this case you can select another site with a working database setup by specifying the URI to use with the --uri parameter on the command line. See drush topic docs-aliases for details.
• connect the database through a socket. The socket file may be wrong or the php-cli may have no access to it in a jailed shell. See http://drupal.org/node/1428638 for details.
