Error: Class 'Drupal' not found in bootstrap.inc

Question

Please tell me what I'm doing wrong. I'm unable to run drush, see error below:

[~/public_html/d8]# drush -d status

I'm using:

• Drush Version : 6.0-rc4
• drupal 8.0.0-beta7
• PHP 5.4.38
• MySQL 5.5.42-37.1

Answer 1

Drush 6.x only works with Drupal 6 or 7, upgrade to Drush 7.x.
