title: Yii2 Error: Class dektrium\rbac\Module does not exist
body: <p>I have just updated my composer and after that when i run my Yii2 application i got this error "Class dektrium\rbac\Module does not exist" i am using rbac in my application.</p>
  
  <p>I checked desctrium\rabc directory there is no file with Module class. However i can see two new files RbacWebModule, RbacConsoleModule in that directoy.</p>
  
  <p>I have a backup of my application on other server. so do i have to put my backup there to correct this error or is there any other solution. i can see in my vendor folder all other folders also get updated with composer update. So how to get rid of this error.</p>
  
  <p>Thanks in advance.</p>
