Using drush on drupal 8? Dursh works very well with my Drupal 7, but when I try running Drush on Drupal-8 directory it throws some error message,

$drush pm-list

Command pm-list needs a higher bootstrap level to run - you will need invoke drush from a more functional Drupal environment to run[error]
this command.
The drush command 'pm-list' could not be executed.                                                                                 [error]
A Drupal installation directory could not be found     


could anyone tell me the solution for this problem?

any help is appreciated. Thank you.
Which version of drush? https://github.com/drush-ops/drush#drush-versions has a nice table, but in short you need the master branch from github if you want to work with Drupal 8.
