I have created a drupal project using composer:

composer create-project drupal-composer/drupal-project:8.x-dev ./ --stability dev -vv

Then I downloaded drush using this command:

composer global require drush/drush

Now I try to install the drupal site using this drush command:

drush si standard --db-url=mysql://***:***@localhost/recommande_db --site-name=***** --account-name=*** --account-pass=*** --account-mail=*****

I'm getting this error:

exception 'Drush\Sql\SqlException' with message 'Unable to find a matching SQL Class. Drush cannot find your[error]

database connection details.' in
