Failed to instantiate component or class "db".

[rakeshmishrait]

Hello Friends,

I am facing the issue on RBAC migration --> On terminal 'php init' set development mode. And create new mongodb database and user and after install this 'yii2-mongodb' set local-config in new mongodb connection.

When i run the command ' php yii migrate' give the error:- Yii Migration Tool (based on Yii v2.0.15.1) Exception 'yii\base\InvalidConfigException' with message 'Failed to instantiate component or class "db".' in /var/www/html/rbac/vendor/yiisoft/yii2/di/Instance.php:139

How to create using terminal 'auth_assignment, auth_item_child, auth_item, auth_rule' components through yii migrate.
