Problem with yii2 and Netbeans

Hi all, im trying to setting up the ide to work with yii2.

Id like to use Netbeans or PHPStorm.

With the first i can create a yii2 base project and run it in the browser but i still keep the errors (see the attachments).

If anyone have a link or want to write the correct instruction for setting up Netbeans or PHPStorm with yii2 are very wellcome.

Any help is very appreciated.

you may exclude

vendor

dir from project.

I just ignore the errors in vendor!
