Yii - how to fix error in ext.Eauth?

Question

Yii

I downloaded an extension for authorization through social networks on Yii from Git.
I did everything according to the instructions.
When the widget is rendered

<?php $this->widget('ext.eauth.EAuthWidget', array('action' => 'reg/index')); ?>

In response, I see:
The alias "ext.lightopenid.loid" is incorrect. Make sure it points to an existing PHP file.
Who faced such problem? Who will advise what (sane and in fact)?

Answer 1

Looks like the lightopenid extension is not installed.

Answer 2

Loid extension installed?
