Answer

Reason of this error is :

1. Try to install this widget using Composer.It will place all folder at there positions.
   
   2.If doing it manually then try to place the files as on there place otherwise it will not work it happened with me also.

Recommend way is use composer other wise use Install Yii2 extension manually without using Composer
