error in Gii on Update of Yii

Today I have updated my Yii2 installation running the command

composer global require "fxp/composer-asset-plugin:1.0.0-beta3

composer update --prefer-dist

Now when I am trying to access Gii, I am getting the error:

The file or directory to be published does not exist: 


Why I am getting this error, anyone else getting this error?

Any solution?
