I have this error:

    

> Fatal error: Class 'Locale' not found in
> vendor/magento/framework/Locale/Bundle/DataBundle.php
> on line 64

in Magento 2 when I try do use this command to clear the cached files:

    php bin/magento setup:static-content:deploy
Does anyone else have this problem?

Later Edit:
I want to regenerate the static content, it was a bad wording before.
I am using Magento 2.0.2 and I used the downloaded file from magento.com
