Then I analyzed many blogs to find the solution and it is very simple.

To resolve this issue we need a Developer Site.

So we need to create a new private site collection with Developer Site as template.

Got to the office 365 central admin and create a webapplication and name it  DeveloperAPP,



Select the Template as Developer site,



Then Go to the site Contents and Add an app then chose SharePoint Store,



Click add it button. Yes, Napa tool is added in your site.
