Error in installing

[zyadav]

I get an error when I try to install the files using composer:

composer require adesigns/nppes-api

The error is:

PS C:\xampp7\htdocs\hatchleafnppes> composer require adesigns/nppes-api
Using version ^1.0 for adesigns/nppes-api
Root package 'adesigns/nppes-api' cannot require itself in its composer.json

Please help.
