Node npm ENOSELF error - installing a package in its package in branch RxJS package

I was facing issue while installing node packages,

Please review error  screenshot as well,

SOLUTION  : just rename package.json file with package1.json and start executing your package command.

To fix that, open your package.json file and change/rename the name of the project.

Error was faced during package installation  as below :
$ npm install rxjs webpack webpack-dev-server typescript ts-loader


try out with this:
$ npm install webpack webpack-dev-server typescript ts-loader

if you face same issue, just rename package.json file as per my comment and execute your package it will create automatically new package file.
