Error while installing typings

I am windows10 user and tried to install angular2. I couldn’t insatll it with npm install at first but with an modified package.json Ii was able to install it.

"version": "1.0.0",
"scripts": {
"start": "npm run lite",
"lite": "lite-server"
},

It didn’t created a typings folder so I ran npm run typings -- install which produced this error

F:\AngularJS\my-proj>npm run typings -- install

I found the problem… It was the proxy. I created a .typingsrc file with

{
  "rejectUnauthorized": false
}

It installed typings successfully.

$ npm run typings install

> angular2-quickstart@1.0.0 typings F:\AngularJS\my-proj
> typings "install"

Are you behind a proxy?
