Typings installation error

Thank u for your responseBhuvanesh Mohankumar.

Yes it returns the json response and i also tried that one into my personal pc it works fine. i think the proxy settings not allowed to download the typings package .do u have any idea?

Have you tried the URL in any Browser & Check is that return JSON response?

If you find error or invalid value then check your firewall settings and try it after disabling teh blocks in firewall.
