If you are behind a proxy, set it correctly in npm.

>npm config set proxy http://proxyhost:proxyport
>npm config set https-proxy http://proxyhost:proxyport

Notes:

1. For SSL/https proxies, the protocol in URL should be http not https

2. If your set up is on a Docker/Vagrant instance or a hosted VM, use IP address instead of hostname for proxy as the later might not be resolvable.

3. If there is no proxy , remove proxy config from npm

   >npm config set proxy null
   >npm config set https-proxy null
