Answer 1

I think you might be sitting behind a proxy. You will have to set-up npm and node behind the corporate proxy

Open an command prompt or terminal session and run the following commands to configure npm to work with your web proxy. The commands use proxy.company.com as the address and 8080 as the port.

npm config set proxy http://proxy.company.com:8080
npm config set https-proxy http://proxy.company.com:8080

Please refer and follow the steps -
