SSL Error: CERT_UNTRUSTED while using npm command

Question

I am trying to install express framework using npm command but getting following error.

error message is

E:\\myFindings\\nodejs_programs\\node>         


        

Answer 1

I think I got the reason for the above error. It is the corporate proxy(virtual private network) provided in order to work in the client network. Without that connection I frequently faced the same problem be it maven build or npm install.
