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

npm ERR! node -v v0.8.0
npm ERR! npm -v 1.1.32

Update your node.js installation.The following commands should do it (from here):

sudo npm cache clean -f
sudo npm install -g n
sudo n stable

Edit: okay, if you really have a good reason to run an ancient version of the software, npm set ca null will fix the issue. It happened, because built-in npm certificate has expired over the years.
