How can I change the default debugger port number in node?

Question

I'm facing an error:

Starting inspector on 127.0.0.1:9229 failed: address already in use

How can I resolve this error?

You can do it with ``--debug`` or ``--inspect`` check my answer below. — Harshal Yeole, May 29 '18 at 05:36

You can do it this way:

node --debug=5412 app.js

You can also use --inspect option for node version >= v8

node --inspect=5622 app.js
