How to debug npm install execution

Question

What´s the recommended way of debugging an npm install operation?

I have an exception being throw (similar to https://github.com/hyperform/hyperform/issues/63 or https://github.com/npm/npm/issues/17858) and would like to know how to debug the source code of it.

From NPM's wiki:
"If you are having trouble with npm install, use the --verbose option to have more details."

(Not to be confused with npm_debug=1 flag, which is only valid for debugging the process of installing NPM itself).
