Not sure how to debug this npm install error. This is a wordpress theme that comes with a built-in gulp/webpack task automation [closed]

not sure whats exactly keeping npm install from running successfully.

Nothing stopped it, npm ran successfully in your screenshot. The problem is that you saw the audit messages and thought it was an error/failure, which is not the case.

Fixing the audit messages is entirely optional at this point, and the issues auditing raises may not even apply to you. You should proceed to the next step, and report the audit messages to the authors.
