Newman install Error Etimedout


This is the error I get when I try to install Newman through NPM.

ETIMEDOUT ETIMEDOUT request to failed, reason: connect ETIMEDOUT This is a problem related to network connectivity. In most cases you are behind a proxy or have bad network settings.

If you are behind a proxy, please make sure that the ‘proxy’ config is set properly. See: ‘npm help config’

Github is blocked in my corporate environment. So I downloaded Newman zip and copied locally in my system. And tried to install with npm install -g newman-develop/ command. But still getting the same timed out error for and eventemitter3.
Installation is not proceeded after that. Can someone help me install newman in my system pls?
