I installed "newman" package on my puter globally and able to run newman on the mand line

npm install -g newman 

However, I need to run my test collections in nodejs script and the following statement throws an exception

Cannot find module 'newman' Require stack:

const newman = require('newman'); 

Any ideas to fix this problem?

• Could you post the full error? – Ömürcan Cengiz Commented Nov 1, 2019 at 20:53
• Just updated the question with full error stack – AustinTX Commented Nov 1, 2019 at 21:12
• 2 You would need to create a package.json file and save Newman as one of the dependencies before running the script – Danny Dainton Commented Nov 1, 2019 at 21:26
• This works, I was confused about the global package. I need to install it locally too. – AustinTX Commented Nov 3, 2019 at 14:41

you have installed newman package globally. In order to use it in your project you need to install it locally in your project. If your project does not have a package.json file you can init it by running npm init in the root directory of your project. After that you can install the package by npm install newman to add it to your dependencies. Now the package can be required within your project.
