找不到模块“newman”需要堆栈：

Question

I installed "newman" package on my computer globally and able to run newman on the command 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?

Answer 1

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.
