Node JS Cannot find module 'node-properties-parser' Error while running as normal user in Amazon Linux

Question

I have installed node-properties-parser globally by running npm install -g node-properties-parser as normal user(vaisakh). Then i ran my test.js file with the command node test.js now it's throwing the error

Error: Cannot find module 'node-properties-parser'

I ran the above npm install -g node-properties-parser as root user and run the node test.js here it's working fine. But why it's throwing the error while running as normal user?

Thanks. Finally i found the answer, it's working when in run sudo npm install node-properties-parser without the -g option. But still i don't know why the -g option is not woking, in the docs it's given as install globally.
