I have Node 16.13.1 installed and I installed openai globally with 'npm install -g openai'. I imported the packages inside my script using:

const { Configuration, OpenAIApi } = require('openai')

However, when I ran my script, I got this error:

PS D:\Projects\OpenAI-Chat> node conversation.js
node:internal/modules/cjs/loader:936
  throw err;
  ^

Error: Cannot find module 'openai'

}

How do I fix this?
