Thanks for the post! I would like to use .env variables in my cli app but when I npm link it, it cannot reach my .env files from any other directories. Do you have any advice solving this problem?

Have you tried setting the exact path of your .env file in the .env config as so:

require('dotenv').config({ path: '/absolute/path/to/your/.env/file' })
