npm init
# <init a package>
npm i lodash --save
touch lodash.js

In lodash.js

module.exports = {
  'VERSION': 'should be me'
};

Now in the REPL

console.log(require('./lodash').VERSION);
// => 4.6.1 instead of 'should be me'

Put the same code in a file

In foo.js

console.log(require('./lodash').VERSION);

Then

node foo
# logs 'should be me'

It would work in the REPL if I changed the path from './lodash' to './lodash.js'.
