ES6 syntax for Using Transforms

[natac13]

I believe this to be a new issue after looking at the others.

I was working through the Using Transforms level and what I have setup is to write the code in ES6 then have babel transpile to ES5 and place in a dist/ folder. Here is my code.

'use strict';
import fs from 'fs';
import sprintf from 'sprintf';


let txt = fs.readFileSync('/home/natac/npm-global/lib/node_modules/browserify-adventure/problems/using_transforms/wake.txt', 'utf8');
let lines = txt.split('\n');
lines.forEach((line, index) => {
    if(index % 5 === 0) {
        console.log(sprintf('%3d %s', index, line));
    } else {
        console.log('   ' + line);
    }

});

When I run the ES5 version with node I get the desired output. However when using the provided command browserify -t brfs dist/transform.js | browserify-adventure verify I get an error that looks like....

I have tired moving the file to the root folder with no success.
