console.debug not in NodeJS

[pjobson]

node v6.8.1 supports:

Console {
  log: [Function: bound ],
  info: [Function: bound ],
  warn: [Function: bound ],
  error: [Function: bound ],
  dir: [Function: bound ],
  time: [Function: bound ],
  timeEnd: [Function: bound ],
  trace: [Function: bound trace],
  assert: [Function: bound ],
  Console: [Function: Console] }

Tesseract fails on line 123 when it attempts to call the debug method.

var Tesseract = require('tesseract.js');
var myImage = './screenshot_05.png';
Tesseract.detect(myImage)
    .progress(function(message){
        console.log('progress is: ', message)
    });

 ~/code/tesseract_test $ node index.js
