Error: TypeError when using with browserify about fresh-require

[DoomyTheFroomy]

Ok I have found my problem, I have fresh-require required within a mocha test case description, e.g.

describe('I will test it', function () {
  var fresh = require('fresh-require')
  assert(fresh) //will fail
})

but

var fresh = require('fresh-require')
describe('I will test it', function () {
  assert(fresh) //will work
})

Anyway i'll have to do some modifications to the browser.js

var map
if (sources[name]) {
  map  = sources[name][1]  
} else {
  map = {}
}
