OSX does not work

[cromestant]

I have a simple sample code taken from the documentation:
test.js

var avsc = require('avsc');
    var type = avsc.parse('./schemas/pet.avsc')
    var pet = {kind: 'CAT', name: 'my cat'}
    var buf = type.toBuffer(pet); // Serialized object.
    var obj = type.fromBuffer(buf); // {kind: 'CAT', name: 'Albert'}

    console.log(buf)
    console.dir(obj)

And a simple avsc file in schemas/peg.avsc

{
  "name": "Pet",
  "type": "record",
  "fields": [
    {"name": "kind", "type": {"name": "Kind", "type": "enum", "symbols": ["CAT", "DOG"]}},
    {"name": "name", "type": "string"}
  ]
}

on ubuntu, running node test.js I get:

cromestant@tweb-lab-web-01:~/test$ node test.js 
< Buffer 00 0c 6d 79 20 63 61 74>
{ kind: 'CAT', name: 'my cat' }

however con El Capitán:

Charles-Romestant-MacBook-Air:activity cromestant$ node test.js 
/Users/cromestant/Codigos/node/activity/test.js:4
var buf = type.toBuffer(pet); // Serialized object.
               ^

Thanks for the detailed info. From the package.json it seems your OS X install is using an old version of avsc (1.0.2). Upgrading to the current version (3.1.1) should fix this. Let me know if not.

[cromestant]

you were absolutely right.
weird thing is that I have no idea why I specified the version that old...
thanks and sorry.
