Error redefining sync method

[pshangov]

Hi, I am attempting to get started with backbone-orm. When I run the following bit of code:

var Backbone = require("backbone");

var Project = Backbone.Model.extend({
    urlRoot : "xxx"
});

Project.prototype.sync = require("backbone-orm").sync(Project);

I get this error:

 ~\Development\backbone-fs> node .\bug.js

OS: Windows 7 64-bit node version 0.8.21 backbone-orm version 0.5.1

The same happens on latest version from git (eb085e5400f65a0d7b775b2de07f7e785ea2afab)

There is no error if I comment out the "Project.prototype.sync = ..." line.

Cheers, Peter

Thanks for letting us know mate (and soz for the delay in responding).

The error here is from us assuming Node 0.10+ streams are available - are you able to upgrade to Node 0.10+?

I've pushed a check that should allow it to work on older versions, but I'd recommend upgrading Node if possible.

Cheers again!

Works now, thanks!
