I'm getting this error independent on a number of different configs. (For example, received it on lodash and chef).

master VS develop branch schema? I would merge develop to master btw \o/

[pixelastic]

I'll move everything on master and remove the develop branch to avoid confusion.

@dustincoates Could you try again? On master for real this time (I just updated it) :)

[dustincoates]

@pixelastic @redox I think that was the problem. I'm going to try again later today. :)
