Random Uncaught Error: Cannot find module 'crypto'

I’ve got this error when calling Random.id(). i have installed Random as meteor package and i got this error. I have then istalled it as npm with same error. And I got the same Error with the npm package meteor-random. I’m using Meteor, Mantra and Redux.

can some one please help me.

Solved! Random works!

I did an import of meteor-random in the server part and that did not exists.
