Check if you have 2 React instances running

I’ve got React installed from atmosphere, and react-mixin from npm. It seems that react-mixin depends on react, so do I have 2 reacts running in my app? How can I check this - I don’t see ‘react’ in my node_modules folder, however there is a react folder in node_modules when I open the sources tab…

Are you using Meteor 1.3? If so don’t install React from Atmosphere. Remove it and install it from npm. Check out the draft 1.3 React section of the Guide for more info.

Yes I am using 1.3.
It seems I have to drop the package, because it uses kadira:react-layout that depends on react… ;/
