I've tried adding Tweenmax and other JavaScript libraries to my Ruby/Spree app.
But I've not been able to make it work.
I've added separate files to assets/javascripts/store
add included them in the all.js file
Yet it seems that the app doesn't run Tweenmax.
Can someone explain to me how to add Tweenmax to Ruby on Rails & Spree?
Did you try greensock-rails gem?
