I'm having the same issue. The alias fix is working fine, but only for TweenLite. I have the following config.
alias: {
TweenLite: 'gsap/src/uncompressed/TweenLite',
TweenMax: 'gsap/src/uncompressed/TweenMax',
Easing: 'gsap/src/uncompressed/easing/EasePack',
ScrollToPlugin: 'gsap/src/uncompressed/plugins/ScrollToPlugin'
}
Everything works, except TweenMax.
Uncaught TypeError: _TweenMax2.default.to is not a function
_TweenMax2.default is simply an empty object.
Any clues?
