[DanSnow]

This package depend on Promise and Object.assign, please ensuring that you have loaded any ECMAScript 2015 polyfill for IE.

If you still get the same error, please provide a code snippet containing a set of reproducible steps.

I'm using this package for some polyfill stuff:
https://github.com/stefanpenner/es6-promise

Do I need another package for something else?

[DanSnow]

You will need https://github.com/es-shims/es6-shim for Object.assign.
Or any polyfill that includes Object.assign.
