Native Module cannot be null when using react-native-purchases

Trying to run an expo react native project w/ revenue cat integration. Whenever I had the react-native-pruchases library downloaded though, I continue to get this error.

Invariant Violation: Native module cannot be null

I downloaded the library by running npm install react-native-purchases --save, I didn't do any of the additional iOS setup the docs outlined. I've been going crazy over this so some help is appreciated.
