Build error from babel-plugin-module-resolver

[jesconstantine]

I've followed the installation instructions, and added the recommended expobook script to package.json but I'm seeing an error when I try to run expobook with yarn expobook and npm run expobook. See package.json, app.json, expobook.js and error output below. I'd appreciate any insight. Thanks!

export default expobook.build();

Hello, haven't run this in a while and looks like an issue with an update with expo. I'll give this a try today.

@kirkness thanks for your speedy response. FWIW when I pull your branch into my project I can successfully build expobook!
