Module '"@fullcalendar/core"' has no exported member 'CalendarOptions'

Hi,

I’ve just followed the installation guide for Angular: https://fullcalendar.io/docs/angular

I’m using Angular 8 with Universal in my project.

When I run ng serve I get a whole bunch of error messages that look Typescript related. Here are just some of them:

These are my package.json dependencies:
