Can't build firebase@4.0.0 and angularfire2@2.0.0-beta.7-pre together. ERROR: Calling function 'OpaqueToken', function calls are not supported

I'm working on a Angular CLI project and trying to build using 'ng serve'

Version info

**Angular:**4.1.3

**Firebase:**4.0.0

**AngularFire:**2.0.0-beta.7-pre

Debug output

** Errors in the JavaScript console **
ERROR in Error encountered resolving symbol values statically. Calling function 'OpaqueToken', function calls are not supported. Consider replacing the function or lambda with a reference to an exported function, resolving symbol FirebaseUserConfig in project-directory/node_modules/angularfire2/tokens.d.ts, resolving symbol AngularFireModule.initializeApp in project-directory/node_modules/angularfire2/angularfire2.d.ts, resolving symbol AppModule in project-directory/src/app/app.module.ts

Upgrade to rc0 as beta.7 is not 4.0 compatible. Also wait until #999 is merged until upgrading to Firebase 4.0.

Thanks. That solved my problem.
