Error: app.auth is not a function

I got this error when I upgrade to Firebase 5.5.1
But same code works when I downgrade to Firebase 5.4.2 (no error)

ERROR Error: Uncaught (in promise): TypeError: app.auth is not a function
TypeError: app.auth is not a function
at auth.js:12

Firebase 5.5.1
@angular/fire 5.0.0
