please, provide your package.json, maybe you missing something because we have some problem with rxjs upgrade

[cagline]

I fixed this issue by installing rxjs-compat
npm install --save rxjs-compat

update.angular.io
According to this rxjs-compat can be removed after all of your dependencies have updated to RxJS 6.

any way here is my package.json

yes, that exactly what I'm going to talk with you @cagline . but I want to make sure that you missing rxjs-compat. should we left this repository open then make an update in angularfire2 to includes rxjs-compat or close it and we update directly our library to rxjs 6 without includes rxjs-compat? @davideast

[cagline]

update.angular.io
According to this rxjs-compat can be removed after all of your dependencies have updated to RxJS 6.
for now i think you can make an update inangularfire2to includes rxjs-compat

[hiepxanh]

yeah, that right 😄 maybe @jamesdaniels can make an small update for this issue

[SebastianPodgajny]

rxjs-compat is not meant to be used in libraries...

[jamesdaniels]

Fixed in angularfire2@next

[FouomaOscar]

That is my code example fine https://github.com/FouomaOscar/firebase-authentication-with-angular-6. It's works fine

[matthewharwood]

Yeah I had to install angularfire2@next to remove these errors
