Trying to implement authentication with firebase (And fails)

[y~c]

Hey,

I'm connected to firebase's real time database.

Now I am also trying to authenticate users.

What happens is that at some point I get such an error:

node_modules/@angular/fire/auth/auth.d.ts: 8:22 - error NG6002

I think there is some kind of conflict because I installed @angular/fire and then angularFire2.

I worked with a guide to connecting to firebase's real time database.

And then I worked with an authentication guide that worked with angularFire2..

Apparently this is what caused the problem.

Bottom line I have some questions:

1. What is the difference between @angular/fire to angularFire2?

2. Is it possible to work on the same project with both of you at the same time?

3. If not, what shuld I do ..?

Thanks in advance!

p.s. Sorry for my English... working on it too.. ;)
