@yazan-alomari Update to the 5.0 branch to fix this error. This also upgrades you to the new database API. The migration is easy and the guide is here. However, if you need to stay on the old version use the angularfire2/database-deprecated module.

Still getting the "no exported member 'Promise'" error.

[davideast]

@EstiShay What version of Firebase, Angular, and AngularFire are you on? And can you print the exact error?

firebase.Promise was removed in Firebase 4.5.0. AngularFire 5.0 accounts for this change. You're likely still on the old AngularFire package.

[EstiShay]

angularfire: 5.0.0-rc.0-next
firebase: 4.2.0-4.5.0
angular: 4.2.4

We're still getting it. Tried to roll back to pre-Firebase 4.5.0 and use AngularFire 4.0.0-rc.0. This way we get a screen full of Promise errors. When we update to 5.0, we still get one Promise error.

ERROR in /Users/Guest/Desktop/.../node_modules/angularfire2/firebase.app.module.d.ts (12,28): Namespace 'firebase' has no exported member 'Promise'.

Is there a documentation for updating the previous code in accordance with AngularFire 5.0?
I have tried the changes mentioned here.Still I'm unable to resolve the issue.

@davideast I think you should be waited for a little before closing the ticket!
Why I have to do full refactor for just a little modification?

This is fixed in master

Hi,
i have the same problem here, and i don't want to make changes on my code, because in this case i should make a lot of changes
how can i downgrade firebase and angularfire to resolve this issue ?

[CharlesSuttie]

Hi,

I had a look at the commit that @Maistho mentions above. But when I look at that file in my local node_modules, the changes are not there. So, I checked the version of angularfire2 in my local node_modules: it's 5.0.0-rc.0-next.

In my project, my package.json specifies "angularfire2": "^5.0.0-rc.3"

When I run yarn add angularfire2 5.0.0-rc3 I get error Couldn't find package "5.0.0-rc.3" on the "npm" registry.

When I delete node_modules and run npm install I can see "version": "5.0.0-rc.3" in my local node_modules. And I don't get the firebase has no exported member 'Promise error. The specific error message for that error is:

ERROR in /home/circleci/repo/node_modules/angularfire2/firebase.app.module.d.ts (12,28): Namespace 'firebase' has no exported member 'Promise'.

I'm not sure why there is a difference between yarn and npm, but I hope this helps

Charlie

@CharlesSuttie
yarn add angularfire2 5.0.0-rc3 should be yarn add angularfire2@5.0.0-rc3 instead.

If you have rc.0-next you will get the error. rc.2 and above should be fine.

[lastamazing7]

when update
the version of angularfire2 in my local node_modules: it's 5.0.0-rc.0-next.
then getting this error :

node_modules/angularfire2/database/index"' has no exported member 'FirebaseListObservable'

I don't want to upgrade to v5. How does one stay on 4.0.0-rc.0 (or 1,2)? Is there an actual working v4 anymore?
