Angular 5 + Firebase: Namespace 'firebase.auth' has no exported member 'IdTokenResult'

Question

I am currently work on web project using Angular 5 and I want to integrate the Firebase Cloud Messaging to send notification on app, bt I faced to a lot of problems that I tried to fix them. Right now there two errors that I'm not able to fix concerning: Namespace 'firebase.auth' and functions

The errors look like:

ERROR in node_modules/angularfire2/auth/auth.d.ts(12,45): error TS2694: Namespace 'firebase.auth' has no exported member 'IdTokenResult'.
node_modules/angularfire2/firebase.app.module.d.ts(2,42): error TS2305: Module '"/Users/gerardtalla/dev/workspaces/ws-parcaune/pms/pms-frontend-2018/node_modules/firebase/app/index"' has no exported member 'functions'.

How can I fix that? I'm using

Angular 5

"firebase": "4.8.0"

"angularfire2": "^5.0.0-rc.5"

"@angular/cli": "~1.7.3"

if someone has an idea do not hesitate please share with me. Thank a lot in advance.

Answer 2

just use "angularfire2": "5.0.0-rc.5" instead of "angularfire2": "^5.0.0-rc.5"

when I used "angularfire2": "5.0.0-rc.5" I got this error by running npm install : npm ERR! code ETARGET npm ERR! notarget No matching version found for [email protected] npm ERR! notarget In most cases you or one of your dependencies are requesting npm ERR! notarget a package version that doesn't exist. npm ERR! notarget npm ERR! notarget It was specified as a dependency of 'pms-frontend-2018' npm ERR! notarget – Inflict

Run the following command:

npm i --save firebase@latest   angularfire2@latest

It will not work. It is always better to mention the package version, so in the future, app builds does not break – Kilogrammeter

Answer 4

"angularfire2": "5.0.0-rc.6", "firebase": "4.9.0",

I resolve this issue by making this change in package.json.
