Angular Firestore Update v 5.2.1 issue - Ionic 4

Hi everyone,

I wanted to update my @angular/fire to use new features of firestore. When i update the latest version of firebase, I got some high vulnerabilities. It asks me to update the @angular/devkit , @angular/cli/core, karma etc.
When i do these updates and run ionic cordova run browser, i receive an errorr which says @angular/compiler-cli/ngcc not found. I checked node_modules and it is there.

I am not sure if this is related to that ionic not compatible with latest angular 8 at the moment.

Has anyone recently updated to the latest version of angular/fire without any issue?

Before the error, my package.jason details are as below.
@angular/common”: “^7.1.4”,
@angular/core”: “^7.1.4”,
@angular/fire”: “^5.1.1”,
@ionic-native/firebase-authentication”: “^4.20.0”,
@ionic-native/core”: “^5.0.0”,
@ionic/angular”: “^4.1.1”,
“rxjs”: “~6.3.3”,
@angular-devkit/build-angular”: “^0.12.3”,
@angular-devkit/core”: “~7.1.4”,
“karma”: “~3.1.4”,
“typescript”: “~3.1.6”

Thanks a lot,
