I assume your App is an Ionic 3 app?

Yoo need to downgrade ‘rxjs’:

  "dependencies": {
    "@angular/common": "5.0.3",
    "@angular/compiler": "5.0.3",
    "@angular/core": "5.0.3",
    "@angular/forms": "5.0.3",
    "@angular/http": "5.0.3",
    "@angular/platform-browser": "5.0.3",
    "@angular/platform-browser-dynamic": "5.0.3",
     ...
    "angularfire2": "^5.0.0-rc.6.0",
