Error Angularfire2 TS2305

Question

I am new to the world of ion frames, and now I'm trying to create an application for a school project. To save data in the application, I will use firebase (for the first time). I am trying to import Angularfire and FirebaseListObservable into my .ts file, but I get this error message:

"TS2305: Module" 'C: / Users / matss / myRecords / node_modules / angularfire2 / index "' does not have an exported member 'AngularFire'.

Here is my import in app.module.ts

import { AngularFireModule } from 'angularfire2;

export const firebaseConfig = {
apiKey: "blablabla",
authDomain: "blablabla",
databaseURL: "blablabla",
projectId: "blablabla",
storageBucket: "blablabla",
messagingSenderId: "blablabla"
};

here is my code in excersises.ts that gives errormessage:

import { AngularFire, FirebaseListObservable } from 'angularfire2';

  constructor(private navParams: NavParams, public nacCtrl: NavController, af: AngularFire){
this.records = af.database.list('/records');

}
