Angularfire2错误TS2305(Angularfire2 error TS2305)

 我是离子框架世界的新手，现在我正在尝试为学校项目创建一个应用程序。 要在应用程序中保存数据，我将使用firebase（第一次）。 我尝试将Angularfire和FirebaseListObservable导入我的.ts文件，但是我收到此错误消息： 
 
 “TS2305：模块”'C：/ Users / matss / myRecords / node_modules / angularfire2 / index“'没有导出成员'AngularFire'。 
 
 这是我在app.module.ts中的导入 
 
import { AngularFireModule } from 'angularfire2;

export const firebaseConfig = {
apiKey: "blablabla",
authDomain: "blablabla",
databaseURL: "blablabla",
projectId: "blablabla",
storageBucket: "blablabla",
messagingSenderId: "blablabla"
};
 
 这是我在excersises.ts中的代码，它给出了错误消息： 
 
import { AngularFire, FirebaseListObservable } from 'angularfire2';

  constructor(private navParams: NavParams, public nacCtrl: NavController, af: AngularFire){
this.records = af.database.list('/records');
 
 } 
 
 作为一个新手，我没有找到任何“好”的教程，我可能会在我的搜索中使用错误的关键字..但是为此我遵循了这个教程： https ： //www.joshmorony.com/building-a-污物离子-2-应用与-火力-angularfire / 
 
 谢谢你的帮助。 

I'm new to the ionic framework world and now I'm trying to create a app for a schoolproject. To save data in the app I'll be using firebase (for the first time). I try to import Angularfire and FirebaseListObservable to my .ts file but i get this error message:
 
"TS2305:Module "'C:/Users/matss/myRecords/node_modules/angularfire2/index"' has no exported member 'AngularFire'.
 
Here's 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's my code in excersises.ts, which gives the errormessage:
 
import { AngularFire, FirebaseListObservable } from 'angularfire2';

  constructor(private navParams: NavParams, public nacCtrl: NavController, af: AngularFire){
this.records = af.database.list('/records');
 
}
 
As a rookie to this, I haven't found any "good" tutorials, I might use the wrong keywords in my searches.. But for this I followed this tutorial: https://www.joshmorony.com/building-a-crud-ionic-2-application-with-firebase-angularfire/
 
Thanks for your help.
