Angular 4与AngularFire2

Question

我正在尝试在Angular 4中设置一个新网站。我想使用Firebase作为数据库后端。

我使用的是安装指南这里找到：https://github.com/angular/angularfire2/blob/master/docs/1-install-and-setup.md

然而，当我执行ng serve --open我收到此错误：

ERROR in Error encountered resolving symbol values statically. Calling function 'OpaqueToken', function calls are not supported. Consider replacing the function or lambda with a reference to an exported function, resolving symbol FirebaseUserConfig in C:/Source/node_modules/angularfire2/tokens.d.ts, resolving symbol AngularFireModule.initializeApp in C:/Source/node_modules/angularfire2/angularfire2.d.ts, resolving symbol AppModule in C:/Source/src/app/app.module.ts, resolving symbol AppModule in C:/Source/src/app/app.module.ts

正如我宁愿用角一个新手，我不知道如何解决这个错误。
