Angular 泛型'；观察员<；五、 E>'；需要2个类型参数@firebase/应用程序类型/专用d.ts

我正在尝试创建一个使用angularfire2的firebase应用程序。但我得到了以下错误：

打字错误 泛型类型“Observer”需要2个类型参数。 …node_modules/@firebase/app types/private.d.ts

• 将服务名称转换为要使用的工厂名称。 */ UseAService（app:FirebaseApp，serviceName:string）：string | null

这是我的package.json文件

试试这个

npm安装angularfire2@5.0.0-rc.6.0——保存

npm安装firebase@4.12.1

相同的错误并添加了新错误。。。。。类“FirebaseApp”不正确地实现了接口“FirebaseApp”。类型“FirebaseApp”中缺少属性“automaticDataCollectionEnabled”。面临相同问题。您找到解决方案了吗？没有，我还没有解决方案。更新到@latest后，这里出现了相同的问题。您找到解决方案了吗？更新到5.0.3为我解决了问题。npm i@firebase/util为我解决了问题
