我试图从Angular 5迁移到Angular 6 ..然后我们都知道..其他一切依赖于其他所有包..我最终需要更新firebase包：
npm install -s firebase@latest
然后这是我运行ng serve时的错误
node_modules/@firebase/app-types/private.d.ts中的错误（130,28）：错误TS2314：通用类型'Observer'需要2个类型的参数。
node_modules/@firebase/app-types/private.d.ts(131,34）：错误TS2314：通用类型'Observer'需要2个类型的参数。

这是我的package.json：

这是我们可以在文件node_module/@firebase/app-types/private.d.ts(130,28）中看到的：
/**
* Create a Subscribe function. A proxy Observer is created so that
* events can be sent to single Observer to be fanned out automatically.
*/
createSubscribe<T>(
executor: (observer: Observer<T>) => void,
onNoObservers?: (observer: Observer<T>) => void
): Subscribe<T>;
如何在不降级我的Firebase软件包的情况下使其工作？
更新typescript，npm install [email protected] --save将修复错误。
