Answer 1

angularfire2 v5.0.0-rc.3正在使用rxjs 5.x。你有两种方式。

1：升级AngularFire2 Libary。

npm install --save angularfire2@latest

，或者

2：安装rxjs-compat

npm install --save rxjs-compat

Answer 2

update
angularfire2包已被弃用，现在您不应该使用它。
新软件包的名称为@angular/fire。
而且npm install --save angularfire2@latest 也不是解决方案，因为您可以直接安装并使用它，但该问题已被取消，并且也没有提供支持。
您可以使用npm install --save rxjs-compat弃用版本来解决此错误。

有关最新版本，请使用npm install @angular/fire
