Angular: rxjs“rxjs”中缺少 flatMap：“5.0.0-beta.2”

我曾尝试在 angular2 中执行 flatMap 函数，但它显示错误，因为 flatMap 不是函数，并且

ERROR in ./src/app/services/login-refresh-token-services.ts
(155,40): error TS2339: Property 'flatMap' does not exist on type 'Subscription'.

我检查了 rxjs/rx 文件。 没有这样的数据 flatMap。 因此，据我所知，缺少 rxjs flatmap 运算符
