same thing here from 1.7.4 to r.c.4

https://github.com/angular/angular-cli/issues/10336 seems to be the same as this one. It looks to be related or caused by [email protected], and happens on new projects as well.

This seems to be the issue on rxjs https://github.com/ReactiveX/rxjs/issues/3573.

Hi. I commented on the RxJS issue - https://github.com/ReactiveX/rxjs/issues/3573 - to point out that the issue's snippet contained an error. There is a similar error in this file and the result of a call to the reduce pipeable operator is passed to concat.

[cyrilletuzi]

As a temporary workaround: npm install [email protected]

Hi @cartant, thank you for letting us know what the problem is!
