This can help (using rxjs 5.5.3 - “rxjs”: “^5.5.2”)

Bug with empty path:

const routes: Routes = [ { path: “”, component: SynthesisComponent }, { path: “home”, component: SynthesisComponent }, { path: “about”, component: AboutComponent }, … ];

Ok when using pathMatch: ‘full’:

const routes: Routes = [ { pathMatch: ‘full’, path: “”, component: SynthesisComponent }, { pathMatch: ‘full’, path: “home”, component: SynthesisComponent }, { pathMatch: ‘full’, path: “about”, component: AboutComponent }, … ];

Me too with an Angular 5.0.5 project. After downgrading rxjs to 5.5.2 the problem went away.

After an update of my angular project I get the same error. In my case, routing with children and outlets doesn’t work.

Fixed this issue in my setup by changing rxjs from ^5.4.2 to 5.5.2.

ajmarmar on Dec 2, 2017

Experiencing the same thing. Had to fix rxjs version in package.json to prevent CI from installing version 5.5.3: "rxjs": "5.5.2"

update to 5.5.5 is ok.

We have added quick fix for this and patch will be released soon.

5.5.4 works

kingo999 on Dec 6, 2017

FYI: In react project, v5.5.3 upgrade also breaking app. In this case import Rx from 'rxjs/Rx' is returning undefined; producing TypeError: Cannot read property 'Subject' of undefined. This was functioning fine prior to to this minor release.

I was able to get it working, thank you @beeman

mmanavaz on Dec 8, 2017

Tried 5.5.5 as you suggested- still getting the same error…

See Angular issue #20752 for a minimal reproduction of the problem.
