Cannot find module 'rxjs/testing' from 'jasmine-marbles.umd.js' - rxjs

Question

I am currently want to test my effects with ngrx/effects. I followed the markdown but I have an error when I want run my test.
Cannot find module 'rxjs/testing' from 'jasmine-marbles.umd.js'
Here is my code (For the moment I did not do expectations, I just want my test runs) :
import { TestBed } from '#angular/core/testing'
import { provideMockActions } from '#ngrx/effects/testing'
import { ReplaySubject } from 'rxjs/ReplaySubject'
import { hot, cold } from 'jasmine-marbles'
import { Observable } from 'rxjs/Observable'
import { VersionService } from '../../service/version/version.service'
import { DataEffects } from './data.effect'
import { RequestVersions, ReceiveVersions } from './data.action'
describe('My Effects', () => {
let versionService: VersionService
let effects: DataEffects
let actions: Observable<any>
beforeEach(() => {
TestBed.configureTestingModule({
imports: [
// any modules needed
],
providers: [
DataEffects,
provideMockActions(() => actions),
{provide: VersionService, useValue: {
getVersions: jest.fn().mockReturnValueOnce({data: {versions: 'MOCKED_VERSION_RESULT'}})
}}
],
})
versionService = TestBed.get(VersionService)
effects = TestBed.get(DataEffects)
})
it('should work', () => {
const action = new RequestVersions()
const completion = new ReceiveVersions('MOCKED_VERSION_RESULT')
actions = hot('--a-', { a: action });
const expected = cold('--b', { b: completion })
})
}
And here what my package.json look like :
[...]
"dependencies": {
[... all #angular import ...]
"#ngrx/effects": "^5.2.0",
"#ngrx/store": "^5.2.0",
"#ngrx/store-devtools": "^5.2.0",

"zone.js": "^0.8.19"
},

"jest-preset-angular": "^5.2.0",
"ts-node": "~4.1.0",
"tslint": "~5.9.1",

}
[...]
Can anyone help me in this matter ?

Just ran into this as well.
In my case using jasmine-marbles#v0.2.0 instead of the #latest resolve it, since it doesn't seem to require the peer dependency of the beta rxjs 6 release
