无法从'jasmine-marbles.umd.js'找到模块'rxjs/testing'

Question

我目前想用ngrx/effects测试我的效果.我跟着降价,但是当我想要运行我的测试时我有一个错误.

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

这是我的代码(目前我没有做到期望,我只想要我的测试运行):

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 })
    })
}

这是我的package.json的样子:

  [...]
  "dependencies": {
    [... all @angular import ...]
    "@ngrx/effects": "^5.2.0",
    "@ngrx/store": "^5.2.0",
    "@ngrx/store-devtools": "^5.2.0",

    "rxjs": "^5.5.6",
    "zone.js": "^0.8.19"
  },
  "devDependencies": {
    "@angular/cli": "1.6.7",
    "@angular/compiler-cli": "^5.2.0",
    "@angular/language-service": "^5.2.0",
    "@types/jest": "^22.1.4",
    "@types/node": "~6.0.60",
    "codelyzer": "^4.0.1",
    "jasmine-marbles": "^0.3.0",
    "jest": "^22.4.2",
    "jest-junit": "^3.6.0",
    "jest-preset-angular": "^5.2.0",
    "ts-node": "~4.1.0",
    "tslint": "~5.9.1",
    "typescript": "~2.5.3"
  }
  [...]

有谁可以帮我解决这个问题？

刚刚碰到这个.

在我的情况下,使用jasmine-marbles@v0.2.0而不是@latest解决它,因为它似乎不需要beta rxjs 6发布的对等依赖
