在全新安装ng new myapp(cli 版本 1.6.8、Angular 5.2.0、rxjs 5.5.6)时,我安装了 rxjs 弹珠。

由于某些配置原因,我在运行非常基本的测试时遇到问题。谁能告诉我出了什么问题?

import { TestBed, async } from '@angular/core/testing';
import { marbles } from 'rxjs-marbles/jasmine';
import { map } from 'rxjs/operators';
import { AppComponent } from './app.component';

describe('AppComponent', () => {
  beforeEach(async(() => {
    TestBed.configureTestingModule({
      declarations: [
        AppComponent,
      ],
    }).compileComponents();
  }));

  it('should see mapped values', marbles(m => {
    const values = { a: 1, b: 2, c: 3, x: 2, y: 4, z: 6 };

    const source = m.cold('--a---b---c-|', values);
    const expected = m.cold('--x---y---z-|', values);
    const result = source.pipe(map(x => x * 2));
    m.expect(result).toBeObservable(expected);
  }));
});

控制台错误:

rxjs-marbles 版本 3 和更高版本依赖于 RxJS 版本 6

如果您使用的是 RxJS 版本 5,则需要使用rxjs-marbles版本 2,其最新版本是2.4.1.

如果您使用该版本,对于文档,您应该参考该版本分支中的 README,而不是master.
