Angularjs 失败：没有反射器的提供程序！在带有karma的angular2中运行测试时出错

在尝试重构我的测试时，我使用TestComponentBuilder来遵守angular2.0.0-beta.2（目前使用angular2.0.0-beta.6）中所做的突破性更改，在遵循更改日志中指定的说明时，我最终得到了以下结果：

import{
  it,
  xit,
  expect,
  describe,
  injectAsync,
  TestComponentBuilder,
  setBaseTestProviders
} from 'angular2/testing';

import {
  TEST_BROWSER_PLATFORM_PROVIDERS,
  TEST_BROWSER_APPLICATION_PROVIDERS
} from 'angular2/platform/testing/browser';

import {Component} from "angular2/core";

@Component({
  selector: 'nope',
  template: `hello`,
})
class SimpleComponent {
  sayHello() {
    return "hello"
  }
}

describe('Simple Component', () => {
  setBaseTestProviders(TEST_BROWSER_APPLICATION_PROVIDERS, TEST_BROWSER_PLATFORM_PROVIDERS);

  it('should recognize a simple component', () => {
    expect(SimpleComponent).not.toBeNull();
    expect(SimpleComponent).not.toBeUndefined();
  });

  it('should get response from sayHello method', () => {
    const simpleComponent = new SimpleComponent();
    expect(simpleComponent.sayHello()).toEqual("hello")
  });

  it('should render simple component', injectAsync([TestComponentBuilder], (tcb:TestComponentBuilder) => {
    return tcb.createAsync(SimpleComponent).then(fix => {
      fix.detectChanges()
      const compiled = fix.debugElement.nativeElement;

      expect(compiled).toBeDefined();
    })
  }));
});

使用TestComponentBuilder的最终测试失败，出现以下错误和堆栈跟踪：
