Error:(4,37) TS2503: Cannot find namespace ‘jasmine’.

安装了NPM模块,typescript编译器运行良好.
怎么了？

myservice.serviceSpec.ts：

import {it,describe,expect,beforeEach,inject} from 
'angular2/testing';
import {myService} from "../app/myservice.service";

describe('Tests',() => {
    it('should be true',() => {
        expect(true).toBe(true);
    });
});

的package.json：

  }
}

tsconfig.json：
