所以，我已经尝试学习Angular 2了几天（Github Repo）。对于单元测试，我一直在尝试配置Jasmine和Karma. 我一直在关注这些项目作为基础

1)使用 Karma 和 Jasmine 测试 Angular 2

2）种子Angular2应用

但是，由于某些原因，我没有正确配置。可能是由于缺乏前端开发经验。

首先，我收到消息错误：

node_modules/angular2/platform/browser.d.ts(77,90): error TS2304: Cannot find name 'Promise'.

我在这里发现了类似的问题， 并按照此处提到的解决方案进行了操作

但是现在我收到以下错误：

node_modules/rxjs/Observable.d.ts(1,1): error TS2654: Exported external package typings file cannot contain tripleslash references. Please contact the package author to update the package definition.
node_modules/rxjs/Observable.d.ts(12,6): error TS2304: Cannot find name 'Symbol'.
node_modules/rxjs/Observable.d.ts(15,42): error TS2304: Cannot find name 'Iterable'.

对于这个错误，我没有找到任何令人信服的解决方案。那么，有人可以帮我解决这个问题吗？

提前致谢。

这是 rxjs bet 5 中的一个错误。等待 beta 6 或降级到 4 使用

 npm install rxjs@5.0.0-beta.4 --save.

您需要在您的应用程序入口点中引用定义文件：

/// <reference path="node_modules/angular2/typings/browser.d.ts" />
