Javascript 找不到名称'；承诺'；使用'时出错；npm启动'；命令

我是新来的。我完成了教程并继续尝试这个。我只是尝试使用与示例中相同的代码。通过

npm install

安装节点模块后运行

npm start

命令时，我收到以下异常

[system]:~/Coding/Angular2/SecondApp$ npm start

在StackOverFlow中尝试了一些建议，但没有任何帮助。

正如您的项目结构所示，没有

打字文件夹，您在第一个示例中遗漏了它

npm安装后无法显示typings文件夹。如果是，请手动安装。

npm run typings install

这应该可以解决问题。
谢谢您的帮助：）
