我跟随Angular的Tour of Heroes tutorial。在最后一部分“HTTP”中，当添加“角存储器web-api”时，我得到一个空白页。该终端不显示任何错误消息，但我得到了浏览器的控制台上的消息：英雄之旅教程与“角内存网络-API”教程问题

这里是我的package.json：

这是我的systemjs.config.js：

*/
(function (global) {
System.config({

},
// map tells the System loader where to look for things

// packages tells the System loader how to load when no filename and/or no extension
packages: {
app: {
main: './main.js',
defaultExtension: 'js'
},
rxjs: {
defaultExtension: 'js'
},
'angular-in-memory-web-api': {
main: './index.js',
defaultExtension: 'js'
}
}
});
})(this);
我我们看过其他SO问题，如this one，但他们没有相同的问题，也没有提供我的解决方案。看起来他们使用旧版本的教程。看来“角度在内存中的web-api”已经有点麻烦了一段时间了。
任何帮助，将不胜感激！
