我根据本教程尝试为TypeScript安装Angular 2:https://angular.io/guide/quickstart

我收到这个错误:

ReferenceError:系统未定义System.config

我不知道这是怎么回事.

文件夹结构:

project
|-index.hml
|-assets
    |-js
    |- jquery
    |-app
       |-app.component.js
       |-app.component.ts
       |-app.component.js.map
       |-main.js
       |-main.ts
       |-main.js.map

我有以下 json：

"rates": {
        "AT": {
            "country": "Austria",
            "standard_rate": 20.00,
            "reduced_rate": 10.00,
            "reduced_rate_alt": 13.00,
            "super_reduced_rate": false,
            "parking_rate": 12.00
        },
        "DK": {
            "country": "Denmark",
            "standard_rate": 25.00,
            "reduced_rate": false,
            "reduced_rate_alt": false,
            "super_reduced_rate": false,
            "parking_rate": false
        },
}

我有以下类来反序列化 json：

    public string country { get; set; }
    public double standard_rate { get; set; }
    //public string reduced_rate { get; set; }
    private double _reduced_rate;

    public double reduced_rate
    {
        get { return _reduced_rate; }
        set
        {
            bool isDouble = Double.TryParse(value.ToString(), out _reduced_rate);
            if (isDouble) …
