最近看到一篇用Visual Studio Code开发Angular2的文章，也是一篇入门教程，地址为：使用Visual Studio Code開發Angular 2專案。这里按部就班的做了一遍，感觉很方便，并且没有遇到楼主的一些问题，应该是安装环境有些不同。这里只为记录一下。再次感谢！
一、随便新建一个目录，这里为：F:\Visual Studio Code\angular2_1，并用Visual Studio Code
二、依次新建如下四个文件，参考https://angular.cn/docs/ts/latest/quickstart.html
package.json 用来标记出本项目所需的 npm 依赖包。
tsconfig.json 定义了 TypeScript 编译器如何从项目源文件生成 JavaScript 代码。
typings.json 为那些 TypeScript 编译器无法识别的库提供了别的定义文件。
systemjs.config.js 为模块加载器提供了该到哪里查找应用模块的信息，并注册了所有必备的依赖包。 它还包括文档中后面的例子需要用到的包。

(function (global) {
System.config({
paths: {
// paths serve as alias
'npm:': 'node_modules/'
},
// map tells the System loader where to look for things
map: {
// our app is within the app folder
app: 'app',
// angular bundles

},
'angular-in-memory-web-api': {

}
}
});
})(this);
systemjs.config.js
三、按着“shift”键，右键项目文件夹，选择“在此处打开命令窗口（W）”，键入DOS命令窗口，键入”npm install“,截图如下：
下载了好多文件，依赖的类库可真多，之后的文件夹目录如下：
四、在根目录下新建app文件夹，并依次创建下面三个文件app.module.ts、app.component.ts、main.ts;并在根目录下新建html页面——index.html
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
@NgModule({
imports: [ BrowserModule ],
declarations: [ AppComponent ],
bootstrap: [ AppComponent ]
})
export class AppModule { }
app.module.ts
import { Component } from '@angular/core';
@Component({
selector: 'my-app',
template: '<h1>My First Angular App</h1>'
})
export class AppComponent { }
app.component.ts
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { AppModule } from './app.module';
const platform = platformBrowserDynamic();
platform.bootstrapModule(AppModule);
main.ts
<html>
<head>
<title>Angular QuickStart</title>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="styles.css">
<!-- 1. Load libraries -->
<!-- Polyfill(s) for older browsers -->
<script src="node_modules/core-js/client/shim.min.js"></script>
<script src="node_modules/zone.js/dist/zone.js"></script>
<script src="node_modules/reflect-metadata/Reflect.js"></script>
<script src="node_modules/systemjs/dist/system.src.js"></script>
<!-- 2. Configure SystemJS -->
<script src="systemjs.config.js"></script>
<script>
System.import('app').catch(function(err){ console.error(err); });
</script>
</head>
<!-- 3. Display the application -->
<body>
<my-app>Loading...</my-app>
</body>
</html>
index.html
五、按照如下截图，设定启动作业：
设置成功之后，在启动文件launch.json中做如上图修改：${workspaceRoot}/node_modules/lite-server/bin/lite-server
六、在菜单栏中，点击”查看“/”命令面板“或者快捷键”cltr+shift+p“,键入”configure“，选择”任务：配置任务运行程序“，之后选择”TypeScript-tsconfig.json 创建TypeScript项目“，如下图：
按照教程博客所说，要task.json做如上图修改，否则下面调试时如果出现错误没有任何提示。
七、以上已经完成了所有的工作，开始调试。按下”ctrl+shift+b“,执行编译，会将ts文件编译为js文件，如下图：
如果编译成功（如上图），就可以按”F5“了，如下图：
但是如果编译不成功，应该是没有安装tsc,使用命令”npm install -g typescript“安装一下，之后再编译就没问题了，如下图：
这里完全是按着上面的教程来的，有点不好意思，只作为练习记录，再次感谢!
