SystemJS core_1.provide 不是函数

Question

我尝试设置 ASP.NET MVC 5（非核心）+ Angular 2.0.0 + JSPM + SystemJS + TS Loader。

在我看来，TS 加载器可能有问题。有什么建议吗？

当我运行应用时出现错误：

Error: (SystemJS) core_1.provide is not a function
    TypeError: core_1.provide is not a function
        at execute (http://localhost:59711/app/bootstrap.ts!transpiled:26:24)
    Error loading http://localhost:59711/app/bootstrap.ts

这是我的配置文件：

tsconfig.json

{
  "compilerOptions": {
    "target": "es5",
    /* target of the compilation (es5) */
    "module": "system",
    /* System.register([dependencies], function) (in JS)*/
    "moduleResolution": "node",
    /* how module gets resolved (needed for Angular 2)*/
    "emitDecoratorMetadata": true,
    /* needed for decorators */
    "experimentalDecorators": true,
    /* needed for decorators (@Injectable) */
    "noImplicitAny": false
    /* any has to be written explicity*/
  },
  "exclude": [
    /* since compiling these packages could take ages, we want to ignore them*/
    "jspm_packages",
    "node_modules"
  ],
  "compileOnSave": false
  /* on default the compiler will create js files */
}

config.js（jspm，配置文件已简化）

System.config({
  baseURL: "/",
  defaultJSExtensions: true,
  transpiler: "babel",
  babelOptions: {
    "optional": [
      "runtime",

检查版本 2.0.0-rc.6 的更改日志：

core: remove deprecated provider/bind API

不再接受这些形式的提供商：

bind(MyClass).toFactory(...)
new Provider(MyClass, toFactory: ...)

现在唯一接受的形式是：

{provide: MyClass, useFactory: ...}

Angular2 的最终版本也需要 NgModule。如果您使用最终的 Angular2 v2.0.0，您的应用程序就是这样正确的。看一看 Quick Start Guide 看看应该如何引导应用程序！
