Angular2 DI 错误没有 EventEmitter 的提供者

Question

我在尝试启动 Angular2 应用程序时遇到运行时问题：

EXCEPTION: No provider for EventEmitter!

Error: DI Error at NoProviderError.ZoneAwareError (localhost/js/polyfills.js:4666:33) at NoProviderError.BaseError [as constructor] (localhost/js/vendor.js:11730:16) at NoProviderError.AbstractProviderError [as constructor] (localhost/js/vendor.js:77033:16) at new NoProviderError (localhost/js/vendor.js:77082:16) at ReflectiveInjector_.throwOrNull (localhost/js/vendor.js:123981:19) at ReflectiveInjector.getByKeyDefault (localhost/js/vendor.js:124018:25) at ReflectiveInjector.getByKey (localhost/js/vendor.js:123968:25) at ReflectiveInjector.get (ocalhost/js/vendor.js:123730:21) at AppModuleInjector.get (/AppModule/module.ngfactory.js:213:131) at AppModuleInjector.getInternal (/AppModule/module.ngfactory.js:688:61) at AppModuleInjector.NgModuleInjector.get (localhost/js/vendor.js:77948:44) at CompiledTemplate.proxyViewClass.AppView.injectorGet (localhost/js/vendor.js:124739:45) at CompiledTemplate.proxyViewClass.View_AppComponent_Host0.createInternal (/AppModule/AppComponent/host.ngfactory.js:15:173) at CompiledTemplate.proxyViewClass.AppView.createHostView (localhost/js/vendor.js:124695:21)

但我不知道它来自哪里...

这是我的 tsconfig:

{
  "compilerOptions": {
    "target": "ES5",
    "module": "commonjs",
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "sourceMap": true,
    "noEmitHelpers": true,
    // option for momentjs compilation
    "allowSyntheticDefaultImports": true
  },
  "compileOnSave": false,
  "buildOnSave": false,
  "awesomeTypescriptLoaderOptions": {
    "forkChecker": true,
    "useWebpackText": true
  },
  "exclude": [
    "node_modules",
    "dist",
    "src/custom-typings",
    "typings/index.d.ts",
    "typings/globals/core-js/index.d.ts",
    "typings/globals/node/index.d.ts",
    "typings/globals/jasmine/index.d.ts"
  ]
}

我正在使用 'awesome-typescript-loader'、'angular2-template-loader'、'angular2-router-loader'。

有什么想法吗？

我找到问题了！ Chrome 没有显示好的信息... Firefox 和 IE 指出导致问题的服务 SlimLoadingBarService。

然后我看到它是在 github 上注册的： https://github.com/akserg/ng2-slim-loading-bar/issues/32

感谢 Günter 编辑 post。下次怎么自己做？
