Question

我正在使用mvc .Net结合最新的角度（5.2.10）。问题是我无法启动和运行Angular。

Angular app文件位于＆＃39; app＆＃39;夹。＆＃39; _Layout.cshtml＆＃39;位于内部视图/共享文件夹中。

_Layout.cshtml：

<!DOCTYPE html>
<html>
<head>
   <base href="/" />
   <meta charset="utf-8">
   <meta http-equiv="X-UA-Compatible" content="IE=edge">

   <!-- Polyfill(s) for older browsers -->
   <script type="text/javascript" src="~/node_modules/core-js/client/shim.min.js"></script>
   <script type="text/javascript" src="~/node_modules/zone.js/dist/zone.js"></script>
   <script type="text/javascript" src="~/node_modules/systemjs/dist/system.src.js"></script>

   <script type="text/javascript" src="~/systemjs.config.js"></script>
   <script type="text/javascript">
    System.import('app/main.js').catch(function (err) { console.error(err); });
</script>

</head>

<body>           
   <div>    
       @RenderBody()
   </div>
</body>
</html>

systemjs.config.js：

  (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/core': 'npm:@angular/core/bundles/core.umd.js',
  '@angular/common': 'npm:@angular/common/bundles/common.umd.js',
  '@angular/compiler': 'npm:@angular/compiler/bundles/compiler.umd.js',
  '@angular/platform-browser': 'npm:@angular/platform-browser/bundles/platform-browser.umd.js',
  '@angular/platform-browser-dynamic': 'npm:@angular/platform-browser-dynamic/bundles/platform-browser-dynamic.umd.js',
  '@angular/http': 'npm:@angular/http/bundles/http.umd.js',
  '@angular/router': 'npm:@angular/router/bundles/router.umd.js',
  '@angular/forms': 'npm:@angular/forms/bundles/forms.umd.js',

  // other libraries
  'rxjs':                      'npm:rxjs',
  'angular-in-memory-web-api': 'npm:angular-in-memory-web-api/bundles/in-memory-web-api.umd.js'
},
// packages tells the System loader how to load when no filename and/or no extension
packages: {
  app: {
    defaultExtension: 'js',
    meta: {
      './*.js': {
        loader: "systemjs-angular-loader.js"
      }
    }
  },
  rxjs: {
          defaultExtension: 'js'
        }
     }
  });
  })(this);

我得到的错误是：

Error: Fetch error: 404 Not Found (systemjs-angular-loader.js)
  Instantiating http://www.nlgdevelopment.com/systemjs-angular-loader.js
  Loading http://www.nlgdevelopment.com/systemjs-angular-loader.js

     at ZoneDelegate.invokeTask (zone.js:421)
     at Zone.runTask (zone.js:188)
     at drainMicroTaskQueue (zone.js:595)

＆＃39; Systemjs-角loader.js＆＃39;和＆＃39; systemjs.config.js＆＃39;文件位于同一级别（根路径）。我遵循了官方Angular网站提供的快速入门指南，但出了点问题。

如果这是一个新项目，我建议使用dot net命令删除它并开始一个新项目：

dotnet new angular -o my-new-app

这将使用Angular CLI生成您的应用。基本上，您的MVC应用程序根本不包含任何“Views”文件夹，甚至不包含_Layout.cshtml页面。所有客户端逻辑和模板都存储在“Client App”文件夹中。
