404 GET/app - Angular2快速入門

我正嘗試將基於舊的angular2快速入門的應用程序遷移到新的（具有新的文件夾層次結構）。404 GET/app - Angular2快速入門

當打到npm start我得到404 GET /app錯誤。它一提的是我的app.module.ts文件/app/modules/app/app.module.ts

下放在我試圖改變沒有運氣路徑，但我還是懷疑，它的東西，是關係到我的配置是很重要的。

main.ts：

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic'; 

import { AppModule } from './app/modules/app/app.module'; 

platformBrowserDynamic().bootstrapModule(AppModule);

systemjs.config.js：

/** 
* System configuration for Angular samples 
* Adjust as necessary for your application needs. 
*/ 
(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' 
     }, 
     rxjs: { 
     defaultExtension: 'js' 
     } 
    } 
    }); 
})(this);

的index.html：

<!DOCTYPE html> 
<html> 
    <head> 
    <base href="/"> 
    <title>Tic Tac Toe</title> 
    <meta charset="UTF-8">

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

    <body> 
    <my-app>Loading AppComponent content here ...</my-app> 
    </body> 
</html>

更改systemjs.config.js

在package項改變app到app: {main: 'app/modules/app/app.module', defaultExtension: 'js'}

如果你有地方創建了應用的捆綁，你應該指向app關鍵該捆綁而不是app.module。

其實只是：應用：{main：'modules/app/app.module'，defaultExtension：'js'} – ohadinho
