带有ng-bootstrap 404错误的Angular2 RC5入门 [英] Getting started Angular2 RC5 with ng-bootstrap 404 Error

问题描述

我已经按照ng-bootstrap网站上的说明进行了安装，并使用了Angular2的新git克隆，但是当NgbModule在@NgModule的导入数组中时收到404错误.

I have followed the instructions for installation on the ng-bootstrap website with a fresh git clone of Angular2, but receive a 404 Error when NgbModule is in the import array of @NgModule.

错误的屏幕截图: 404加载@ ng-bootstrap时出错

步骤:

1. 克隆Angular2的快速入门git repo github.com/angular/quickstart

2. 将app.module.ts编辑为以下内容:

import { NgModule }      from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';

import { AppComponent }  from './app.component';
import { NgbModule } from "@ng-bootstrap/ng-bootstrap";

@NgModule({
  imports: [ NgbModule, BrowserModule ],
  declarations: [ AppComponent ],
  bootstrap: [ AppComponent ]
})
export class AppModule { }

确保已安装bootstrap@4.0.0-alpha.3，ng-bootstrap和angular2 RC5

Make sure bootstrap@4.0.0-alpha.3, ng-bootstrap and angular2 RC5 are installed

尝试通过node_module显式设置导入路径时，也会发生同样的情况. import { NgbModule } from "../node_modules/@ng-bootstrap/ng-bootstrap";

The same occurs when trying to set the import path explicitly through node_module eg. import { NgbModule } from "../node_modules/@ng-bootstrap/ng-bootstrap";

任何帮助表示赞赏.

在项目根文件 systemjs.config.js 中添加了@ ng-bootstrap行.浏览器控制台中出现类似的404错误.

Added @ng-bootstrap line to project root file systemjs.config.js. Similar 404 error in browser console.

systemjs.config.js :

/**
 * System configuration for Angular 2 samples
 * Adjust as necessary for your application needs.
 */
(function(global) {

  // map tells the System loader where to look for things
  var map = {
    'app':                        'app', // 'dist',

    '@ng-bootstrap':              'node_modules/@ng-bootstrap',
    '@angular':                   'node_modules/@angular',
    'angular2-in-memory-web-api': 'node_modules/angular2-in-memory-web-api',
    'rxjs':                       'node_modules/rxjs'
  };

  // packages tells the System loader how to load when no filename and/or no extension
  var packages = {
    'app':                        { main: 'main.js',  defaultExtension: 'js' },
    'rxjs':                       { defaultExtension: 'js' },
    'angular2-in-memory-web-api': { main: 'index.js', defaultExtension: 'js' },
  };

  var ngPackageNames = [
    'common',
    'compiler',
    'core',
    'forms',
    'http',
    'platform-browser',
    'platform-browser-dynamic',
    'router',
    'router-deprecated',
    'upgrade'
  ];

  // Individual files (~300 requests):
  function packIndex(pkgName) {
    packages['@angular/'+pkgName] = { main: 'index.js', defaultExtension: 'js' };
  }

  // Bundled (~40 requests):
  function packUmd(pkgName) {
    packages['@angular/'+pkgName] = { main: '/bundles/' + pkgName + '.umd.js', defaultExtension: 'js' };
  }

  // Most environments should use UMD; some (Karma) need the individual index files
  var setPackageConfig = System.packageWithIndex ? packIndex : packUmd;

  // Add package entries for angular packages
  ngPackageNames.forEach(setPackageConfig);

  // No umd for router yet
  packages['@angular/router'] = { main: 'index.js', defaultExtension: 'js' };

  var config = {
    map: map,
    packages: packages
  };

  System.config(config);

})(this);

更新2

已将index.js文件添加到 systemjs.config.js 中的包中，并且根据屏幕截图

Update 2

Added the index.js file to the packages in systemjs.config.js and am receiving errors on the individual files as per screencap here:

systemjs.config.js(摘录)

 //packages tells the System loader how to load when no filename and/or no extension
  var packages = {
    'app':                        { main: 'main.js',  defaultExtension: 'js' },
    'rxjs':                       { defaultExtension: 'js' },
    'angular2-in-memory-web-api': { main: 'index.js', defaultExtension: 'js' },
    '@ng-bootstrap/ng-bootstrap': { main: 'index.js', defaultExtension: 'js' },
  };

推荐答案

找到了解决方案.问题确实出在 systemjs.config.js 上.按照说明进行操作，现在问题已解决.谢谢

Found a solution. Problem indeed lies in systemjs.config.js. Followed instructions and now the issue is fixed. Thanks
