angular - 如何在 angular2 中使用 angular2-material

Question

注意：我不使用 Angular Cli。

我添加了@angular2-material/core包。然后我安装了其他 angular2-material 组件，例如@angular2-material/button、@angular2-material/card等。

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',
    '@angular':                   'node_modules/@angular',
    'angular2-in-memory-web-api': 'node_modules/angular2-in-memory-web-api',
    'rxjs':                       'node_modules/rxjs',
    '@angular2-material':         'node_modules/@angular2-material', 
    // <--------------added this above line----------------------
  };
  // 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',
  ];

  //<------------------added this below part--------------------------------
var materialPackages=[
    'core',
    //'button',
    //'card',
    'list',
  ];
  materialPackages.forEach(function(pkgName) {
    packages['@angular2-material/'+pkgName] = { format: 'cjs', defaultExtension: 'js'};
  });
 //<----------------------till here---------------------------------


  // 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);
  var config = {
    map: map,
    packages: packages
  };
  System.config(config);
})(this);

当我运行我的应用程序时，我看到以下错误，

加载资源失败：服务器响应状态为 404（未找到） http://localhost:3000/node_modules/@angular2-material/sidenav/加载资源失败：服务器响应状态为 404（未找到） ) http://localhost:3000/node_modules/@angular2-material/toolbar/ 加载资源失败：服务器响应状态为 404 (Not Found) localhost/:16 Error: Error: XHR error (404 Not Found) loading http://localhost:3000/node_modules/@angular2-material/button (...)(匿名函数) @ localhost/:16 http://localhost:3000/node_modules/@angular2-material/card/加载资源失败：服务器响应状态为 404（未找到） http://localhost:3000/node_modules/@angular2-material/input/加载资源失败：服务器响应状态为 404（未找到） http://localhost:3000/node_modules/@angular2-material/checkbox /加载资源失败：服务器响应状态为 404（未找到）http://localhost:3000/node_modules/@angular2-material/radio/ 加载资源失败：服务器响应状态为 404（未找到找到） http://localhost:3000/node_modules/@angular2-material/icon/加载资源失败：服务器响应状态为404（未找到） http://localhost:3000/node_modules/@angular2-material /list/加载资源失败：服务器响应状态为 404（未找到） http://localhost:3000/favicon.ico加载资源失败：服务器响应状态为 404（未找到）

您应该在需要时单独添加材料组件system-config.ts：

1. angular-cli 定位`dist/`目录

const map: any = {
  '@angular2-material/core': 'vendor/@angular2-material/core'
};

const packages: any = {
  '@angular2-material/core': {
    format: 'cjs',
    defaultExtension: 'js',
    main: 'core.js'
  }
};

并在angular-cli-build.js：

vendorNpmFiles: [
  'systemjs/dist/system-polyfills.js',
  'systemjs/dist/system.src.js',
  'zone.js/dist/*.js',
  'es6-shim/es6-shim.js',
  'reflect-metadata/*.js',
  'rxjs/**/*.js',
  '@angular/**/*.js',
  '@angular2-material/**/*.js'
]

2. lite-server 或 http-server 定位应用程序根目录

const map: any = {
  '@angular2-material/core': 'node_modules/@angular2-material/core'
};

const packages: any = {
  '@angular2-material/core': {
    format: 'cjs',
    defaultExtension: 'js',
    main: 'core.js'
  }
};

这是system.config.ts来自角度材料2的来源：

材料2/GETTING_STARTED.md

npm

笨蛋

npm i @angular2-material/core --save

npm i @angular2-material/card --save

npm i @angular2-material/toolbar --save

npm i @angular2-material/button --save

npm i @angular2-material/slide-toggle --save

这适用于：Angular 2 QuickStart Source

零件：

import { MD_SLIDE_TOGGLE_DIRECTIVES } from '@angular2-material/slide-toggle';
import { MD_TOOLBAR_DIRECTIVES } from '@angular2-material/toolbar';

import { MD_CARD_DIRECTIVES } from '@angular2-material/card';
import { MD_BUTTON_DIRECTIVES } from '@angular2-material/button';
@Component({
    selector: 'my-app',
    directives: [MD_TOOLBAR_DIRECTIVES,MD_CARD_DIRECTIVES,MD_SLIDE_TOGGLE_DIRECTIVES, MD_BUTTON_DIRECTIVES],

    template: `

            <h1>
        {{title}}
        </h1>
        <md-toolbar color="primary">

        <div style="padding: 7px">
            <button md-button>Basic Button</button>

请将@angular2 RC4 更新为 RC5 并添加如下配置文件

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

  var ngVer = '@2.0.0-rc.5'; // lock in the angular package version; do not let it float to current!
  var routerVer = '@3.0.0-rc.1'; // lock router version
  var formsVer = '@0.3.0'; // lock forms version
  var routerDeprecatedVer = '@2.0.0-rc.2'; // temporarily until we update all the guides
