角material2在角2.0.0应用程序中不起作用

Question

我有一个应用程序，加载角2.0.0，9/14/16发布后，所有的rc版本。我试图添加角Material2，官方发布的MD从谷歌团队。我是复制/粘贴代码，从他们的入门网站，但我使用的是Atom，而不是角-cli，因为我已经建立了应用程序的开始。原子类型记录找到了所有的东西，并说没有错误。但是，尽管经历了大量的尝试，但当修改后的应用程序无法加载时，我反复地发现了这些没有找到的控制台错误。

zone.js:1263 GET 模块/@angular2-材料/按钮/ 404 (未找到)scheduleTask@ zone.js:1263

主页:27错误：(SystemJS) XHR错误(404未找到)加载模块/@angular2-材料/按钮(…)

zone.js:1263 GET 模块/@angular2-资料/清单/ 404 (未找到)

我查看了上面的node_modules文件，它们存在于我的代码中。

根据入门指南，相关代码是：

app.module.ts

import { MdButtonModule } from '@angular2-material/button';
import { MdListModule } from '@angular2-material/list';
@NgModule({
  imports:      [ BrowserModule,
                  FormsModule,
                  MdButtonModule,
                  MdListModule,
                  routing
  ],

systemjs.config.js

var map = {
'@angular2-material':                   'node_modules/@angular2-material',
'@angular2-material/core':                   'node_modules/@angular2-material/core/core',
'@angular2-material/list':                   'node_modules/@angular2-material/list',
'@angular2-material/button':                   'node_modules/@angular2-material/button'
};
var packages = {
'app':                        { main: 'main.js',  defaultExtension: 'js' },
'rxjs':                       { defaultExtension: 'js' },
'angular2-in-memory-web-api': { main: 'index.js', defaultExtension: 'js' },
};
function packIndex(pkgName) {
packages['@angular/'+pkgName] = { main: 'index.js', defaultExtension: 'js' };
}
function packUmd(pkgName) {
packages['@angular/'+pkgName] = { main: 'bundles/' + pkgName + '.umd.js', defaultExtension: 'js' };
}
var setPackageConfig = System.packageWithIndex ? packIndex : packUmd;
ngPackageNames.forEach(setPackageConfig);

HTML页面有两个md-list、md-list-item和md-按钮标签.

我该换什么？

从9/16开始，我就可以使用Angular2 (final)、Angular2-Material2.0.0-字母-8-2和TypeScript 2.0.0使用它了。正如您在下面的package.json中所看到的，我已经按照这段视频的说明安装(并运行)了大多数当前可用的Angular2材料组件。

发布我的system.config.ts，这样你就可以看到它，希望它能帮助你解决疑难问题。

/**

 * 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

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

我的package.json的相关部分：

      ...   
      "dependencies": {
        "@angular/common": "~2.0.0",
        "@angular/compiler": "~2.0.0",

        "core-js": "^2.4.1",
        "hammerjs": "^2.0.8",
        "reflect-metadata": "^0.1.3",
        "rxjs": "~5.0.0-beta.12",
        "systemjs": "~0.19.27",
        "zone.js": "^0.6.21"
      },
      "devDependencies": {
        "concurrently": "^2.2.0",
        "lite-server": "^2.2.2",
        "typescript": "^2.0.0",
        "typings": "^1.3.2"
      }
      ...

更新的类型记录到2.0.0版。

此外，还必须注册锤子的类型(触摸手势支持)，但我相信只有在使用MdIconModule时才需要这样做。

随着角材料2版本2.0.0-字母9的突然变化，您可以简单地在systemjs.config.ts中映射这一行

'@angular/material': 'npm:@angular/material/material.umd.js',

package.json也变得更简单，因为：

"@angular/material": "^2.0.0-alpha.9-3"

别忘了导入NgModule

import { MaterialModule } from '@angular/material';
@NgModule({
  ...
  imports: [MaterialModule.forRoot()],
  ...
})

来自material2释放

角材料已从@angular2-材料/.包装到一个包下面的@角/材料。除了这一变化之外，还有一个新的NgModule，MaterialModule，它包含所有组件。..。
