角材料2不工作在角2.0.0应用程序

Question

我有一个应用程序可以加载Angular 2.0。0，所有rc版本之后的9/14/16版本。我试图添加AngularMaterial2，谷歌团队发布的官方MD版本。我正在从他们的入门网站复制/粘贴代码，但我使用的是Atom而不是angular cli，因为我已经构建了应用程序的开始部分。Atom typescript找到了所有内容，并表示没有错误。但是，尽管经过了大量的试用，当修改后的应用程序无法加载时，我还是会反复出现这些找不到的控制台错误。

zone.js:1263GEThttp://localhost:3000/node_modules/@angular2-材质/按钮/404（未找到）安排任务@zone.js:1263

主页：27错误：（SystemJS）XHR错误（404未找到）加载http://localhost:3000/node_modules/@角度2材质/按钮（…）

区js:1263获取http://localhost:3000/node_modules/@angular2材料/清单/404（未找到）

我已经查看了上面的node_模块文件，它们存在于我的代码中。

根据入门说明，相关代码为：

应用程序。单元ts

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

systemjs。配置。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列表、md列表项和md按钮标记。

我应该换什么？

Answer 1

随着Angular材质2版本2.0.0-alpha.9的中断更改，您可以简单地将这一行映射为systemjs.config.ts

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

package.json也变得更简单：

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

别忘了导入NGM模块

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

从物质2发布：

角度材质已从@angular2 Material/…更改为。。。包装到@angular/material下的单个包装。除此之外，还有一个新的模块MaterialModule，它包含所有组件。。。

今天早上（9/16），我用Angular2（决赛），Angular2材料2.0让它开始工作。0-α。8-2和TypeScript 2.0。0.正如您在包中看到的。在下面的json中，我按照本视频中的说明安装（并运行）了大多数当前可用的Angular2材质组件。

发布我的系统。配置。这样您就可以看到它，希望它能帮助您排除故障。

将typescript更新为2.0版。0

还必须为hammerjs（触摸手势支持）注册打字，但我相信只有在使用MdIconMoules时，您才需要这样做。
