Angular 不显示角度材质组件

我不熟悉Angular 2和Angular Material，我尝试创建一个示例来检查Angular Material，但它不起作用。我得到一个空的html页面。我的代码如下

应用程序组件ts:

import { Component } from '@angular/core';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  title = 'app';
}

应用程序模块.ts

    import { BrowserModule } from '@angular/platform-browser';
    import { NgModule } from '@angular/core';
    import { AppComponent } from './app.component';
    import {MdSidenavModule,MdMenuModule} from '@angular/material';
    import {BrowserAnimationsModule} from '@angular/platform-browser/animations'; 
    import {NoopAnimationsModule} from '@angular/platform-browser/animations';
    import 'hammerjs';

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    MdSidenavModule,
    BrowserAnimationsModule,
    NoopAnimationsModule,
    MdMenuModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})


export class AppModule { }

App组件Html

我已经包括了所有的依赖项，如在网上提到的。请帮我解决这个问题

我认为问题并不特别在于您的代码。从您的评论中，我发现您的一个项目依赖项有问题（

@angular/platform browser

）。angular中报告的有一个bug：

尝试将依赖项更新为最新的：

4.2.6

为此，需要运行以下命令：

 npm update

要确保您是最新的，请检查已安装软件包的版本：

npm ls --depth 0

如果已经通过

MaterialModule

导入了所有组件，则也不需要单独导入每个组件

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

---

从“@angular/material”中删除

import{MaterialModule}和
MaterialModule
从
导入：[]
。自从
beta.3版以来，它就被弃用了

另外，添加
NoopAnimationsModule

import {NoopAnimationsModule} from '@angular/platform-browser/animations';

@NgModule({
  ...
  imports: [NoopAnimationsModule],
  ...
})

我还发现您的错误列在Github中。现在的解决方案似乎是退回到
动画
版本
4.1.3

尝试
npm安装'@angular/animations'@4.1.3'--保存

如果有帮助，请告诉我

更新：

import { Component } from '@angular/core';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  title = 'app';
}

md menu
未显示，因为它需要一个可以打开菜单的
mdMenuTriggerFor
。在此之前，它一直处于隐藏状态。此外，要使
sidenav
正常工作，所有内容都需要在
md sidenav容器
标记内

请使用以下内容更改您的html代码：

<md-sidenav-container style="height: 500px">

  <button md-icon-button [mdMenuTriggerFor]="menu">
    <md-icon>more_vert</md-icon>Menu
  </button>


  <md-sidenav opened="true" #sidenav 
      style="background-color: skyblue">
    <button md-raised-button style="margin: 2px 0 0 6px">
     Add
    </button>
    <p>This is Sidenav</p>
   </md-sidenav>

   <md-menu #menu="mdMenu">
     <button md-menu-item (click)="sidenav.open()"> Sidenav </button>
    <button md-menu-item> Settings </button>
    <button md-menu-item> Help </button>
  </md-menu>

</md-sidenav-container>


更多菜单
添加
这是Sidenav

侧导航

帮助

我也有同样的问题。我发现styles.scss中没有主题。我添加了一个预构建的主题和渲染的组件。
你为什么要注释掉BrowserAnimationsModule？你有没有遇到任何与之相关的问题？是的，我在/media/sarang/Data/anguler2/ngmaterial/node_modules/@angular/platform browser中遇到以下错误/animations/src/providers.d.ts（8119）：Module'/media/sarang/Data/anguler2/ngmaterial/node_modules/@angulation/animations/browser''没有导出成员“ɵdomaniationengine”。另外，我在../~/@angular/compiler/@angular/compiler.es5.js中收到一条警告（发出的值而不是错误实例）找不到源文件“compiler.es5.ts”：错误：无法在“/media/sarang/Data/anguler2/node_modules/@angular/compiler/@angular'@..//@angular/platform-browser-dynamic/@angular/platform-browser-dynamic.es5.js 11:0-72@./src/main.ts@multi-webpack dev server/client？/src/main.这是问题的根源吗？还是我们可以忽略nore warning你能把你的
包.json
放在问题中吗？当然我会在我的问题中添加它。期待结果：）我更新了我的依赖项，错误和警告都消失了。但得到空白HTML页面仍然是同一个问题：-（@SarangShinde您是否取消了代码行的注释？另外，由于您已经导入了
MaterialModule
，因此不必导入模块（e.x.
MdMenuModule
）再次单独。@SarangShinde对于
md按钮
，将
md按钮
属性添加到
按钮
。console Maciej中没有错误，是的，Edric为相同的按钮添加了md按钮和导入的MdButtonModule。但仍然存在问题：-（.是的，Nehal我尝试了你告诉我的内容，也更新了我的app.modules.ts文件，但问题仍然存在于空白HTML文件中。我是否在配置或代码中丢失了一些内容？.在HTML文件中编写一些简单的内容，如Hello，然后查看是否显示出来？是的，它显示了除角度材质标记以外的所有内容。发现了问题。我将您的代码放入了一个plunker中d没有显示任何内容。原因是
md菜单
需要一个触发器。因此，您必须添加一个
按钮
，您可以单击该按钮来触发菜单。此外，如果您查看sidenav的物料文档，则所有内容都需要在
md sidenav容器
中。请参阅我的更新答案。希望这能解决您的问题。是的，是这样的我解决了我的问题，现在工作正常。谢谢你的宝贵努力。
