javascript - 如何修复 Angular Material Components 的构建错误？

Question

我是否在配置中遗漏了什么？

ng 版本命令

Node: 8.1.1
OS: win32 x64
Angular: 5.2.5
... common, compiler, compiler-cli, core, forms, http
... language-service, platform-browser, platform-browser-dynamic
... router

@angular/animations: 5.2.9
@angular/cdk: 5.2.4
@angular/cli: 1.7.0
@angular/material: 5.2.4
@angular-devkit/build-optimizer: 0.3.1

重现步骤

第 1 步创建新项目 ng new any-name第 2 步 按照 https://material.angular.io/guide/getting-started 上的步骤操作即

npm install --save @angular/material @angular/cdk
npm install --save @angular/animations

步骤 3

Material.module.ts

import {MatButtonModule,
        MatCheckboxModule} from '@angular/material';
 @NgModule({
   imports: [MatButtonModule, MatCheckboxModule],
 })
 export class MaterialModule { }

app.component.html

<div>
  <input type="button" mat-button placeholder="Holla!">

  <button mat-raised-button >Click me!</button>
  <mat-checkbox>Check me!</mat-checkbox>
</div>

应用程序模块.ts

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

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

import { AppComponent } from './app.component';
import {MaterialModule} from '../shared/material.module'

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

样式.css

/* You can add global styles to this file, and also import other style files */
@import "~@angular/material/prebuilt-themes/indigo-pink.css";

观察到的行为

compiler.js:485 未捕获错误:模板解析错误:'mat-checkbox' 不是已知元素:

1. 如果“mat-checkbox”是一个 Angular 组件，则验证它是该模块的一部分。

2. 如果“mat-checkbox”是一个 Web 组件，则将“CUSTOM_ELEMENTS_SCHEMA”添加到此组件的“@NgModule.schemas”以禁止显示此消息。 ("

期望的行为

希望看到什么实现？它应该加载 Angular Material 组件。

主要.ts

import { enableProdMode } from '@angular/core';
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import 'hammerjs';
import { AppModule } from './app/app.module';
import { environment } from './environments/environment';

if (environment.production) {
  enableProdMode();
}

platformBrowserDynamic().bootstrapModule(AppModule)
  .catch(err => console.log(err));

Answer 1

@import "~@angular/material/prebuilt-themes/indigo-pink.css";
在 style.css 中添加这个
