角材料2配置错误

Question

角度材料2使用cli.当我安装@ angular/material并将其包含在app.module中时,编译器会通过3个警告.

我做了什么

npm install --save @ angular/material

import { MaterialModule } from '@angular/material';

@NgModule({

  declarations: [
    AppComponent
  ],

  imports: [
    MaterialModule.forRoot(),other imports...
  ],

  providers: [],
  bootstrap: [AppComponent]
})

export class AppModule { }

其他设置

styles.css的

@import'~@angular/material/core/theming/prebuilt/deeppurple-amber.css';

的index.html

@import '~@angular/material/core/theming/prebuilt/deeppurple-amber.css';

警告

    <link href="https://fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet">

运行http:// localhost:4200 /时出错

Answer 1

从官方文档中，您应该导入每个模块。我在开发过程中一次性导入所有内容，但没有 .forRoot()，并且工作正常：

 imports: [
    MaterialModule,
  ],
