如何安全地将角材料添加到现有的角应用中？

Question

我正在尝试将Angular Material添加到我的应用程序中。我使用此npm命令

安装了Material组件

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

我必须将所有角度组件更新为7.0.2版本。 我添加了一个新的材料模块，并从我的app.module.js中引用了它

material.module.ts

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

import {
  MatButtonModule,
  MatMenuModule,
  MatToolbarModule,
  MatIconModule,
  MatCardModule
} from '@angular/material';

@NgModule({
  imports: [
    MatButtonModule,
    MatMenuModule,
    MatToolbarModule,
    MatIconModule,
    MatCardModule
  ],
  exports: [
    MatButtonModule,
    MatMenuModule,
    MatToolbarModule,
    MatIconModule,
    MatCardModule
  ]
})
export class MaterialModule {}

app.module.ts

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { HttpModule } from '@angular/http';
import { FormsModule } from '@angular/forms';

import { AppComponent } from "./app.component";
import { AppRoutingModule } from "./app-routing.module";

import { MaterialModule } from './material.module';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';



@NgModule({
    imports: [BrowserModule, AppRoutingModule, HttpModule, FormsModule, MaterialModule, BrowserAnimationsModule],
    declarations: [AppComponent],
    bootstrap: [AppComponent]

})
export class AppModule { }

这是我的package.json

  },
  "repository": {}
}

我清理了node_modules并重新安装了所有内容，以使我拥有所有最新文件。当我尝试构建项目时，会遇到各种错误。错误主要来自** \ @ angular \ core **或** \ @ angular \ common **

我花了太多时间，显然我错过了一些东西，因为它不应该那么复杂。

Answer 1

我可以看到两个潜在的问题：

1. 现在发布Angular Material 7需要RxJS 6.3。 您应该将RxJS软件包更新为"rxjs": "~6.3.3"。语法稍有变化，因此请查看此update guide。

2. 您是否已根据此step在主.scss文件中包含了基础材料主题文件？

此外，我认为您不是要安装"angular-material": "^1.1.10"软件包。它用于Angular.js。您可以删除它。

Answer 2

安装角材料

使用Angular CLI的安装示意图，通过运行以下命令来设置Angular Material项目：

ng添加@ angular / material

如果需要显示MatSliderModule

您需要通过将以下行添加到app.module.ts文件中来导入要显示的MatSliderModule。

从'@ angular / material / slider'导入{MatSliderModule};

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

像这样将标签添加到app.component.html中：

运行本地开发服务器：

ng服务 并将您的浏览器指向http://localhost:4200
