找不到模块"@ angular/material"

Question

我正在使用Angular 2.当我尝试导入"@ angular/material"时,我收到了错误.我正在导入类似的包:

import {MdDialog} from "@angular/material";
import {MdDialogRef} from "@angular/material";

我的tsconfig.json文件如:

{
 "compilerOptions": {
"baseUrl": "",
"declaration": false,
"emitDecoratorMetadata": true,
"experimentalDecorators": true,
"lib": ["es6", "dom"],
"mapRoot": "./",
"module": "es6",
"moduleResolution": "node",
"outDir": "../dist/out-tsc",
"sourceMap": true,
"target": "es5",
"typeRoots": [
  "../node_modules/@types"
]
}
}

我的package.json代码:

{
 "name": "rmc-temporary",
 "version": "0.0.0",
 "license": "MIT",
 "angular-cli": {},
 "scripts": {
   "start": "ng serve",

Answer 1

请按照以下步骤开始使用Angular Material.

第1步:安装角度材质

npm install --save @angular/material

第2步:动画

某些Material组件依赖于Angular动画模块,以便能够执行更高级的过渡.如果您希望这些动画在您的应用中运行,则必须安装该@angular/animations模块并在您的应用中包含BrowserAnimationsModule.

npm install --save @angular/animations

然后

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

@NgModule({
...
  imports: [BrowserAnimationsModule],
...
})
export class PizzaPartyAppModule { }

第3步:导入组件模块

为要使用的每个组件导入NgModule:

import {MdButtonModule, MdCheckboxModule} from '@angular/material';

@NgModule({
...
imports: [MdButtonModule, MdCheckboxModule],
...
 })
 export class PizzaPartyAppModule { }

一定要在Angular的BrowserModule之后导入Angular Material模块,因为导入顺序对NgModules很重要

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

import {MdCardModule} from '@angular/material';
@NgModule({
    declarations: [
        AppComponent,
        HeaderComponent,
        HomeComponent
    ],
    imports: [
        BrowserModule,
        FormsModule,
        HttpModule,
        MdCardModule
    ],
    providers: [],
    bootstrap: [AppComponent]
})
export class AppModule { }

第4步:包含主题

包含主题是将所有核心和主题样式应用于您的应用程序所必需的.

要开始使用预建主题,请在应用的index.html中包含以下内容:

<link href="../node_modules/@angular/material/prebuilt-themes/indigo-pink.css" rel="stylesheet">

Answer 2

那就是为我解决这个问题的原因。

我用了：

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

但在应用程序的文件夹中。

Answer 3

• 步骤1：npm install @angular/material
• 第2步：import {MatDialogModule} from "@angular/material/dialog";
• 第3步：导入应用程序模块后：

    @NgModule({
      imports: [
        CommonModule,
        MatDialogModule
       ]

• 第4步：导入组件： import { MatDialog} from '@angular/material/dialog';

• 第5步：使用弹出对话框

    showPopup(Id){
            this.matDialog.open(PopupComponent, {
                disableClose: true,
                width: "1200px",
                data: {
                  Title: "im vuong le - dev VietNam",
                  sepId:Id,
                  Message: "test-dialog,
                },
              })
                .afterClosed()
                .subscribe((result) => {
                  if (result == "Yes") {
                    
                  }
                });
        }
