unable to locate package "@angular/material"

Question

unable to locate package "@angular/material"

Having an issue with Angular 2 as I try to import "@angular/material". The error occurs when importing packages like:

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

Here is my tsconfig.json file:

{
 "compilerOptions": {
"baseUrl": "",
"declaration": false,
"emitDecoratorMetadata": true,
"experimentalDecorators": true,
"lib": ["es6", "dom"],
"mapRoot": "./",

}
}

Answer №1

Here are the steps to get started with Angular Material:

Step 1: Installing Angular Material

npm install --save @angular/material

Step 2: Adding Animations

Certain Material components require the Angular animations module for advanced transitions. To enable these animations, install the @angular/animations module and import BrowserAnimationsModule into your app:

npm install --save @angular/animations

Then add this code snippet to your app:

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

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

Step 3: Importing Component Modules

Import the NgModule for each component you wish to use:

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

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

Remember to import Angular Material modules after BrowserModule in your imports list.

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 { }

Step 4: Applying a Theme

To style your application with core and theme styles, including a theme is necessary.

For a quick start with a prebuilt theme, insert the following line in your index.html file:

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

Answer №5

Despite following all the advice given (I'm currently working with Angular 7), none of it seemed to solve my problem. My application simply refused to recognize the existence of @angular/material, leading to an error being displayed on this particular line:

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

Even though I was utilizing the --save flag when attempting to incorporate Angular Material into my project:

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

...it stubbornly declined to make any additions to my "package.json" file.

I even went as far as deleting the package-lock.json file, a suggestion made in various articles as a potential fix, but unfortunately, this did not yield any results.

To resolve this issue, I found myself having to manually insert these two lines into my "package.json" file.

{
    "devDependencies": {
        ...
        "@angular/material": "~7.2.2",
        "@angular/cdk": "~7.2.2",
        ...

The puzzling part for me is whether this problem stems from using Angular 7 specifically or if it's something that has persisted over several years...

Just stumbled upon a helpful post about the "Breaking changes" in Angular 9. It looks like all modules now must be imported separately. I also found a great module shared by @jeff-gilliland worth checking out:

None of the solutions provided seemed to fix my issue. Drawing from past experiences where node modules have caused problems while working with ReactJS, I decided to take a different approach. I removed my node_modules folder and reinstalled it using 'npm install'. Instead of using

import { MatTableModule } from '@angular/material'

, I opted to import the module as

import { MatTableModule } from '@angular/material/table'

. Surprisingly, this change resolved the issue for me :-).
