Angular 2 - Module not found: Error: Can't resolve '@angular/material'

Question

I followed each steps described here: https://material.angular.io/guide/getting-started

Error I get

ERROR in ./src/app/app.module.ts
Module not found: Error: Can't resolve '@angular/material' in '/Users/isabelle/my-project/src/app'
@ ./src/app/app.module.ts 14:0-51
@ ./src/main.ts
@ multi webpack-dev-server/client?http://localhost:4200/ ./src/main.ts

What I did

npm install -g @angular/cli
ng new my-project
npm install --save @angular/material

In src/app/app.module.ts

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

Answer 9

I had this same issue, I was building the project from the scratch. For me what I did wrong is I was trying to run

ng add @angular/material

Before running the

npm install

Command

Once I ran the "npm install" first and then tried to install materials, everything started to install properly without any issues. Its a very silly basic mistake which is worth to note for beginers like me :)

Delete Your node_modules folder and package.lock.json file manually and then npm install if not work then ng add@angular/material
