Error Cannot find module '@angular/material

Error

Cannot find module '@angular/material

app.module.ts

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

Link :https://material.angular.io/guide/getting-started

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

The solution that I tried

npm update

it doesn't works.

ng --version

@angular/cli: 1.2.1
node: 8.3.0
os: win32 x64
@angular/animation: 4.0.0-beta.8
@angular/animations: error
@angular/cdk: error
@angular/common: 4.3.2
@angular/compiler: 4.3.2
@angular/core: 4.3.2
@angular/forms: 4.3.2
@angular/http: 4.3.2
@angular/material: error
@angular/platform-browser: 4.3.2
@angular/platform-browser-dynamic: 4.3.2
@angular/router: 4.3.2
@angular/cli: 1.2.1
@angular/compiler-cli: 4.4.3
@angular/language-service: 4.3.2

I have made working demo https://github.com/afeef1915/Angular2-Symfony3-Demo

where all code was working fine.

Look at the error and you will see that some packages need angular v.4.4.4. So I recommend you to update all @angular-packages to v.4.4.4.

Follow this steps:

1.) remove node_modules

2.) npm cache clean

3.) open packages.json and set the version by all @angular-packages to "^4.4.4"

4.) npm install

Here the changelog of material 2:

its says: Angular Material now requires Angular 4.4.3 or greater since 2.beta-11

If you want the last version of material you have to upgrade to angular 5+

If you want to stick to version 4.3.2 the last you can install is 2.0.0-beta10 ( i don't recommend that )
