Angular – Upgrading to angular 9 – @angular/flex-layout peer dependency to @angular/cdk

angularangular-material

I encountered following the error whilst updating from angular 8 to 9 and running

ng update @angular/material:

Package "@angular/flex-layout" has an incompatible peer dependency to "@angular/cdk" (requires "^8.0.0-rc.0", would install "9.0.0").

You have to update both dependencies at the same time. Had the same issue when only updating one at a time.

ng update @angular/material @angular/flex-layout

Hope this helps.

To resolve this problem HttpClient is Angular's mechanism for communicating with a remote server over HTTP.

To make HttpClient available everywhere in the app,

open the root AppModule,
import the HttpClientModule from @angular/common/http,

import { HttpClientModule } from '@angular/common/http';
add it to the @NgModule.imports array.

imports:[HttpClientModule, ]

Install @angular-devkit/build-angular as dev dependency. This package is newly introduced in Angular 6.0

npm install --save-dev @angular-devkit/build-angular

or,

yarn add @angular-devkit/build-angular --dev
