Error Adding Angular Material to Existing Angular 7 App

I am attempting to add Angular Material to my existing Angular 7 app so that I can use the MatDialogModule. I keep getting the following error:

WARNING in ./node_modules/@angular/cdk/esm5/a11y.es5.js 2324:55-73 export 'ɵɵdefineInjectable' was not found in '@angular/core'

Below are the relevant portions of my app.module.ts and package.json

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule, ReactiveFormsModule } from '@angular/forms';
import {BrowserAnimationsModule} from '@angular/platform-browser/animations';
import { MatDialogModule } from '@angular/material/dialog';

 ...

@NgModule({

  imports: [
    BrowserModule,
    FormsModule,
    ReactiveFormsModule,
    AppRoutingModule,
    [BrowserAnimationsModule],
    MatDialogModule,
  ],

"@angular/cdk": "^8.0.0", should be changed to you angular version. By default it install latest version.

If you're upgrading your site, be sure to update all your dependencies via ng update, and if your problem remains, you may need to remove your node_modules folder and reinstall them with npm install to be sure that there are no problems with them.
Happy coding!

I had the exact same problem when you run

npm install

you should see some warnings saying you need to install another package for angular material to work. In my case I had to run

npm i @angular/core@^8.0.0

Hope this helps.

I had this same issue, and it was that i was using @angular/[email protected] and @angular/[email protected] and @angular/[email protected].

I know you mentioned downgrading material and cdk, but maybe your core version was mismatched. by making sure all 3 were ~7.2.0, and properly importing material after the browsermodule, i was able to get the app to run.
