TypeError: Object(...) is not a function for angular-material

Question

In angular 7, trying to use angular material mat-dialog-content. While importing in app.module.ts it gives the following error:

TypeError: Object(...) is not a function like: Uncaught TypeError: Object(...) is not a function at platform.es5.js:102.

module.ts

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
import { ImageCropComponent } from './image-crop/image-crop.component';
import { MatDialogModule } from '@angular/material';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';


@NgModule({
  declarations: [
    AppComponent,
    ImageCropComponent
  ],
  imports: [
    BrowserModule,
    AppRoutingModule,
    MatDialogModule,
    BrowserAnimationsModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

Is there any dependency problem or something else?

    "@angular/animations": "^7.2.15",
    "@angular/cdk": "^8.0.1",
    "@angular/common": "~7.2.0",
    "@angular/compiler": "~7.2.0",
    "@angular/core": "~7.2.0",
    "@angular/forms": "~7.2.0",
    "@angular/material": "^8.0.1",
    "@angular/platform-browser": "~7.2.0",
    "@angular/platform-browser-dynamic": "~7.2.0",

You use @angular/cdk and @angular/material in version 8 together with @angular/core @angular/common 7. If you want to stay at Angular 7 uninstall cdk and material and install the specific cdk and material for version 7.

npm uninstall @angular/cdk @angular/material

... find out the version 7

npm show @angular/cdk versions
npm show @angular/material versions

... and then install the specific one

npm install @angular/[email protected]

Or just upgrade your angular

npm install -g @angular/cli@latest
ng update @angular/cli @angular-devkit/build-angular
ng update @angular/core @angular/cdk @angular/material

After one of this two options try it again.

replace npm install @angular/[email protected] to npm install @angular/[email protected] and it worked for me.

Change the dependencies to the lowest version of @angular/core or @angular/cdk. It's normally due to a mismatch

"dependencies": {
  "@angular/core": "^7.2.0",
  "@angular/cdk": "^7.2.0",
  "@angular/material": "^7.2.0"    
},
