Not able to import "@angular/material" module

Question

I'm totally new to mean stack and I'm facing some problems with Angular's material module. I'm trying to import the "@angular/material" module in my code but I'm getting an error whenever I'm importing it. The error is as follows:

ERROR in src/app/app.module.ts:5:32 - error TS2306: File '/Users/anmolsarraf/Desktop/MEAN Stack/mean-course/node_modules/@angular/material/index
.d.ts' is not a module.

Here is my package.json file:

   {
  "name": "mean-course",
  "version": "0.0.0",
  "scripts": {
    "ng": "ng",
    "start": "ng serve",

    "e2e": "ng e2e"
  },

    "ts-node": "~7.0.0",
    "tslint": "~5.15.0",
    "typescript": "~3.5.3"
  }
}

Here is my app.module.ts file:

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { MatInputModule } from '@angular/material/input';

import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
import { PostCreateComponent } from './posts/post-create/post-create.component';

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

To be exact I'm trying to do import { MatInputModule } from '@angular/material'; and I'm getting the above-mentioned error.

I have tried importing the above module as import { MatInputModule } from '@angular/material/input'; but then it throws a bunch of error saying node_modules/@angular/material/input/input.d.ts:138:9 - error TS1086: An accessor cannot be declared in an ambient context.

Any help would be highly appreciated. Thanks!

UPDATE

I created a new instance of an Angular app and then tried to import angular material in it, somehow it worked since I'm not getting any errors while importing it. Thanks!

You need to be more specific:

import {MatInputModule} from '@angular/material/input';

not just

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

and then add it to your imports
