I have created a new project but whenever I am compiling getting the 2 below error messages:

Error: Module not found: Error: Can't resolve 'C:/Users/Avishek/Documents/practice/frontend/src/app/pages/admin/authentication/authentication.component.css' in 'C:\Users\Avishek\Documents\practice\frontend'

and

Error: The loader "C:/Users/Avishek/Documents/practice/frontend/src/app/pages/admin/authentication/authentication.component.css" didn't return a string.

I have never faced this type of issue before even few days back I created a project with the same angular version still did not get. Below is my tsconfig.json & package.json files respectively.

The problem in my case was that my project was configured to use scss files but that I had copied some code from a sample that used css files. So in one of my components I had:

@Component({
   selector: 'app-root',
   templateUrl: './app.component.html',
   styleUrls: ['./app.component.css']
})

The css file in the stypeUrls property was the cause of the error.

Just misspelling your styleUrls

use scss instead of css

If your using SCSS in your project change your styleUrls from:

@Component({
  selector: 'app-hero-detail',
  templateUrl: './hero-detail.component.html',
  styleUrls: [ './hero-detail.component.css' ] //Notice
})

To:

@Component({
  selector: 'app-hero-detail',
  templateUrl: './hero-detail.component.html',
  styleUrls: [ './hero-detail.component.scss' ] //Notice
})

That worked for my project

For Me I already dont have scss or CSS file in my folder so I just remooved the line styleUrls: [ './hero-detail.component.scss' ]

It worked for me.

i solved this problem by checking the path pricesily because i was working on projects and there were many files , so my path was needing an additional /.. /
