The error
./node_modules/bootstrap/dist/css/bootstrap.css:8:0 - Error: Module parse failed: Unexpected token (8:0)
You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders

The question
I keep getting this error when I try to import bootstrap.css. Some solutions I have looked at involve adding a css loader in webpack.config.js but as I have installed my app using angular-cli, I'm unable to see it.

I'm importing bootstrap like this:
import { Component} from '@angular/core';
import '../../node_modules/bootstrap/dist/css/bootstrap.css';
import '../styles.css';
import { Inject, enableProdMode, NgModule } from '@angular/core';
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { BrowserModule } from '@angular/platform-browser';
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css', '../styles.css']
})
export class AppComponent {
...
}
Attempted Solutions
- Tried installing other version of bootstrap, same error
- Currently trying custom-webpack builder, but not sure if that will work.
CodePudding user response：
In Angular application, you should not load CSS files like you mentioned in AppComponent File.
You have correctly added bootstrap files in angular.json and this will be suffice to include it in the angular project.
Please remove the import from Appcomponent file and try to build it. I have built several angular applications without any issues ( created via Angular CLI ).
Please let us know the outcome.
