I just created a new project with `yo aspnetcore-spa`. I'm trying to use the [PrimeNG](https://www.primefaces.org/primeng/#/) component library.
Then I installed font-awesome and primeng:

```
npm install font-awesome primeng --save

```

Then added CSS to the webpack vendor list:

```
 vendor: [
    '@angular/common',
    '@angular/compiler',
    '@angular/core',
    '@angular/http',
    '@angular/platform-browser',
    '@angular/platform-browser-dynamic',
    '@angular/router',
    '@angular/platform-server',
    'angular2-universal',
    'angular2-universal-polyfills',
    'bootstrap',
    'bootstrap/dist/css/bootstrap.css',
    'es6-shim',
    'es6-promise',
    'event-source-polyfill',
    'jquery',
    'zone.js',
    'font-awesome/css/font-awesome.min.css',
    'primeng/resources/primeng.min.css',
    'primeng/resources/themes/omega/theme.css'
]

```

Then when I try to update the vendor files:

```
node node_modules/webpack/bin/webpack.js --config webpack.config.vendor.js

```

I get this errors:

```

Any idea what should I do to have no error with webpack?

**EDIT** 

As asked, here are my webpack config:

* [webpack.config.js](https://github.com/jgrossrieder/Astro/blob/master/Clients/Astro.Clients.Web2/webpack.config.js)
* [webpack.config.vendor.js](https://github.com/jgrossrieder/Astro/blob/master/Clients/Astro.Clients.Web2/webpack.config.vendor.js)
