Modul nicht gefunden: Fehler: Modul 'Server' kann nicht aufgelöst werden

Ich versuche, Webpack für die Verwaltung von Dateien in meinem Projekt zu verwenden. Ich verwende webpack-dev-server und bower-webpack-plugin. Wenn ich den Server starte, erhalte ich eine Fehlermeldung in der Browserkonsole.

Modul nicht gefunden: Fehler: Modul 'Server' kann nicht aufgelöst werden.

webpack.config.js

const BowerWebpackPlugin = require("bower-webpack-plugin");

module.exports = {
    entry: './src/script/index.jsx',
    output: {
        filename: 'bundle.js', //this is the default name, so you can skip it
        //at this directory our bundle file will be available
        //make sure port 8090 is used when launching webpack-dev-server
        publicPath: 'http://localhost:8090/assets'
    },
    devtool: 'source-map',
    module: {
        loaders: [
            {   
                test: /\.js[x]?$/, 
                loaders: ['react-hot', 'jsx', 'babel'],
                exclude: /node_modules/ 
              },
              {
                test: /\.scss$/,
                loaders: [ 'style', 'css?sourceMap', 'sass?sourceMap' ]
              }
        ]
    },
    plugins: [
        new BowerWebpackPlugin()
    ],
    externals: {
        //don't bundle the 'react' npm package with our bundle.js
        //but get it from a global 'React' variable
        'react': 'React'
    },
    resolve: {
        extensions: ['', '.js', '.jsx'],
        modulesDirectories: ["./src", "node_modules", "bower_components"]
    }
}

Edit: Jetzt verwende ich diese Webpack-Konfiguration ohne bower-webpack-plugin

Irgendwo in Ihren Quelldateien oder Bibliotheken von Drittanbietern gibt es eine Referenz auf eine Ressource mit dem Namen server (ohne Erweiterung). Es könnte in der Form von require('server') sein. Webpack versucht es am besten zu finden. Es prüft verschiedene Formen davon (z. B. server als Verzeichnis, server.js, server.jsx usw.) an verschiedenen Orten, schlägt jedoch am Ende fehl. Versuchen Sie herauszufinden, wo sich diese Referenz befindet.

Ähnliche Fehlermeldung, wenn versehentlich npm start server anstelle von npm run server verwendet wurde.

Wenn Sie server-Skript in Ihrem package.json haben, wird das Ausführen von npm run server gestartet. Wenn Sie npm start server verwenden, sucht es in Ihrer Quelle nach einem server-Modul und versucht, es zu starten.

Kleiner Tippfehler, kann jedoch aufgrund mangelnder Aufmerksamkeit leicht auftreten.

Ich habe einen ähnlichen Fehler beim webpack-dev-server erhalten. Obwohl Webpack global installiert wurde, musste ich es als Teil des Projekts installieren, um die Abhängigkeit von Webpack/Hot/Dev-Server aufzulösen

Meine Situation ist, dass ich TFS und Webpack verwendet habe und viele module not found-Fehler erhalten habe. 

Es stellte sich heraus, dass ich ein nicht vorhandenes Paket in meiner package.json-Datei hatte, das ich nicht gelöscht hatte.

"primeng": "1.0.0-rc.4",
"primeng-ultima": "Unavailable"

Sobald ich dieses Paket gelöscht habe, hat alles funktioniert.

Zum Glück führten mich die Protokolle zu dieser Schlussfolgerung. Was geschah, war, dass npm die Wiederherstellung der anderen Pakete übersprungen hatte, als dieses Paket nicht heruntergeladen werden konnte.
