Webpack build step isn't generating build files

Question

When I run npm build nothing seems to happen. When I look for the build files I don't see anything. npm start works fine though.

Package.json

  "name": "pro-react-webpack",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "start": "webpack-dev-server --progress",

    "test": "echo \"Error: no test specified\" && exit 1"
  },

  },

  }
}

Webpack.production.config.js

var webpack = require('webpack');
var HtmlWebpackPlugin = require('html-webpack-plugin');
var ExtractTextPlugin = require('extract-text-webpack-plugin');

module.exports = {
    entry: __dirname + "/app/main.js",
    output: {
        path: __dirname + "/build",
        filename: "bundle.js"
    },

    module: {
        loaders: [
            {
                test: /\.json$/,
                loader: "json"
            },
            {
                test: /\.js$/,
                exclude: /node_modules/,
                loader: 'babel'
            },
            {
                test: /\.css$/,
                loader: ExtractTextPlugin.extract('style', 'css?modules!postcss')
            }
        ]
    },
    postcss: [
        require('autoprefixer')
    ],

    plugins: [
        new HtmlWebpackPlugin({
            template: __dirname + "/app/index.tmpl.html"
        }),
        new webpack.optimize.OccurenceOrderPlugin(),
        new webpack.optimize.UglifyJsPlugin(),
        new ExtractTextPlugin("style.css")
    ]
}

I also have .babelrc file and webpack.config.js file, let me know if those would be useful to see as well, thanks.

Might be related to the fact that build is an internal command. Seems like I have had this happen to me as well in the past. Check out this Question

In order to run a custom script, you can use the npm run-script build or just npm run build. As stated in the NPM documentation
