sass - Webpack: cannot resolve module 'file-loader'

Question

When I try to build SASS file with webpack, I got the following error:

Module not found: Error:Cannot resolve module 'file-loader'

note that this issue only happen when i try to load background image using relative path.

this Work fine:

  background:url(http://localhost:8080/images/magnifier.png);

this cause the issue:

   background:url(../images/magnifier.png);

and this is my project structure

• images
• styles
• webpack.config.js

and this is my webpack file:

var path = require('path');
module.exports = {
    entry: {
        build: [
            './scripts/app.jsx',
            'webpack-dev-server/client?http://localhost:8080',
            'webpack/hot/only-dev-server'
        ]
    },
    output: {
        path: path.join(__dirname, 'public'),
        publicPath: 'http://localhost:8080/',
        filename: 'public/[name].js'
    },
    module: {
        loaders: [
            {test: /.jsx?$/, loaders: ['react-hot', 'babel?stage=0'], exclude: /node_modules/},
            {test: /.scss$/, loaders: ['style', 'css', 'sass']},
            {test: /.(png|jpg)$/, loader: 'file-loader'},
            {test: /.(ttf|eot|svg|woff(2)?)(?[a-z0-9]+)?$/, loader: 'file-loader'}
        ]
    },
    resolve: {
        extensions: ['', '.js', '.jsx', '.scss', '.eot', '.ttf', '.svg', '.woff'],
        modulesDirectories: ['node_modules', 'scripts', 'images', 'fonts']
    }
};

As @silvenon said in his comment:

Do you have file-loader installed?

yes file-loader was installed but broken, and my issue has been solved by re-installing it.

npm install --save-dev file-loader
