angularjs - sass-loader の無効な CSS エラー

Question

私のapp.scss

.tes {
    color: red;
}

実行時の出力エラー./node_modules/.bin/webpack

ERROR in ./~/css-loader!./~/sass-loader?indentedSyntax!./www/assets/app.scss
Module build failed: 
.tes {
     ^
      Invalid CSS after ".tes {": expected "}", was "{"
      in ./www/assets/app.scss (line 1, column 7)
 @ ./www/assets/app.scss 4:14-135 13:2-17:4 13:2-17:4 14:20-141

じぶんのwebpack.config

 module: {
        loaders: [
            {
                test: /\.scss$/,
                loader: 'style!css!sass?indentedSyntax'
            },
            {
                test: /\.css$/,
                loader: 'style!css'
            }, {
                test: /\.(woff|woff2|ttf|eot|svg)(\?]?.*)?$/,
                loader: 'file-loader?name=res/[name].[ext]?[hash]'
            }
        ]
    },

と私app.js

require('./www/assets/app.scss');

var angular = require('angular');
var uiRouter = require('angular-ui-router');
require('velocity-animate');
require('node-lumx');

var HomeController = require('./www/components/home/homeController');

angular.module('app', ['lumx', uiRouter]) 
... //OMITED
