can not set locale with webpack

Hi, guys, I really need some help. I'm using angular 1.6, webpack and es6, I import moment and locale file , and did the configure as document said. but still can not set the locale lang. Here's my code:

webpack.config.js:

process.env.NODE_ENV == 'production';
var debug = process.env.NODE_ENV !== 'production';
var webpack = require('webpack');
var path = require('path');

module.exports = {
    context: path.join(__dirname, 'src'),
    devtool: debug ? 'inline-sourcemap' : null,
    //devtool: null,
    entry: {
        app: [ './js/app.js' ],
        vendor: [ 'angular' ]
    },
    module: {
        loaders: [
            {
                test: /\.js$/,
                exclude: /node_modules/,
                loader: 'babel-loader',
                query: {
                    presets: ['es2015']
                }
            }
        ]
    },
    watch: true,
    output: {
        path: __dirname + '/src',
        filename: 'main.js'
    },
    plugins: [
        new webpack.optimize.CommonsChunkPlugin({
            names: "vendor",
            filename: "vendor.js",
            minChunks: Infinity
        })
    ]
};

<script src="vendor.js"></script>
<script src="main.js"></script>
</body>
</html>

app.js:

import angular from 'angular';
import moment from 'moment';
import 'moment/locale/zh-cn';

moment.locale('zh-cn');

require('imports?this=>window,exports=>false,define=>false!angular-datepicker');

angular.module('adwApp', ['datePicker'])
