Webpack dev-server意外的标识符错误

我是React + Webpack的新手.作为教程的一部分,我编写了一个webpack.config.js文件.这是文件内容:

var webpack = require('webpack');
var path = require('path');

module.exports = {
    devtool: 'inline-source-map',
    entry: [
        'webpack-dev-server/client?http://localhost:8080/',
        'webpack/hot/only-dev-server',
        './src'
    ],
    output: {
        path: path.join(__dirname, 'public'),
        filename: 'bundle.js'
    },
    resolve:{
        moduleDirectories: ['node_modules', 'src'],
        extensions: ['', '.js']
    }
    module:{
        loaders:[
            {
                test: /\.jsx?$/,
                exclude: /node_modules/,
                loaders: ['react-hot','babel?presets[]=react,presets[]=es2015']
            }
        ]
    },
    plugins:[
        new webpack.HotModuleReplacementPlugin(),
        new webpack.NoErrorsPlugin()
    ]
};

我在第19->行遇到了意外的标识符错误 module:{...},

错误详情:

/home/adi/testcode/webpack.config.js:19
    module:{
    ^^^^^^
SyntaxError: Unexpected identifier
    at Object.exports.runInThisContext (vm.js:78:16)
    at Module._compile (module.js:543:28)

    at module.exports (/usr/lib/node_modules/webpack/bin/convert-argv.js:80:13)
    at Object. (/usr/lib/node_modules/webpack/bin/webpack.js:39:40)

我查了webpack.config.js一些例子,发现我写的是正确的.但它并没有按预期工作.不幸的是,我无法在GitHub问题,StackOverflow和Quora中找到解决方案.

我哪里弄错了？

你在模块属性之前忘了一个逗号
