这是我的配置

var webpack          = require('webpack');
var webpackDevServer = require('webpack-dev-server');
var wecpackConfig    = module.exports = {};//　init object

// input
wecpackConfig.entry　 =　{
  app:[
    './app.js',

    './bower_components/ratchet/dist/css/ratchet.css',
    './bower_components/font-awesome/css/font-awesome.css'
  ],
};

wecpackConfig.output = {
  path:'./dist',
  filename: '[name].js'
};//　output

//doc loader
wecpackConfig.module = {
  loaders : [
    { 
      test: /\.css$/, 
      loader: 'style!css'
    },
    { 
      test: /\.vue$/, 
      loader: 'vue'
    },
    { test: /\.js$/, 
      loader: 'babel'
    },
    { 
      test: /\.(eot(|\?v=4.5.0)|woff(|\?v=4.5.0)|woff2(|\?v=4.5.0)|ttf(|\?v=4.5.0)|svg(|\?v=4.5.0))$/, 
      loader: 'file'
    },
  ]
};

wecpackConfig.plugins = [new webpack.HotModuleReplacementPlugin()];
wecpackConfig.entry.app.unshift("webpack-dev-server/client?http://localhost:9999", "webpack/hot/dev-server");
var compiler = webpack(wecpackConfig);
var server = new webpackDevServer(compiler, {
  hot: true
});
server.listen(9999);

output.path配置的不对，要配置绝对路径，如下：
```
output: {
    path: __dirname + '/assets/',
    publicPath: './assets/',
    filename: 'bundle.js'
}
```

你应该设置 output.path 是一个绝对路径

output: {
        path: __dirname + '/assets/',
        publicPath: './assets/',
        filename: 'bundle.js'
    },
