javascript - webpack+babel npm 不想启动

Question

super 有善意的人!我只是这个神奇的魔法工艺的初学者，比如编程:)而且我有这样的能力 问题。基本上我知道 web pack 告诉我出了什么问题，但是 不过，我可以修复它:( 这是我的 webpack.config.js :

const path = require('path') 
const webpack = require('webpack')
const ExtractTextPlugin = require('extract-text-webpack-plugin')

module.exports = {
entry: [
'babel-polyfill',  
'./js/index.js',
'./js/nav.js'
'./scss/main.scss',
],
output: {
filename: 'index.js', 
libraryTarget: 'commonjs',
path: path.resolve('./dist/'),
},
module: {
rules: [
  {
    test: /\.css$/,
    loader: ExtractTextPlugin.extract(['css-loader']),
  },
  {
    test: /\.(sass|scss)$/,
    loader: ExtractTextPlugin.extract(['css-loader', 'sass-
 loader','babel-loader']),
  },
  {
    test: /\.(png|jpg|gif|svg)$/,
    use: [
      {
        loader: 'url-loader',
        options: {
          limit: 8192
        }
      }
    ]
  },
    {
  test: /\.js$/,
  exclude: /(node_modules|bower_components)/,
  use: {
    loader: 'babel-loader',
    options: {
      presets: ['@babel/preset-env']
    }
  }
 },


  ]
 },
 plugins: [
 new webpack.optimize.UglifyJsPlugin({
  output: {
    comments: false
  }
 }),
  new ExtractTextPlugin({
  filename: 'styles.css',
  allChunks: true,
}),
]
}

my package.json :

{
"name": "simple-webpack-boilerplate",
"version": "0.0.1",
"scripts": {
"start": "webpack --config webpack.config.js --watch",
"build": "webpack --config webpack.config.js"
},
"babel": {
"presets": [
  "es2015"
 ]
 },

"dependencies": {
"@babel/core": "^7.0.0-beta.35",
"@babel/preset-env": "^7.0.0-beta.35",
"init": "^0.1.2"
}
 }

最后，当我尝试启动 npm 时，我在终端上出现的错误 :

`> simple-webpack-boilerplate@0.0.1 start 
/Users/Niemiec/Desktop/michal_web
> webpack --config webpack.config.js --watch

/Users/Niemiec/Desktop/michal_web/webpack.config.js:10

请帮忙!!

您的 entry 列表中似乎缺少 ,。尝试一下:

entry: [
    'babel-polyfill',  
    './js/index.js',
    './js/nav.js'
    './scss/main.scss',
],
