Javascript 网页包+；巴贝尔npm不想开始

超级善意的人！！我只是这门神奇的技艺的初学者，比如编程：）我有这种能力 问题基本上我知道，所以WebPack会告诉我出了什么问题，但是 尽管如此，我还是可以解决它：（ 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 :

{

最后，当我尝试启动npm时，终端上的错误 :

救命啊

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

逗号位置不正确，您应该将

，

从

。/scss/main.scss'

上面的一行移动到

。/js/nav.js'

，看起来您的

条目

列表中缺少了一个

，

。尝试一下：

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

为什么你要在css文件上使用“babel loader”？你还有其他js代码吗？入口点语法错误基本上我有nav.js我可能会多放一些..我不太确定..关于babel loader我想是的，如果我想用我的js使用babel，它需要它..ups..看起来我比我想的更糟..）./node_modules/css loader！中出错/node_modules/sass loader/lib/loader.js/节点\模块/babel加载程序/lib/scss/main.scss模块生成失败：错误：找到多个配置文件。请删除一个：-.babelrc-package.json，但我找不到一个babelrc文件…babelrc应该在您的根目录中，可能您看不到它，因为它以点开头，所以它是隐藏的。尝试在根目录上运行命令

ls-a

。好的，我现在可以运行npm，但是…现在…ehgg在./node\u modules/css loader！中出现类似的错误/node_modules/sass loader/lib/loader.js/节点\模块/babel加载程序/lib/scss/main.scss模块生成失败：错误：找到多个配置文件。请删除一个：-.babelrc-package.json我的问题是..在哪里可以找到babelrc文件？
