这里是我的主要文件：

webpack.config.js

const webpack = require('webpack') 
const ExtractTextPlugin = require("extract-text-webpack-plugin") 
const path = require('path') 
const extractSass = new ExtractTextPlugin({ 
    filename: "styles.css", 
}); 
const VENDOR_LIBS = [ 
    'react', 'lodash', 'redux', 'react-redux', 'react-dom', 'react-input-range', 'redux-form', 'redux-thunk' 
]; 
module.exports = { 
    entry: { 
     bundle: './src/index.js', 
     vendor: VENDOR_LIBS 
    }, 
    output: { 
     filename: '[name].[chunkhash].js',

    },

      }, 
      { 
       test: /\.(scss)$/, 
       use: extractSass.extract({ 
        fallback: 'style-loader', 
        //resolve-url-loader may be chained before sass-loader if necessary 
        use: [{ 
         loader: "css-loader" // translates CSS into CommonJS 
        }, { 
         loader: "sass-loader" // compiles Sass to CSS 
        }] 
       }) 
      },

       loader: 'file-loader' 
      } 
     ] 
    }, 
    plugins: [ 
     new webpack.ProvidePlugin({ 
      $: "jquery", // Used for Bootstrap JavaScript components 
      jQuery: "jquery", // Used for Bootstrap JavaScript components 
      Tether: 'tether',

它应该显示HTML页的 “阵营简单首发”，但它没有。

请帮帮忙，让你想看其他文件

PS我知道：我很新用的WebPack

回答：

{ 
    "presets": [ 
     ["react"], 
     ["env"] 
    ], 
} 

const store = createStore(reducers) //assuming reducers is your combined reducers 
... 
<Provider store={store}> 

const createStoreWithMiddleware = applyMiddleware()(createStore); 
... 
<Provider store={createStoreWithMiddleware(reducers)}>
