我的index.js 文件中有以下导入

import React,  Component  from 'react';
import ReactDOM from 'react-dom';
import 'core-js/fn/promise';

我的 webpack 设置为

var HTMLWebpackPlugin = require('html-webpack-plugin');
var HTMLWebpackPluginConfig = new HTMLWebpackPlugin(
    template: __dirname + '/app/index.html',
    filename: 'index.html',
    inject: 'body'
);

const ExtractTextPlugin = require("extract-text-webpack-plugin");

const extractSass = new ExtractTextPlugin(
    filename: "[name].[contenthash].css",
    disable: process.env.NODE_ENV === "development"
);

module.exports = 
    entry : __dirname + '/app/index.js',
    module: 
         rules: [
            
                test: /\.js$/,
                exclude: /node_modules/,
                use: 
                    loader: 'babel-loader'
                
             ,
            
                test: /\.scss$/,
                use: [
                    loader: "style-loader"
                , 
                    loader: "css-loader"
                , 
                    loader: "sass-loader",
                ]
            
        ],
    ,
    output: 
        filename: 'transformed.js',
        path: __dirname + '/docs'
    ,
    plugins: [
        HTMLWebpackPluginConfig,
        extractSass,
        new ExtractTextPlugin("styles.css")
    ]

【问题讨论】：

其他浏览器我得到一个状态错误，我想在这里解决，***.com/questions/48062682/…

【参考方案1】：

有同样的问题，想避免npm run eject，所以我在 index.html 中包含了这个脚本，同时处于开发模式：

<script src="//cdn.polyfill.io/v2/polyfill.min.js"></script>

它适用于 React v16.6.3 中的 npx create-react-app my-app 版本 1

我还需要测试生产，但 127.0.0.1 对我也不起作用，所以我使用带有命令 netlify deploy 的 netlify 并且它起作用了。

【参考方案2】：

我已将我的webpack 和babelrc 更新为以下内容，现在可以使用了。

.babelrc

  "presets": [
    'es2015', "react",
  ]

webpack.config.js

module.exports = 
    entry : [__dirname + '/app/index.js'],
    module: 
         rules: [
            
                test: /\.js$/,
                exclude: /node_modules/,
                use: 
                    loader: 'babel-loader'
                
             ,
            
                test: /\.scss$/,
                use: [
                    loader: "style-loader"
                , 
                    loader: "css-loader"
                , 
                    loader: "sass-loader",
                ]
            
        ],
    ,
    output: 
        filename: 'bundle.js',
        path: __dirname + '/docs'
