const htmlpugin = new HtmlWebPackPlugin({
    template:path.join(__dirname,'./src/index.html'),
    filename:'index.html'

    mode:'development',
    plugins: [

.babelrc

{
  "presets": [
       "env","react", "stage-0"
  ],
  "plugins": [
        "transform-runtime"

}

只需要將這三個文件複製黏貼到自己的項目，然後npm install即可
babel版本不同是個大坑，我這個版本組合可以使用僅供參考！！！
