运行webpack时出现终端错误“ multi babel-polyfill中的错误”？

Question

运行命令npm run start时，在终端中出现以下错误。

ERROR in multi babel-polyfill ./src/index.js
Module not found: Error: Can't resolve './src/index.js' in '/Users/nezihdogruer/Desktop/jonas2/9-forkify/starter'
 @ multi babel-polyfill ./src/index.js app[1]

ERROR in multi (webpack)-dev-server/client?http://localhost:8080 babel-polyfill ./src/index.js
Module not found: Error: Can't resolve './src/index.js' in '/Users/nezihdogruer/Desktop/jonas2/9-forkify/starter'
 @ multi (webpack)-dev-server/client?http://localhost:8080 babel-polyfill ./src/index.js app[2]

我正确下载了webpack和babel polyfill，并将babel polyfill保存为包括axios在内的常规依赖项。

由于某种原因，我无法创建.babelrc文件，尽管也许与它有关？

我的webpack配置文件设置如下。

const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');

module.exports = {
    entry: {

        app: ['babel-polyfill',
              './src/index.js']
    },

    output: {

        path: path.resolve(__dirname, 'dist'),
        filename: 'js/bundle.js'

    },
    devServer: {

        contentBase: './dist'
    },
    plugins: [
       new HtmlWebpackPlugin({

            filename: 'index.html',
            template: './src/index.html'
        })
    ],
    module: {
        rules: [
            {
                test: /\.js$/,
                exclude: /node_modules/,
                use: {
                    loader: 'babel-loader'
                }
            }
        ]
    }
};

入口点可能有问题吗？ 我将不胜感激。 谢谢。
