[Webpack在尝试构建JSX时抛出错误

Question

关于这个问题的答案如此之多，我发誓我已经尝试了全部。我不确定配置设置有什么问题

在终端中运行webpack时出现的错误：

ERROR in ./src/index.js 13:8
Module parse failed: Unexpected token (13:8)
You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders
|     // const store = createStore(reducers, {}, applyMiddleware(ReduxThunk));
|     return (
>         <HomeShell/>
|     );
| };

我的index.js

import "@babel/polyfill";
import React from 'react';
import ReactDOM from 'react-dom';
import HomeShell from "./HomeShell";

const Root  = () => {

    return (
        <HomeShell/>
    );
};


ReactDOM.render(<Root />, document.getElementById('#main'));

^^ HomeShell是带有React组件的js文件，它们都是js文件。

我的webpack.config.cjs

import path from 'path';

module.exports = {
    entry: ["@babel/polyfill", "./src/index.js"],
    output: {
        path: path.resolve(__dirname, 'public'),
        filename: 'bundle.js'

    },
    target: "web",
    mode: 'production',
    module: {
        rules: [
            {
                test: /\.m?js$/,
                include: /src/,
                exclude: /node_modules/,
                use: {
                    loader: 'babel-loader',
                    options: {
                        presets: ["@babel/preset-env", "@babel/preset-react"]
                    }
                }
            },
            {
                test: /\.css$/,
                include: /node_modules/,
                loader: ['style-loader', 'css-loader'],
            }
        ]
    },
};

  "presets": ["@babel/preset-env", "@babel/preset-react"]
}

我距离react / webpack / babel的专家还很远，但是这个确切的设置似乎可以在我运行的另一个基本应用程序上正常工作。不确定两个应用程序之间我在做什么不同。

Answer 1

在.babelrc文件以及加载程序选项中。也许有冲突。
