Question

我正在尝试使用Webpack设置一个React项目。这是一个简单的应用程序，可加载mdx文件并进行解析。当我尝试运行该应用程序时，它返回“未捕获的TypeError：path.parse不是函数”

我尝试从'path'导入解析，并从'path-browserify'导入解析，但仍然无法正常工作

index.js：

import React, { lazy, Component, Suspense } from "react";
import { importMDX } from "mdx.macro";
import ReactDOM from "react-dom";
// import path from "path";
// import { parse } from "path";
import path from "path-browserify";
// import { parse } from "path-browserify";

const Content = lazy(() => importMDX("./index.mdx"));

class App extends Component {
    render() {
        return (
            <div>
                <Suspense fallback={<div>Loading...</div>}>
                    <Content />
                </Suspense>
            </div>
        );
    }
}

ReactDOM.render(<App />, document.getElementById("root"));

webpack.config.js：

const HtmlWebPackPlugin = require("html-webpack-plugin");
const path = require("path");
module.exports = {
    entry: "./index.js",
    module: {
        rules: [
            {
                test: /\.(js|jsx)$/,
                exclude: /node_modules/,
                use: {
                    loader: "babel-loader"
                }
            },
            {
                test: /\.mdx?$/,
                use: ["babel-loader", "@mdx-js/loader"]
            },
            {
                test: /\.html$/,
                use: [
                    {
                        loader: "html-loader"
                    }
                ]
            }
        ]
    },
    plugins: [
        new HtmlWebPackPlugin({
            template: "./index.html",
            filename: "./index.html"
        })
    ],
    node: {
        fs: "empty",
        module: "empty"
    }
};

package.json：

{
    "name": "doc",
    "version": "1.0.0",
    "description": "",
    "main": "index.js",
    "scripts": {
        "start": "webpack-dev-server --open --mode development",
        "build": "webpack --mode production"
    },

        "react": "^16.9.0",
        "react-dom": "^16.9.0"
    }
}

错误：

您不需要为path包括额外的依赖项。 path是节点js的全局依赖项。

npm remove path或yarn remove path

和

npm remove path-browserify或yarn remove path-browserify

并清除节点缓存

npm clear cache

你可以试试吗？
