react 使用webpack打包问题汇总-白红宇

一、TypeError: src\foo.js: Cannot read property 'bindings' of null 问题原因： 1.babel-loader一系列包的版本不兼容有冲突，需要检查版本，下面是能够成功运行的版本的版本组合： "@babel/plugin-proposal-class-properties": "^7.1.0", "babel-core": "^7.0.0-bridge.0", "babel-loader": "^7.1.5", "babel-preset-env": "^2.0.0-alpha.20", "babel-preset-es2015": "^7.0.0-beta.3", "babel-preset-react": "^7.0.0-beta.3", 2.rules配置的时候没有将node_modules exclude掉，例子：

{                test: /\.js?$/,                exclude: path.resolve(__dirname, "node_modules"),                include: path.resolve(__dirname, "src"),                use: {                    loader: 'babel-loader',                    options: {                        presets: ['env', 'react'],                        plugins: [                            ["@babel/plugin-proposal-class-properties", { "loose": true }]                        ]                    },                }}复制代码

二、工程中涉及到antd框架的时候，应该如何配置？

const path = require('path');const HtmlWebpackPlugin = require('html-webpack-plugin');module.exports = {    mode: "development",    entry: path.resolve(__dirname, "./src/index.js"),    output: {        path: path.resolve(__dirname, "dist")    },    devServer: {        contentBase: path.join(__dirname, "dist"),        compress: true,        port: 3000    },    resolve: {        extensions: ['.js', '.jsx', '.less']    },    module: {        rules: [            {                test: /\.css?$/,                include: [path.join(__dirname, 'src'), path.join(__dirname, 'node_modules/antd')],                use: [ 'style-loader', 'css-loader']            },            {                test: /\.less?$/,                include: [path.join(__dirname, 'src'), path.join(__dirname, 'node_modules/antd')],                use: {                    loader: "less-loader",                    options:{                        javascriptEnabled: true                    }                }            },            {                test: /\.js?$/,                use: {                    loader: 'babel-loader',                    options: {                        presets: ['env', 'react'],                        plugins: [                            ["@babel/plugin-proposal-class-properties", { "loose": true }],["import", { "libraryName": "antd", "style": "css" }],#按需加载antd里面的组件                        ]                    },                }            },            {                test: /\.(ico|png|svg|jpg|gif)$/,                exclude: path.resolve(__dirname, "node_modules"),                include: path.resolve(__dirname, "src"),                use: [                    {                        loader: 'file-loader',                        options: {}                    }                ]            }        ]    },    plugins: [        new HtmlWebpackPlugin({template: './public/index.html'})    ]};复制代码
