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 }]]},}
}

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'})]
};
