和我的webpack配置文件
const path = require('path')
const HtmlWebpackPlugin = require('html-webpack-plugin')
const copyWebpackPlugin = require('copy-webpack-plugin')
const MiniCssExtractPlugin = require('mini-css-extract-plugin');
const ROOT_DIRECTORY = path.join(__dirname,'..')
const SRC_DIRECTORY = path.join(ROOT_DIRECTORY,'src')
const devMode = process.env.NODE_ENV !== 'production';
const plugins = [];
plugins.push(new HtmlWebpackPlugin({
template: path.join(SRC_DIRECTORY,'')
})
);
plugins.push( new copyWebpackPlugin({
patterns: [
{ from: path.join(SRC_DIRECTORY,'assets'),to: path.join(ROOT_DIRECTORY,'build') }
],}));
plugins.push(new MiniCssExtractPlugin())
const config = {
entry: [path.resolve(__dirname,'../src/index.js')],output: {
globalObject: "this",path: path.resolve(__dirname,'../build'),// filename: 'bundle.js',filename: '[name].[hash:8].js',sourceMapFilename: '[name].[hash:8].map',chunkFilename: '[id].[hash:8].js',publicPath: '/',},mode: 'development',resolve: {
modules: [path.resolve('node_modules'),'node_modules'],extensions: [".jsx",".js"]
},performance: {

module.exports = config
该如何避免该错误? 面对这个问题一段时间。无法确定。我的代码有任何错误吗?.webpack的新手。
