【问题描述】:
嗨,我在我的应用程序中使用套接字 io。这需要 fs。当我尝试使用下面的 webpack 配置捆绑我的 javascript 时。我收到错误无法解析“fs”。
Module not found: Error: Can't resolve 'fs' in 'my application path/node_modules/socket.io/lib'
我通过添加 target:'node' 和 node:{fs:'empty'} 找到。这个问题得到了解决。
但是 sass-loader 有一个问题。出现以下错误。
ERROR in javascript/bundle.js from UglifyJs
Unexpected token: name (zlibLimiter) [javascript/bundle.js:60019,4]
Child extract-text-webpack-plugin ../../../node_modules/extract-text-webpack-plugin/dist ../../../node_modules/css-loader/index.js??ref--2-2!../../../node_modules/sass-loader/lib/loader.js!s
忽略上述错误运行应用程序。低于错误。

下面是我的 webpack 配置和版本。谁能帮我解决这个问题。
"webpack": "~3.6.0", npm -v 5.8.0 节点 -v v8.4.0
const webpack = require('webpack');
const env = process.env.NODE_ENV;
const ExtractTextPlugin = require('extract-text-webpack-plugin');
const path = require('path');
const extractSass = new ExtractTextPlugin({
filename: 'css/[name].css',
allChunks: false
});
let output = {
path: __dirname + '/src/main/resources/static/',
filename: 'javascript/[name].js'
};
if (env === 'debug' || env === 'nondev') {
output = {
