我的webpack配置有什么问题吗？我在网上跟随教程说到配置的方式相同。但我想我一定错过了什么？
有谁能指出？谢谢
webpack.common.js
const path = require('path');
const CleanWebpackPlugin = require('clean-webpack-plugin');
// const HtmlWebpackPlugin = require('html-webpack-plugin');
function resolve (dir) {
return path.join(__dirname, '..', dir)

我好意思我忘了实际让webpack通过添加条目来查看scss文件。基本上只是在library-global-styles.scss中执行@import '...'。但是很想知道怎么做才能打破它们取决于文件名虽然......
entry: {
...
'library-global-styles': './src/library-global-styles.scss'
},
