我在 dist/css 下遇到了重复 css 文件的问题
我的 webpack 配置如下：
webpack.base.config.js
/* eslint quote-props: ['off'] */
'use strict'
const path = require('path')
const utils = require('./utils')
const config = require('../config')
const vueLoaderConfig = require('./vue-loader.conf')
const MiniCssExtractPlugin = require('mini-css-extract-plugin');
const isProduction = process.env.NODE_ENV === 'production';
function resolve (dir) {
return path.join(__dirname, '..', dir)
}
const createLintingRule = () => ({
test: /\.(js|vue)$/,
loader: 'eslint-loader',
enforce: 'pre',
include: [resolve('src'), resolve('test')],
options: {
formatter: require('eslint-friendly-formatter'),
emitWarning: !config.dev.showEslintErrorsInOverlay
}
})
module.exports = {

app: './src/entry.client.js'
},
output: {

module.exports = webpackConfig我检查了两个文件的内容，其中一个是由 OptimizeCSSAssetsPlugin 压缩的，另一个不是。
我还想问一下为什么这个 css 块没有 brotli 和 gziped 版本。
谢谢
