    引入了一张 css 文件样式没有改变 改成 scss 就可以~附上 vue.config.js 配置'use strict'const path = require('path')function resolve(dir) { return path.join(__dirname, dir)}const name = '' // page title// If your port is set to 80,// use administrator privileges to execute the command line.// For example, Mac: sudo npm run// You can change the port by the following methods:const port = process.env.port || process.env.npm_config_port || 8080 // dev port// All configuration item explanations can be find in https://cli.vuejs.org/config/module.exports = { /** * You will need to set publicPath if you plan to deploy your site under a sub path, * for example GitHub Pages. If you plan to deploy your site to https://foo.github.io/bar/, * then publicPath should be set to "/bar/". * In most cases please use '/' !!! * Detail: https://cli.vuejs.org/config/#publicpath */ publicPath: './', outputDir: 'dist', assetsDir: 'static', lintOnSave: process.env.NODE_ENV === 'development', productionSourceMap: false, devServer: { port: port, open: false, overlay: { warnings: false, errors: true }, proxy: { '/': { target: process.env.VUE_APP_BASE_API, ws: false, changeOrigin: true, pathRewrite: { '^/': '/' } } } // before: require('./mock/mock-server.js') }, configureWebpack: { // provide the app's title in webpack's name field, so that // it can be accessed in index.html to inject the correct title. name: name, resolve: { alias: { '@': resolve('src'), '@crud': resolve('src/components/Crud'), '@components': resolve('src/components') // mock: resolve('mock') } } }, chainWebpack(config) { config.plugin('style-loader') // it can improve the speed of the first screen, it is recommended to turn on preload config.plugin('preload').tap(() => [ { rel: 'preload', // to ignore runtime.js // https://github.com/vuejs/vue-cli/blob/dev/packages/@vue/cli-service/lib/config/app.js#L171 fileBlacklist: [/\.map$/, /hot-update\.js$/, /runtime\..*\.js$/], include: 'initial' } ]) // when there are many pages, it will cause too many meaningless requests config.plugins.delete('prefetch') // set svg-sprite-loader config.module .rule('svg') .exclude.add(resolve('src/icons')) .end() config.module .rule('icons') .test(/\.svg$/) .include.add(resolve('src/icons')) .end() .use('svg-sprite-loader') .loader('svg-sprite-loader') .options({ symbolId: 'icon-[name]' }) .end() config.when(process.env.NODE_ENV !== 'development', config => { config .plugin('ScriptExtHtmlWebpackPlugin') .after('html') .use('script-ext-html-webpack-plugin', [ { // `runtime` must same as runtimeChunk name. default is `runtime` inline: /runtime\..*\.js$/ } ]) .end() config.optimization.splitChunks({ chunks: 'all', cacheGroups: { libs: { name: 'chunk-libs', test: /[\\/]node_modules[\\/]/, priority: 10, chunks: 'initial' // only package third parties that are initially dependent }, elementUI: { name: 'chunk-elementUI', // split elementUI into a single package priority: 20, // the weight needs to be larger than libs and app or it will be packaged into libs or app test: /[\\/]node_modules[\\/]_?element-ui(.*)/ // in order to adapt to cnpm }, commons: { name: 'chunk-commons', test: resolve('src/components'), // can customize your rules minChunks: 3, // minimum common number priority: 5, reuseExistingChunk: true } } }) // https:// webpack.js.org/configuration/optimization/#optimizationruntimechunk config.optimization.runtimeChunk('single') }) }}
