1. 在項目根目錄創建vue.config.js文件

2. 代碼如下

module.exports = {
    
    // 輸出文件目錄
    outputDir: 'dist',
    // eslint-loader 是否在保存的時候檢查
    lintOnSave: true,
    // use the full build with in-browser compiler?
    // https://vuejs.org/v2/guide/installation.html#Runtime-Compiler-vs-Runtime-only
    // compiler: false,
    // webpack配置
    // see https://github.com/vuejs/vue-cli/blob/dev/docs/webpack.md
    chainWebpack: () => {},
    configureWebpack: () => {},
    // vue-loader 配置項
    // https://vue-loader.vuejs.org/en/options.html
    // vueLoader: {},
    // 生產環境是否生成 sourceMap 文件
    productionSourceMap: true,
    // css相關配置
    css: {
     // 是否使用css分離插件 ExtractTextPlugin
     extract: true,
     // 開啓 CSS source maps?
     sourceMap: false,
     // css預設器配置項
     loaderOptions: {},
     // 啓用 CSS modules for all css / pre-processor files.
     modules: false
    },
    // use thread-loader for babel & TS in production build
    // enabled by default if the machine has more than 1 cores
    parallel: require('os').cpus().length > 1,
    // 是否啓用dll
    // See https://github.com/vuejs/vue-cli/blob/dev/docs/cli-service.md#dll-mode
