Symfony4，无法使用 webpack 缩小 CSS

Question

我有一个 symfony 4 Web 应用程序，我正在尝试缩小 CSS，但它不起作用。我已经尝试了几个小时，但一直无法让它提供缩小版本。难道我做错了什么？

webpack.config.js

var Encore = require('@symfony/webpack-encore');

Encore
    // the project directory where compiled assets will be stored
    .setOutputPath('public/build/')
   // the public path used by the web server to access the previous 
directory
    .setPublicPath('/build')
    .cleanupOutputBeforeBuild()
    .enableSourceMaps(!Encore.isProduction())

    .splitEntryChunks()
    .enableSingleRuntimeChunk()
    .enablePostCssLoader()


    // uncomment to create hashed filenames (e.g. app.abc123.css)
    // .enableVersioning(Encore.isProduction())

    // uncomment to define the assets of the project
     .addEntry('js/app', './assets/js/app.js')
    // .addStyleEntry('css/app', './assets/css/app.scss')

    // uncomment if you use Sass/SCSS files
    // .enableSassLoader()

    // uncomment for legacy applications that require $/jQuery as a 
global variable
    // .autoProvidejQuery()



;


module.exports = Encore.getWebpackConfig();

postcss.config.js

module.exports = {
    plugins: {
        // include whatever plugins you want
        // but make sure you install these via yarn or npm!

        // add browserslist config to package.json (see below)
        autoprefixer: {}
    }
}

您需要编译您的资产以用于生产yarn encore production

我不确定，但npm encore productionor 也./node_modules/.bin/encore production应该有效。
