TailwindCSS 3 + Symfony / webpack Encore 没有样式？

Question

我在 symfony 6 应用程序中更新到 TailwindCSS 3。当我编译样式表时没有错误（它编译成功）但是顺风 class 样式的 none 工作。我注意到 tailwind 的导入似乎没有从 @tailwindcss 调用中翻译（它们只是按原样包含在浏览器中）。也许是 postCSS 问题？

webpack.config.js:

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

// Manually configure the runtime environment if not already configured yet by the "encore" command.
// It's useful when you use tools that rely on webpack.config.js file.
if (!Encore.isRuntimeEnvironmentConfigured()) {
    Encore.configureRuntimeEnvironment(process.env.NODE_ENV || 'dev');
}

Encore
    // directory where compiled assets will be stored
    .setOutputPath('public/build/')
    // public path used by the web server to access the output path
    .setPublicPath('/build')
    // only needed for CDN's or sub-directory deploy
    //.setManifestKeyPrefix('build/')

    .copyFiles([
        {
            from: './assets/images',
            to: 'images/[path][name].[ext]',
        }
    ])

    /*
     * ENTRY CONFIG
     *
     * Each entry will result in one JavaScript file (e.g. app.js)
     * and one CSS file (e.g. app.css) if your JavaScript imports CSS.
     */

    .addEntry('main', './assets/main.js')

    .addEntry('admin', './assets/admin.js')

    // When enabled, Webpack "splits" your files into smaller pieces for greater optimization.
    .splitEntryChunks()

    // will require an extra script tag for runtime.js
    // but, you probably want this, unless you're building a single-page app
    .enableSingleRuntimeChunk()

    /*
     * FEATURE CONFIG
     *
     * Enable & configure other features below. For a full
     * list of features, see:
     * https://symfony.com/doc/current/frontend.html#adding-more-features
     */
    .cleanupOutputBeforeBuild()
    .enableBuildNotifications()
    .enableSourceMaps(!Encore.isProduction())
    // enables hashed filenames (e.g. app.abc123.css)
    .enableVersioning(Encore.isProduction())

    .configureBabel((config) => {
        config.plugins.push('@babel/plugin-proposal-class-properties');
    })

    // enables @babel/preset-env polyfills
    .configureBabelPresetEnv((config) => {
        config.useBuiltIns = 'usage';
        config.corejs = 3;
    })

    // enables Sass/SCSS support
    .enableSassLoader()

    // Enable PostCSS loader
    .enablePostCssLoader((options) => {
        options.postcssOptions = {
            // the directory where the postcss.config.js file is stored
            config: './postcss.config.js',
        };
    })

    .splitEntryChunks()
;

module.exports = Encore.getWebpackConfig();

postcss.config.js:

let tailwindcss = require('tailwindcss');

module.exports = {
    plugins: [
        tailwindcss('./tailwind.config.js'),
        require('postcss-import'),
        require('autoprefixer')
    ]
}

tailwind.config.js:

module.exports = {
    darkMode: 'media'
}

main.css（通过 main.js 导入）：

@import '~tailwindcss/base';
@import '~tailwindcss/components';
@import '~tailwindcss/utilities';

/* Rest of custom content... */

我在各种配置文件中添加了 console.log()s，它们都显示为 loaded/accessed。

我遇到过类似的问题。我认为在新的顺风中，您应该始终添加模板的位置并执行以下操作：

const defaultTheme = require('tailwindcss/defaultTheme');
module.exports = {
    content: [
        "./assets/**/*.{vue,js,ts,jsx,tsx}",
        "./templates/**/*.{html,twig}",
    ],
    theme: {
      extend: {
          fontFamily: {
              sans: ['Inter var', ...defaultTheme.fontFamily.sans],
          },
      }
    },
    plugins: [],
}
