我已经初始化了一个新的Symfony项目，版本为6.3.3，并且想尝试使用React的symfony-ux。所以我遵循了这个指南：https://symfony.com/bundles/ux-react/current/index.html但是我无法在页面上渲染react组件。
我已经安装了所有的软件包，并有一个结构看起来像这样：enter image description here
然后我的controllers.json看起来像这样：

{
    "controllers": {
        "@symfony/ux-react": {
            "react": {
                "enabled": true,
                "fetch": "eager"
            }
        }
    },
    "entrypoints": []
}

我的bootstrap.js看起来像这样：

import { startStimulusApp } from '@symfony/stimulus-bridge';
// Registers Stimulus controllers from controllers.json and in the controllers/ directory
export const app = startStimulusApp(require.context(
    '@symfony/stimulus-bridge/lazy-controller-loader!./controllers',
    true,
    /\.[jt]sx?$/
));
// register any custom, 3rd party controllers here
// app.register('some_controller_name', SomeImportedController);

app.js看起来像这样：

import { registerReactControllerComponents } from '@symfony/ux-react';
import './bootstrap.js';
/*
 * Welcome to your app's main JavaScript file!
 *
 * We recommend including the built version of this JavaScript file
 * (and its CSS file) in your base layout (base.html.twig).
 */

// any CSS you import will output into a single css file (app.css in this case)
import './styles/app.css';

registerReactControllerComponents(require.context('./react/controllers', true, /\.(j|t)sx?$/));

你好，jsx看起来像这样：

import React from 'react';

export default function (props) {

   return <div>TESTING</div>;
}

在我的home.html.twig中，我有以下内容：

{% extends 'base.html.twig' %}

{% block body %}
    <div>
        Component should render below
        <div {{ react_component('Hello') }}>
          
        </div>
    </div>
{% endblock %}

我在日志中没有得到任何错误，所以安装的模块似乎一切正常。但是Hello.jsx react组件没有显示。只有我在模板中编写的其他东西。
然而，当检查时，我可以看到刺激已经将此内容放入div开始标记中：

data-controller=“symfony--ux-react--react”data-symfony--ux-react--react-component-value=“Hello”

但是里面的测试文本不会呈现在页面上。如果有人能帮我看看这个，我会很高兴：）
我的package.json看起来像这样：

{
    "devDependencies": {
        "@babel/core": "^7.17.0",
        "@babel/preset-env": "^7.16.0",
        "@babel/preset-react": "^7.22.5",
        "@hotwired/stimulus": "^3.0.0",
        "@symfony/stimulus-bridge": "^3.2.0",
        "@symfony/ux-react": "file:vendor/symfony/ux-react/assets",
        "@symfony/webpack-encore": "^4.0.0",
        "core-js": "^3.23.0",
        "react": "^18.2.0",
        "react-dom": "^18.0",
        "regenerator-runtime": "^0.13.9",
        "webpack": "^5.74.0",
        "webpack-cli": "^4.10.0",
        "webpack-notifier": "^1.15.0"
    },
    "license": "UNLICENSED",
    "private": true,
    "scripts": {
        "dev-server": "encore dev-server",
        "dev": "encore dev",
        "watch": "encore dev --watch",
        "build": "encore production --progress"
    }
}

EDIT以下是webpack.config的外观：

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

// 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 subdirectory deploy
    //.setManifestKeyPrefix('build/')

    /*
     * 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('app', './assets/app.js')

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

    // enables the Symfony UX Stimulus bridge (used in assets/bootstrap.js)
    .enableStimulusBridge('./assets/controllers.json')

    // 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())

    // configure Babel
    // .configureBabel((config) => {
    //     config.plugins.push('@babel/a-babel-plugin');
    // })

    // enables and configure @babel/preset-env polyfills
    .configureBabelPresetEnv((config) => {
        config.useBuiltIns = 'usage';
        config.corejs = '3.23';
    })

    // enables Sass/SCSS support
    //.enableSassLoader()

    // uncomment if you use TypeScript
    //.enableTypeScriptLoader()

    // uncomment if you use React
    .enableReactPreset()

    // uncomment to get integrity="..." attributes on your script & link tags
    // requires WebpackEncoreBundle 1.4 or higher
    //.enableIntegrityHashes(Encore.isProduction())

    // uncomment if you're having problems with a jQuery plugin
    //.autoProvidejQuery()
;

module.exports = Encore.getWebpackConfig();

和base.html.twig：
