求助：如何修复React Native Reanimated引发的Babel解析错误？

问题场景 #

整合代码时遇到react-native-reanimated的web端编译错误，具体报错：

./node_modules/react-native-reanimated/lib/index.web.js 3:9
Module parse failed: Unexpected token (3:9)
File was processed with these loaders:

• ../../../AppData/Roaming/npm/node_modules/expo-cli/node_modules/babel-loader/lib/index.js
  You may need an additional loader to handle the result of these loaders.
  | import "./reanimated2/js-reanimated/global";
  | export * from "./reanimated2";

export * as default from "./Animated";

解决思路 #

• 校验版本兼容性：react-native-reanimated v2及以上版本要求Babel 7.12+，同时确保babel-loader版本与项目Babel版本匹配，避免版本不兼容导致语法解析失败。
• 配置Babel插件：在项目的babel.config.js（或.babelrc）中添加react-native-reanimated/plugin插件，注意插件需放在预设之后，示例配置：

module.exports = {
  presets: ['babel-preset-expo'],
  plugins: ['react-native-reanimated/plugin'],
};

• 清除编译缓存：执行缓存重置命令，清除旧的编译产物：
  • Expo项目：expo r -c
  • React Native项目：npx react-native start --reset-cache
• 调整Webpack配置：由于报错来自web端文件，需确保webpack让babel-loader处理react-native-reanimated模块，修改webpack.config.js：

const path = require('path');

module.exports = {
  module: {
    rules: [
      {
        test: /\.(js|jsx|ts|tsx)$/,
        include: [
          path.resolve(__dirname, 'src'),
          path.resolve(__dirname, 'node_modules/react-native-reanimated'),
        ],
        use: 'babel-loader',
      },
    ],
  },
};

• 重装依赖：删除node_modules、package-lock.json（或yarn.lock），重新执行npm install或yarn install，确保依赖完整无损坏。
