React Native iOS pod install报错：无法找到React-RCTFabric依赖

执行pod install时触发如下错误：

Unable to find a specification for 'React-RCTFabric' depends upon by 'RNGestureHandler'

项目Android端可正常构建，但iOS端始终无法完成Pod安装。已尝试清理node_modules重装依赖、替换为react-native init生成的默认Podfile，问题均未解决。

# If you are using a `react-native-flipper` your iOS build will fail when `NO_FLIPPER=1` is set.
# because `react-native-flipper` depends on (FlipperKit,...) that will be excluded
#
# To fix this you can also exclude `react-native-flipper` using a `react-native.config.js`
# ```js
# module.exports = {
#   dependencies: {
#     ...(process.env.NO_FLIPPER ? { 'react-native-flipper': { platforms: { ios: null } } } : {}),
# ```
flipper_config = ENV['NO_FLIPPER'] == "1" ? FlipperConfiguration.disabled : FlipperConfiguration.enabled

解决方法 #

1. 强制关闭Fabric新架构

React Native 0.71默认禁用Fabric，但你的Podfile中使用了flags[:fabric_enabled]，可能存在环境变量误开启的情况。直接在Podfile中强制关闭：
修改use_react_native!中的配置项：

:fabric_enabled => false,

或者在项目根目录创建.xcode.env.local文件，添加：

RCT_NEW_ARCH_ENABLED=0

2. 升级react-native-gesture-handler

当前使用的~2.5.0版本可能对Fabric有不必要的依赖，升级到适配RN 0.71的最新稳定版：

npm install react-native-gesture-handler@latest

之后进入ios目录重新执行pod install。

3. 彻底清理Pod缓存

执行以下命令清除所有Pod相关缓存和文件，重新安装：

cd ios
pod deintegrate
rm Podfile.lock
rm -rf ~/Library/Caches/CocoaPods
rm -rf Pods
pod install

4. 检查本地依赖包

确认项目中的本地包visualtis-messaging-service没有引入对Fabric的依赖，避免与主项目冲突。
