React Native 0.70.3 iOS模拟器报错求助：TypeError读取source属性失败

升级React Native到0.70.3后，iOS模拟器运行项目时触发报错：

TypeError: Cannot read property 'source' of undefined, js engine: hermes

项目package.json配置如下：

排查与解决步骤 #

• 定位报错来源：打开React Native Debugger或Chrome调试工具，查看完整调用栈，确认触发source读取操作的组件或第三方库。这类报错大概率是依赖库未适配RN 0.70的API变更。
• 升级兼容的第三方库：
  • react-native-camera已不再适配RN 0.70+，替换为官方推荐的react-native-vision-camera；
  • 将react-native-gesture-handler升级到2.0.0+版本，react-native-image-picker升级到5.0.0+版本，确保依赖库支持RN 0.70；
  • 检查react-native-fast-image、react-native-webrtc等库的版本，升级到对应兼容版本。
• 清理缓存并重建项目：
  • 执行npm cache clean --force清除npm缓存；
  • 进入iOS目录，删除Podfile.lock和Pods文件夹，重新执行pod install；
  • 重置模拟器缓存：打开模拟器后选择Hardware > Erase All Content and Settings；
  • 重启Metro服务：执行react-native start --reset-cache。
• 检查Hermes兼容性：RN 0.70默认启用Hermes，部分旧库可能不兼容。可临时修改iOS项目Podfile，将use_react_native!中的:hermes_enabled => true改为false，若报错消失，需替换或升级不兼容的库。
• 修复代码中的空值引用：排查项目代码中是否存在直接读取undefined对象的source属性的情况，添加空值判断（如obj?.source）避免报错。
