React Native 升级到 74 后出现 React-Fabric 错误

Question

我正在尝试对旧项目进行一些更新，并面临支持新 iOS 版本更新带来的常见问题。运行一些 npm 更新和 React Native 升级后，我能够成功安装 pod，但现在当我运行 ios 时，它无法构建并出现以下错误：

The following build commands failed:
    PhaseScriptExecution [CP-User]\ [RN]Check\ rncore .../Build/Intermediates.noindex/Pods.build/Debug-iphonesimulator/React-Fabric.build/Script-EC9C377125AD0589400F123D2D4CB2D3.sh (in target 'React-Fabric' from project 'Pods')

这是我的反应本机信息：

我有什么想法可以开始解决这个问题吗？

更新

深入挖掘后，这是失败的构建文件：

echo "Checking whether Codegen has run..."
rncorePath="$REACT_NATIVE_PATH/ReactCommon/react/renderer/components/rncore"

if [[ ! -d "$rncorePath" ]]; then
  echo 'error: Codegen did not run properly in your project. Please reinstall cocoapods with `bundle exec pod install`.'
  exit 1
fi

因此，由于某种原因，

$REACT_NATIVE_PATH/ReactCommon/react/renderer/components/rncore

路径不存在。我不确定为什么，我会继续研究。

Answer 1

由于某些 Pod 尝试使用低于我的 Podfile 中指定的最低支持版本，代码生成器似乎无法正常工作。我不确定为什么会这样，但我遇到了一个 github 问题，修复方法如下。

https://github.com/travis-mark/lrn/commit/015854716feadd61a904d5a603b027426472f863

该修复是一个安装后脚本，它使用 Podfile 中的最低 ios 版本覆盖 IPHONEOS_DEPLOYMENT_TARGET。
