React Native iOS构建失败：React Logger与glog相关报错求助

问题概述 #

Android端运行正常，但执行npx react-native run-ios或直接通过Xcode构建均失败，核心报错包含Swift Package的Docs.docc加载冲突，以及React-logger模块编译失败。

命令行报错详情 #

** BUILD FAILED **


The following build commands failed:
        CompileC /Users/shubhagarwal/Library/Developer/Xcode/DerivedData/weedlemobiledapptraining-cngaloxjuncutwengkgnppfnmbtd/Build/Intermediates.noindex/Pods.build/Debug-iphonesimulator/React-logger.build/Objects-normal/x86_64/react_native_log.o /Users/shubhagarwal/Desktop/metawork/portal-react-native/node_modules/react-native/ReactCommon/logger/react_native_log.cpp normal x86_64 c++ com.apple.compilers.llvm.clang.1_0.compiler (in target 'React-logger' from project 'Pods')

Xcode构建时也弹出同类错误提示，核心内容与命令行报错一致。

当前Podfile配置 #

require File.join(File.dirname(`node --print "require.resolve('expo/package.json')"`), "scripts/autolinking")
require File.join(File.dirname(`node --print "require.resolve('react-native/package.json')"`), "scripts/react_native_pods")
require File.join(File.dirname(`node --print "require.resolve('@react-native-community/cli-platform-ios/package.json')"`), "native_modules")
require 'json'
podfile_properties = JSON.parse(File.read(File.join(__dir__, 'Podfile.properties.json'))) rescue {}
$RNFirebaseAsStaticFramework = true
platform :ios, podfile_properties['ios.deploymentTarget'] || '12.0'
install! 'cocoapods',
:deterministic_uuids => false


target 'weedlemobiledapptraining' do
  use_expo_modules!
  use_modular_headers!
  # use_frameworks!

  config = use_native_modules!
  # use_frameworks! :linkage => podfile_properties['ios.useFrameworks'].to_sym if podfile_properties['ios.useFrameworks']

  # Flags change depending on the env values.
  flags = get_default_flags()

  use_react_native!(
    :path => config[:reactNativePath],
    :hermes_enabled => flags[:hermes_enabled] || podfile_properties['expo.jsEngine'] == 'hermes',
    :fabric_enabled => flags[:fabric_enabled],
    # An absolute path to your application root.
    :app_path => "#{Dir.pwd}/.."
  )

  # Uncomment to opt-in to using Flipper
  # Note that if you have use_frameworks! enabled, Flipper will not work
  #
  # if !ENV['CI']
  #   use_flipper!()
  # end

  post_install do |installer|
    react_native_post_install(installer)
    __apply_Xcode_12_5_M1_post_install_workaround(installer)
  end

  post_integrate do |installer|

环境版本信息 #

• node: 14.21.2
• React: 17.0.2
• React Native: 0.68.2
• Xcode: 12.1

已尝试无效方案 #

• 多次重装Node Modules和Pods
• 移除use_frameworks!或use_modular_headers!配置
• 在Podfile中添加glog依赖

针对性解决方案 #

1. 彻底清理Xcode缓存 #

执行以下命令清理DerivedData和项目构建缓存：

rm -rf ~/Library/Developer/Xcode/DerivedData
xcodebuild clean -project ios/weedlemobiledapptraining.xcodeproj -scheme weedlemobiledapptraining -configuration Debug

2. 重置Swift Package缓存 #

打开Xcode操作步骤：
File > Packages > Reset Package Caches
等待缓存重置完成后，重新尝试构建。

3. 适配Xcode版本调整Pod脚本 #

Xcode 12.1与React Native 0.68.x的C++编译标准存在兼容性问题，修改Podfile的post_install脚本，强制React-logger使用兼容的编译标准：

post_install do |installer|
  react_native_post_install(installer)
  __apply_Xcode_12_5_M1_post_install_workaround(installer)
  
  # 新增：设置React-logger的C++编译标准
  installer.pods_project.targets.each do |target|
    if target.name == 'React-logger'
      target.build_configurations.each do |config|
        config.build_settings['CLANG_CXX_LANGUAGE_STANDARD'] = 'c++17'
        config.build_settings['CLANG_CXX_LIBRARY'] = 'libc++'
      end
    end
  end
end

4. 重新安装依赖 #

修改Podfile后，重新执行依赖安装：

rm -rf node_modules && npm install
cd ios && pod deintegrate && pod install && cd ..

5. 手动移除冲突的Swift Package缓存 #

如果上述步骤无效，手动删除swift-protobuf的缓存目录：

rm -rf ~/Library/Developer/Xcode/DerivedData/*/SourcePackages/checkouts/swift-protobuf
