React Native 0.70.6添加相机权限后出现x86_64架构重复符号错误

项目原本运行正常，在通过react-native-permissions添加相机权限的Pod配置后，编译时触发duplicate symbols for architecture x86_64错误。已尝试删除Pods重新生成、删除DerivedData文件夹，问题仍未解决。

当前Podfile内容 #

require_relative '../node_modules/react-native/scripts/react_native_pods'
require_relative '../node_modules/@react-native-community/cli-platform-ios/native_modules'

platform :ios, '12.4'
install! 'cocoapods', :deterministic_uuids => false

target 'JDB_App' do
  config = use_native_modules!

  # Flags change depending on the env values.
  flags = get_default_flags()
  pod 'Firebase', :modular_headers => true
  pod 'FirebaseCore', :modular_headers => true
  pod 'GoogleUtilities', :modular_headers => true
  $RNFirebaseAsStaticFramework = true
  permissions_path = '../node_modules/react-native-permissions/ios'
  pod 'Permission-Camera', :path => "#{permissions_path}/Camera"

  use_react_native!(
    :path => config[:reactNativePath],
    # Hermes is now enabled by default. Disable by setting this flag to false.
    # Upcoming versions of React Native may rely on get_default_flags(), but
    # we make it explicit here to aid in the React Native upgrade process.
    :hermes_enabled => true,
    :fabric_enabled => flags[:fabric_enabled],
    # Enables Flipper.
    #
    # Note that if you have use_frameworks! enabled, Flipper will not work and
    # you should disable the next line.
    :flipper_configuration => FlipperConfiguration.enabled,
    # An absolute path to your application root.
    :app_path => "#{Pod::Config.instance.installation_root}/.."
  )

  target 'JDB_AppTests' do
    inherit! :complete
    # Pods for testing
  end

  post_install do |installer|
    react_native_post_install(
      installer,
      # Set `mac_catalyst_enabled` to `true` in order to apply patches
      # necessary for Mac Catalyst builds
      :mac_catalyst_enabled => false
    )
    __apply_Xcode_12_5_M1_post_install_workaround(installer)
  end
end

解决方法 #

• 匹配依赖版本：React Native 0.70.6需要对应版本的react-native-permissions，检查package.json中依赖版本是否兼容，必要时调整到适配版本。
• 统一静态库配置：项目中已设置$RNFirebaseAsStaticFramework = true，需确保权限组件也以静态框架形式引入，避免符号冲突：
  方法1：修改相机权限的Pod配置，添加模块化头声明

  pod 'Permission-Camera', :path => "#{permissions_path}/Camera", :modular_headers => true
  

  方法2：在use_native_modules!之前添加全局静态框架配置

  $PermissionsAsStaticFramework = true
  

• 排查重复引入：执行npx react-native unlink react-native-permissions，确认没有通过自动link重复引入Permission-Camera模块，之后重新执行pod install。
• 深度清理编译缓存：
  1. 执行pod deintegrate彻底移除Pods
  2. 删除项目根目录下的Podfile.lock文件
  3. 执行pod install --repo-update更新依赖
  4. 打开Xcode，按Command+Shift+K清理项目，再重新编译
