React Native 0.75.4执行pod install失败：Podfile报错undefined method `[]' for nil

报错指向config = use_native_modules!这行，说明use_native_modules!返回了nil，后续调用config[:reactNativePath]触发了方法不存在的错误。根源在于你的Podfile存在两处关键配置冲突：

• 重复调用use_frameworks!导致CocoaPods配置状态异常
• 重复加载react-native/scripts/react_native_pods.rb引发方法冲突

修复步骤 #

1. 合并use_frameworks!配置 #

删除重复的use_frameworks!调用，统一配置静态框架：

# 替换原来的两段use_frameworks!代码
linkage = ENV['USE_FRAMEWORKS'] || 'static'
Pod::UI.puts "Configuring Pod with #{linkage}ally linked Frameworks".green
use_frameworks! :linkage => linkage.to_sym
$RNFirebaseAsStaticFramework = true

2. 移除重复的react_native_pods.rb加载 #

Podfile顶部已经通过require加载了该脚本，删除target内部的node_require('react-native/scripts/react_native_pods.rb')调用。

3. （可选）显式指定react-native路径 #

如果上述修改后仍有问题，可以给use_native_modules!添加路径参数：

config = use_native_modules!(:path => "../node_modules/react-native")

修改后的完整Podfile示例 #

# Resolve react_native_pods.rb with node to allow for hoisting
require Pod::Executable.execute_command('node', ['-p',
  'require.resolve(
    "react-native/scripts/react_native_pods.rb",
    {paths: [process.argv[1]]},
  )', __dir__]).strip

platform :ios, '13.4'
prepare_react_native_project!

# 合并use_frameworks!配置，避免重复调用
linkage = ENV['USE_FRAMEWORKS'] || 'static'
Pod::UI.puts "Configuring Pod with #{linkage}ally linked Frameworks".green
use_frameworks! :linkage => linkage.to_sym
$RNFirebaseAsStaticFramework = true

ENV['USE_HERMES'] = '0'

target 'project' do
  project 'project.xcodeproj'
  config = use_native_modules!

  use_react_native!(
    :path => config[:reactNativePath],
    # Fabric is not compatible with use_frameworks as per react-native-firebase doc
    :fabric_enabled => false,
    # An absolute path to your application root.
    :app_path => "#{Pod::Config.instance.installation_root}/.."
  )

  def node_require(script)
    # Resolve script with node to allow for hoisting
    require Pod::Executable.execute_command('node', ['-p',
      "require.resolve(
        '#{script}',
        {paths: [process.argv[1]]},
      )", __dir__]).strip
  end

  node_require('react-native-permissions/scripts/setup.rb')

  # ⬇️ uncomment wanted permissions
  setup_permissions([
    # 'AppTrackingTransparency',
    # 'Bluetooth',
    # 'Calendars',
    # 'CalendarsWriteOnly',
    'Camera',
    # 'Contacts',
    # 'FaceID',
    # 'LocationAccuracy',
    # 'LocationAlways',
    'LocationWhenInUse',
    # 'MediaLibrary',
    # 'Microphone',
    # 'Motion',
    'Notifications',
    # 'PhotoLibrary',
    # 'PhotoLibraryAddOnly',
    # 'Reminders',
    # 'Siri',
    # 'SpeechRecognition',
    # 'StoreKit',
  ])

  pod 'RNSecureStorage', :path => '../node_modules/rn-secure-storage/ios/RNSecureStorage.podspec'

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

  post_install do |installer|
    react_native_post_install(
          installer,
          config[:reactNativePath],
          :mac_catalyst_enabled => false,
          # :ccache_enabled => true
    )
  end
end

最后执行清理和重装 #

# 清理现有Pods和缓存
rm -rf Pods Podfile.lock
pod cache clean --all
# 重新安装
pod install
