React Native iOS执行pod install遇OpenSSL-Universal版本兼容问题求助

背景 #

执行pod install时收到警告：

[!] use_flipper is deprecated, use the flipper_configuration option in the use_react_native function

按照提示修改Podfile，将use_flipper!替换为use_flipper!({ 'Flipper-Folly' => '2.3.0' })，删除Podfile.lock后重新执行pod install，出现以下错误：

[!] CocoaPods could not find compatible versions for pod "OpenSSL-Universal":
  In Podfile:
    Flipper-Folly (= 2.3.0) was resolved to 2.3.0, which depends on
      OpenSSL-Universal (= 1.0.2.20)

    OpenSSL-Universal (= 1.1.1100)

Specs satisfying the `OpenSSL-Universal (= 1.1.1100), OpenSSL-Universal (= 1.0.2.20)` dependency were found, but they required a higher minimum deployment target.

当前iOS部署目标为13.0，调整部署目标后仍无法解决问题，附上当前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, '13.0'
install! 'cocoapods', :deterministic_uuids => false

target 'XXApp' do
  config = use_native_modules!

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

  use_react_native!(
    :path => config[:reactNativePath],
    # to enable hermes on iOS, change `false` to `true` and then install pods
    :hermes_enabled => flags[:hermes_enabled],
    :fabric_enabled => flags[:fabric_enabled],
    # An absolute path to your application root.
    :app_path => "#{Pod::Config.instance.installation_root}/.."
  )

  pod 'react-native-beacons-manager', :path => '../node_modules/react-native-beacons-manager'

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

  # Enables Flipper.
  #
  # Note that if you have use_frameworks! enabled, Flipper will not work and
  # you should disable the next line.
  use_flipper!({ 'Flipper-Folly' => '2.3.0' })

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

方案1：使用官方推荐的flipper_configuration配置 #

根据警告提示，use_flipper已废弃，应在use_react_native!中配置flipper_configuration参数，替代单独调用use_flipper!。修改Podfile如下：

use_react_native!(
  :path => config[:reactNativePath],
  :hermes_enabled => flags[:hermes_enabled],
  :fabric_enabled => flags[:fabric_enabled],
  :app_path => "#{Pod::Config.instance.installation_root}/..",
  # 添加flipper配置
  :flipper_configuration => FlipperConfiguration.enabled(['Flipper-Folly' => '2.3.0'])
)

同时删除原来单独的use_flipper!({ 'Flipper-Folly' => '2.3.0' })行。

方案2：升级Flipper-Folly到兼容版本 #

Flipper-Folly 2.3.0依赖的OpenSSL版本较老，与项目中其他依赖的1.1.1100版本冲突。可以升级Flipper-Folly到更高版本（如2.6.0+，这类版本已适配OpenSSL 1.1.x系列）：

# 对应方案1的配置修改
:flipper_configuration => FlipperConfiguration.enabled(['Flipper-Folly' => '2.6.0'])

# 若暂时保留use_flipper!（不推荐，因已废弃）
use_flipper!({ 'Flipper-Folly' => '2.6.0' })

方案3：强制统一OpenSSL版本 #

如果上述方案无效，可在Podfile的post_install块中添加配置，强制所有依赖使用同一版本的OpenSSL，并适配部署目标：

post_install do |installer|
  react_native_post_install(installer)
  __apply_Xcode_12_5_M1_post_install_workaround(installer)
  
  # 强制OpenSSL-Universal使用1.1.1100版本并适配部署目标
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      if target.name == 'OpenSSL-Universal'
        config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '13.0'
      end
    end
  end
end

通用操作步骤 #

每个方案执行后都需要完成以下步骤：

1. 删除Podfile.lock文件
2. 删除Pods文件夹
3. 执行pod repo update更新本地pod仓库
4. 执行pod install重新安装依赖
