Ios 如何在React Native中结合Podfile中的后期安装？

我需要在pod文件中添加以下后期安装

post_install do |pi|
  pi.pods_project.targets.each do |t|
    t.build_configurations.each do |config|
      config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '9.0'
    end
  end
end

但是遇到了这个错误

[!] Invalid `Podfile` file: [!] Specifying multiple `post_install` hooks is unsupported..

pod文件中有两个后期安装。我应该如何组合它们来解决错误

post_install do |installer|
    flipper_post_install(installer)
  end
end

post_install do |pi|
  pi.pods_project.targets.each do |t|
    t.build_configurations.each do |config|
      config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '9.0'
    end
  end
end

下面的方法似乎有效

  post_install do |installer|
    flipper_post_install(installer)
    installer.pods_project.targets.each do |t|
      t.build_configurations.each do |config|
        config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '9.0'
      end
    end
  end
