如果有人从react native issue来这里，只需删除/build文件夹并输入react-native run ios

对于Flutter使用这个

platform :ios, '10.0'

post_install do |installer|
  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)
  end
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings.delete 'IPHONEOS_DEPLOYMENT_TARGET'
    end
  end
end

您可以设置您的podfile自动匹配所有podfile的部署目标到您当前的项目部署目标，如下所示:

post_install do |installer|
 installer.pods_project.targets.each do |target|
  target.build_configurations.each do |config|
   config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '9.0'
  end
 end
end

无需在pod安装后指定部署目标，您可以为每个pod删除pod部署目标，这将导致部署目标从Podfile继承。

您可能需要运行pod install以使效果发生。

platform :ios, '12.0'

  post_install do |installer|
    installer.pods_project.targets.each do |target|
      target.build_configurations.each do |config|
        config.build_settings.delete 'IPHONEOS_DEPLOYMENT_TARGET'
      end
    end
  end

对我有用:

rm ios/Podfile
flutter pub upgrade
flutter pub get
cd ios && pod update
flutter clean && flutter run
sudo arch -x86_64 gem install ffi
arch -x86_64 pod install 

试试下面这些步骤:

删除Podfile.lock 删除你的Podfile 建设项目 从firebase添加初始化代码 cd / ios 圆荚体安装 运行项目

这对我来说很管用。
