对于flutter，这是我在<project_root>/ios/Podfile中使用的

post_install do |installer|
  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)
  end
  
  installer.pods_project.build_configurations.each do |config|
    config.build_settings["EXCLUDED_ARCHS"] = "armv7"
    config.build_settings.delete 'IPHONEOS_DEPLOYMENT_TARGET'
  end
end

我解决了这个问题，我把build system从New build system改为Legacy build system

在Xcode v10+中，选择文件>项目设置

在之前的Xcode中，选择File > Workspace Settings

将Build System从New Build System更改为Legacy Build System—>单击Done。

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

我在构建React Native项目时也遇到了同样的问题

Cocoapods版本更新对我有效(从1.8.4升级到1.11.2)

我们可以将项目部署目标应用于所有pods目标。 通过在Podfile的末尾添加以下代码块来解决:

post_install do |installer|
  fix_deployment_target(installer)
end

def fix_deployment_target(installer)
  return if !installer
  project = installer.pods_project
  project_deployment_target = project.build_configurations.first.build_settings['IPHONEOS_DEPLOYMENT_TARGET']

  puts "Make sure all pods deployment target is #{project_deployment_target.green}"
  project.targets.each do |target|
    puts "  #{target.name}".blue
    target.build_configurations.each do |config|
      old_target = config.build_settings['IPHONEOS_DEPLOYMENT_TARGET']
      new_target = project_deployment_target
      next if old_target == new_target
      puts "    #{config.name}: #{old_target.yellow} -> #{new_target.green}"
      config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = new_target
    end
  end
end

结果记录:

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。
