【问题描述】：

我已经成功构建了一个 android 应用程序，现在我正在使用 Flutter 构建 ios 应用程序。这是第一次的所有文件但是重新启动我的vscode后我收到了这个错误。谁能帮我解决以下问题？我在下面包含了 Pod 文件代码和调试输出。

#platform :ios, '9.0'


ENV['COCOAPODS_DISABLE_STATS'] = 'true'

project 'Runner', 
  'Debug' => :debug,
  'Profile' => :release,
  'Release' => :release,


def flutter_root
  generated_xcode_build_settings_path = File.expand_path(File.join('..', 'Flutter', 'Generated.xcconfig'), __FILE__)
  unless File.exist?(generated_xcode_build_settings_path)
    raise "#generated_xcode_build_settings_path must exist. If you're running pod install manually, make sure flutter pub get is executed first"
  end

  File.foreach(generated_xcode_build_settings_path) do |line|
    matches = line.match(/FLUTTER_ROOT\=(.*)/)
    return matches[1].strip if matches
  end
  raise "FLUTTER_ROOT not found in #generated_xcode_build_settings_path. Try deleting Generated.xcconfig, then run flutter pub get"
end

require File.expand_path(File.join('packages', 'flutter_tools', 'bin', 'podhelper'), flutter_root)

flutter_ios_podfile_setup

target 'Runner' do
  use_frameworks!
  use_modular_headers!

  flutter_install_all_ios_pods File.dirname(File.realpath(__FILE__))
end

post_install do |installer|
  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)
  end
end

【问题讨论】：

这是构建的完整输出？

@fartem 很抱歉没有提供完整的调试代码。现已编辑。

【参考方案1】：

根据错误消息，您的 Podfile 中缺少 platform 属性。 要修复它，请编辑您应用的 Podfile，并添加以下行： platform :ios, '10.0' 您也可以定义不同的 iOS 版本。

【参考方案2】：

试试这个

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
