【问题描述】：

我无法在 ios 模拟器上运行我的应用程序。从 Flutter 2.2.3 升级到 Flutter 2.5.0 后出现此错误

我无法从 android Studio 运行 Flutter 应用。 但如果从 Xcode 打开项目，则应用程序将在 iOS 模拟器中正常运行。

这是错误/警告信息

我尝试了 SO 的几种解决方案，但都没有运气。到目前为止我所尝试的

扑干净 删除 podfile.lock。关注this 在模拟器中删除应用

这是我的 Flutter 医生

[✓] Flutter (Channel stable, 2.5.0, on macOS 11.2.1 20D74 darwin-x64, 语言环境en-ID） [✓] Android 工具链 - 为 Android 设备开发 （Android SDK 版本 31.0.0） [✓] Xcode - 为 iOS 和 macOS 开发 [✓] Chrome - 为网络开发 [✓] Android Studio（版本 2020.3）[✓] VS Code（版本 1.60.0）[✓] 已连接设备（3 个可用）

【参考方案1】：

将此代码添加到您的 Podfile：

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      if config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'].to_f < 9.0
        config.build_settings.delete 'IPHONEOS_DEPLOYMENT_TARGET'
      end
    end
  end
end

您可以将 9.0 更改为项目的部署目标版本。
