你好，我无法用 Cocoapods 解决这个问题，任何人都可以帮助我，这是我第一次使用这个 import-import 'package:flutter_vlc_player/flutter_vlc_player.Dart'; 而不是什么可能是错的。

（我在mac上使用android studio）

错误：

在 iPhone 11 上以调试模式启动 lib/main.dart... 运行 pod install... 1,3s CocoaPods 的输出： ↳ 准备中

运行 pod install 时出错在 iPhone 11 上启动应用程序时出错。

【问题讨论】：

【参考方案1】：

打开 [YourProject]/ios/Podfile 并从 platform :ios, '9.0' 中删除 # 符号，然后尝试 flutter run。如果它不起作用，请将版本号例如增加到 10.0

【讨论】：

【参考方案2】：

将 Podfile 设置为包所需的版本会起作用。

例如，如果您想使用 webview_cookie_manager 2.0.0，您应该将 iOS 的最低版本设置为 11.0，如其规范页面上给出的那样。

https://pub.dev/packages/webview_cookie_manager

所以在 Podfile 上，设置平台 ios 值如下所示。
