运行 pod install 时出错 - 在目标“Runner”上自动分配版本为“8.0”的平台“iOS”

Question

你好，我无法用 Cocoapods 解决这个问题，任何人都可以帮助我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：

在调试模式下在 iPhone 11 上启动 lib/main.dart... 运行 pod install... 1,3s CocoaPods' 输出：？准备

CocoaPods 的错误输出：

[!] Automatically assigning platform `iOS` with version `8.0` on target `Runner` because no platform was specified. Please specify a platform for this target in your Podfile. See `https://guides.cocoapods.org/syntax/podfile.html#platform`.

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

Answer 1

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

Answer 2

将 Podfile 设置为包所需的版本即可。

例如，如果您想使用 webview_cookie_manager 2.0.0，则应将 iOS 的最低版本设置为 11.0，如其规范页面上所示。

https://pub.dev/packages/webview_cookie_manager

因此，在 Podfile 上，按如下方式设置平台 ios 值是可行的。

 platform :ios, '11.0'
