無法在模擬器中運行 flutter 應用程序 (iOS 15)

Question

我已將 flutter 版本從 1.x 更新到 2.8.x，現在我正在嘗試在 Xcode 13.1 和模擬器 iOS 15 中運行應用程序。我正面臨此錯誤。 'mobileffmpeg/LogDelegate.h' file not found並且Command CompileSwiftSources failed with a nonzero exit code我嘗試了一些可用的解決方案，但它對我不起作用。

我正在使用最新的 cocoa pod 版本1.11.3

錯誤日志（在 iOS 中執行 flutter clean 和 flutter pub get 和 pod install 之后）

Answer 1

當您升級 flutter 版本時，一些庫將無法再工作。 你知道^的意思了嗎？ 例如：您在 5.10 版中使用 lib abc，就像這樣abc: ^5.1.0並且 abc 有其他版本5.2.0 ，... 5.9.0和6.0.0 。 如果你使用^那意味着版本范圍是從5.1.0 to 5.9.0 。 也許它在版本 5.9.0 中有問題。 此外，有時原因不是您的庫而是它的依賴項。 abc庫在內部使用xyz然后它使用與您的 flutter 版本沖突的更高版本。

• 所以這里的解決方案是：
  • 嘗試修復所有庫的硬版本，刪除使用^ : abc: 5.1.0
  • 如果問題來自您的庫的依賴性，例如xyz 。 從pubspec.lock檢查你的xyz版本，然后將更多 package xyz添加到具有兼容版本的 pubspec.yaml 中。

更新：您似乎對 package https://pub.dev/packages/flutter_ffmpeg有疑問，請查看 label 部分的自述文件：

2.1.2 iOS (Flutter >= 2.x) then replace two lines below:

def flutter_install_ios_plugin_pods(ios_application_path = nil)
↓
def flutter_install_plugin_pods(application_path = nil, relative_symlink_dir, platform)

plugin_pods = flutter_parse_plugins_file(plugins_file)
↓
plugin_pods = flutter_parse_plugins_file(plugins_file, platform)

而且，因為package停產了。 您應該更改為https://pub.dev/packages/ffmpeg_kit_flutter
