Answer 1

Jimmy Anderson 运行flutter upgrade 后，您需要检查现有项目使用的dependencies 是否也是最新的。

version 1.20.1 出现同样的错误，解决方案是删除 Pods 文件夹，pubspec.lock 文件：

)：完全清除所有指向链接的点：

flutter clean
rm -Rf ios/Pods
rm -Rf ios/.symlinks
rm -Rf ios/Flutter/Flutter.framework
rm -Rf ios/Flutter/Flutter.podspec

)：最后运行这些：

rm ios/Podfile
rm pubspec.lock
flutter run

如果有人有最新的答案，可以完成这个临时解决方案。

Answer 2

这些步骤帮助我解决了类似问题

1. 首先尝试按照以下步骤构建 Android 版本

• 删除pubspec.lock文件
• flutter clean（在你的项目目录中）
• flutter pub get
• flutter build apk --release

然后我看到我的 Android 构建失败，这是一些与依赖相关的问题，我修复了这些问题。然后重复上面的步骤1。之后我的Android构建成功了。

1. 然后尝试按照以下步骤进行 iOS 构建

• 删除了ios目录中的Pods文件夹
• 删除了ios目录下的Podfile.lock文件
• cd ios
• pod install
• pod update
• cd ..
• flutter clean
• flutter pub get
• flutter build ios --release

然后我的 iOS 构建成功了

Answer 3

这些步骤对我有用：

1. 运行flutter build
2. 打开 Xcode (Runner.xcworkspace)
3. 转到产品 -> 清理构建文件夹
4. 在真机上运行
5. 然后再试一次 - flutter build ios
