如果我使用这个方法，

\n

post_install do |installer|\n  installer.pods_project.targets.each do |target|\n    target.build_configurations.each do |config|\n      if Gem::Version.new(\'8.0\') > Gem::Version.new(config.build_settings[\'IPHONEOS_DEPLOYMENT_TARGET\'])\n        config.build_settings[\'IPHONEOS_DEPLOYMENT_TARGET\'] = \'8.0\'\n      end\n    end\n  end\nend\n

\n

我会收到这个错误...

Answer 1

就我而言，我在尝试清理 258go macbook 上的一些存储以更新 Xcode 时删除 flutter 实例后遇到此错误:(，这样做时我可能删除了 flutter.framework。

这里给出的解决方案对我来说没有任何改变。

所以我尝试清理 pod 中的所有内容，包括缓存。pod install命令失败，因为缺少ios工具，可以通过flutter precache --ios下载。

所以为我解决这个问题的完整过程是：

cd ios
pod cache clean --all
rm -rf ~/Library/Caches/CocoaPods
rm -rf Pods
rm -rf ~/Library/Developer/Xcode/DerivedData/*
pod deintegrate
flutter precache --ios
pod install

我希望这个解决方案能够帮助某人并防止他们像我一样失去一整天的工作。

Answer 2

对于这个错误我已经尝试了很多解决方案。唯一可能的解决方案是删除 FLUTTER PATH 中的 flutter 文件夹，然后重新复制 flutter 文件夹。

这解决了我的错误。
