flutter - 尝试为 iOS 运行或构建 Flutter 项目时出错

Question

所以基本上我可以运行其他项目，我可以为 Android 运行这个项目，但是当我想运行它或为 iOS 构建它时，我收到以下错误消息。这也不是与项目相关的问题，我的同事可以很好地运行它。我尝试了所有可能的在线解决方案，将安装后的内容添加到 Podfile，尝试在 Xcode 中更改为“旧版构建系统”，但出现相同错误，尝试重新安装 Pod、CocoaPods，甚至切换到测试版。不知道该怎么办了。

相关 Flutter project - XCode build failed
首先验证你在flutter channel中是否稳定，然后flutter upgrade
然后，什么对我有用:

sudo gem uninstall cocoapods; 
sudo gem install cocoapods; 
flutter clean
flutter pub get
cd ios; pod install; cd ..;

其他可能有帮助的命令

cd ios; pod install --repo-update; cd ..;
//deactivate rvm
rvm use system

其他想法:

删除整个 repo 和 git clone

删除派生数据(检查谷歌)

删除 Podspec.lock 和 Gemfile.lock
