所以基本上我可以运行其他项目，并且可以为Android运行该项目，但是当我想为iOS运行或构建它时，会收到以下错误消息。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中，尝试在Xcode中更改为“旧版构建系统”，但存在相同的错误，尝试重新安装Pod，CocoaPods，甚至切换到Beta版。不知道该怎么办。

Could not build the application for the simulator.
Error launching application on iPhone 11 Pro Max.
答案 0 :(得分：0)
与Flutter project - XCode build failed有关
首先确认你在flutter channel中是稳定的，然后flutter升级
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 ..;
其他可能有用的命令
cd ios; pod install --repo-update; cd ..;
//deactivate rvm
rvm use system
