我想把我的Flutter应用发布到App Store，但不幸的是，在Xcode上每次运行构建或归档时，来自Flutter项目的错误 exited with status code 127 会导致 构建被取消。

以下是来自Xcode的错误日志：

解决方案

这终于解决了这个问题 https://stackoverflow.com/a/62381101/9551463

Goto Xcode,
click on Runner
select Project (top one)
go to Info tab
change configurations for debug
top Runner (green icon) to Generated
Bottom Runner (red circles) Pods-Runner-debug
