Flutter 不会编译我的应用程序的发布版本？

Question

在使用这个应用程序之后，我尝试使用flutter run --release命令将我的应用程序构建到 iOS。 但每当我这样做时，我都会收到此错误*Could not build the precompiled application for the device.*

我试过flutter clean然后flutter upgrade 。 我已经切换了 flutter 分支机构。 我对这个很迷茫！

这是终端 output：

Answer 2

我终于找到了解决办法！

问题最终是 CocoaPod 没有正确安装。

在挖掘了一生的感觉之后，我再次安装了 HomeBrew，然后使用brew install cocoapods命令重新安装了 cocoapod。 之后我运行flutter clean然后flutter run并且它签署了应用程序并在我的 iPhone 上启动它！

感谢您的想法并帮助我解决这个问题！
