【问题描述】：
我几个月来一直在开发一个应用程序并使用 Flutter，但是每当我升级 Flutter 时，都会感到非常痛苦，因为我必须努力尝试让它再次构建。通常手动清理 CocoaPods 和 pubspec.yaml 就足够了，但这次没有。
我已将我的 Flutter 版本从 1.10.7 升级到 1.14.6，对我的 pods 进行了核对和 pubspec.yaml，核对了我的 Flutter 安装、我的存储库，但没有任何效果。
关于它的另一个奇怪的事情是，我在不同机器上的同一分支上使用相同版本的颤振、飞镖、cocoapods 和 ruby 构建运行良好。是否有一些东西缓存在我没有正确清理的地方？当我尝试构建时，它说它失败并出现错误，但不幸的是日志输出实际上并没有显示任何错误，而只显示警告。这是我的日志输出的一部分：
8 warnings generated.

任何帮助都将不胜感激，因为我已经用尽了关于可能导致此错误的想法。

尝试使用
-v选项构建以获得详细日志：flutter run -v -
** BUILD FAILED ** The following build commands failed: PhaseScriptExecution Run\ Script /Users/hallo/Library/Developer/Xcode/DerivedData/Runner-hkmupomiwzgwwybgvjflbqilwoeu/Build/Intermediates.noindex/Runner.build/Debug-iphonesimulator/Runner.build/Script-BC68FF6F226F5DF100E3C5D3.sh (1 failure) -
我用 flutter run -v 得到了这个
-
如果从 Xcode 内部运行会发生什么？
