Question

我已经在使用 Flutter 的应用程序上工作了几个月，但是每次升级 Flutter 时，这都是一个巨大的痛苦，因为我必须努力尝试让它重新构建。通常，手动清理 CocoaPods 和 pubspec.yaml 就足够了，但这一次还不够。

我已将 Flutter 版本从 1.10.7 升级到 1.14.6 ，对我的 pods 进行了修改和 pubspec.yaml 破坏了我安装的 Flutter ，我的存储库，但没有任何效果。

另一个奇怪的事情是，我在同一台机器的同一分支上使用相同版本的flutter，dart，cocoapods和ruby运行了正常的构建。我无法正确清理的地方有缓存吗？当我尝试构建时，它说它失败并显示错误，但是不幸的是，日志输出实际上并未显示任何错误，而仅显示警告。这是我的日志输出的一部分：

由于我已尽我所有可能导致此错误的想法，因此将不胜感激。

Answer 1

您是否正在Android Studio上运行？ VS代码？您能发布您的flutter doctor -v吗？

除此之外，所有这些错误均来自google_sign_in。将推荐以下内容：

删除google_sign_in（并使用此依赖项注释所有屏幕）
确保您遵循iOS Folder内的所有正确更改
使用其他库。 google_sign_in可能不是最新的 Flutter 更新。

如果您的代码在没有该库的情况下运行，则显然会显示有关最新升级更改的错误。

Answer 2

我通过更改各种方法解决了该问题。当我执行flutter升级时，它通过添加以下行来更改了我的project.pbxproj文件

shellScript = "# Type a script or drag a script file from your workspace to insert its path.\n\"${PODS_ROOT}/Fabric/run\"\n"; 造成很多错误。我删除了这一行，将Xcode中的构建系统更改为默认值（这是旧系统），然后在Xcode中的嵌入框架中，删除了Flutter.framework。

Answer 3

只需在您的项目上运行flutter clean，它就对我有用。

Flutter ios构建失败。模拟器构建也会失败
