Flutter ios 构建失败。模拟器构建也失败

Question

几个月来我一直在开发一个应用程序并使用 Flutter，但是每当我升级 Flutter 时，它是一个巨大的痛苦，因为我必须努力让它重新建立起来。平时手动清理CocoaPods和pubspec.yaml就够了，这次不行。

我已将我的 Flutter 版本从 1.10.7 升级到 1.14.6 , 破坏了我的 pods 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，我的构建运行与相同版本的 flutter、dart、cocoapods 和 ruby 在同一分支上不同的机器。是否有缓存的东西我没有正确清理？当我尝试构建时，它说它因错误而失败，但不幸的是，日志输出实际上并未显示任何错误，仅显示警告。这是我的日志输出的一部分：

任何帮助将不胜感激，因为我已经用尽了所有可能导致此错误的想法。

Answer 1

你运行在 Android 工作室吗？ VS代码？你能 post 你的 flutter doctor -v 吗？

除此之外，所有这些错误都来自 google_sign_in。会推荐以下内容：

删除 google_sign_in（并评论使用此依赖项的任何屏幕）
确保您遵循 iOS Folder
使用不同的库。 google_sign_in 可能未与所有最新的 Flutter 更改同步。

如果您的代码在没有该库的情况下运行，它会清楚地显示最新升级更改的错误。

Answer 2

我通过更改各种内容解决了这个问题。当我进行 flutter 升级时，它通过添加此行

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"; 这导致了很多错误。我删除了这一行，将 Xcode 中的构建系统更改为默认值（这是遗留的），然后在 Xcode 中的嵌入框架中，我删除了 Flutter.framework。

Answer 3

只是运行 flutter clean 在你的项目上，它对我有用。
