我正在尝试存档和构建 Flutter IOS 项目，以便最终生成 IPA，但由于此错误而苦苦挣扎，我尝试关注有关 similar 问题的现有问题我无法得到它：

Command PhaseScriptExecution failed with a nonzero exit code

这个问题的原因可能是什么？

【问题讨论】：

同样的问题，很奇怪。

标签： ios xcode flutter

【解决方案1】：

我的情况是这样的，我使用了websafe_svg 1.1.0，它依赖于flutter_svg ^0.17.4。正如 @Lutaaya Huzaifah Idris 所建议的，此问题已在 flutter_svg: ^0.18.0 的最新更新中得到修复。

因此，如果您使用websafe_svg，则在pubspec.yaml 中添加以下行来解决此问题，

dependency_overrides:
  flutter_svg: ^0.18.0

【解决方案2】：

我所做的是将我的 flutter_svg 包降级为 flutter_svg: ^0.17.4，然后构建通过了。

我认为对于颤振的情况，当发生此错误时，很可能是您的软件包有问题。首先运行flutter pub get 看看它是否有效，或者尝试flutter clean。如果所有软件包都运行良好，那么您在 IOS 中的构建将通过。

【讨论】：

解决了我的问题！

【解决方案3】：

我也遇到了同样的问题，我只是降级我的颤振版本适合我。

从(https://github.com/flutter/flutter)、Clickhere to see attached image获取最新的标签版本的flutter

进入你的flutter目录并运行

git checkout v1.16.3

完成后，转到您的 VS 终端并运行颤振医生。让它完成。重新启动您的 VS（编辑器）。您现在可以构建它。
