Flutter - 命令 PhaseScriptExecution 失败，退出代码非零

Question

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，我尝试遵循有关我无法解决的类似问题的现有问题：

Command PhaseScriptExecution failed with a nonzero exit code

导致此问题的原因是什么？

Answer 1

我的情况是这样的，我使用了websafe_svg 1.1.0这取决于flutter_svg ^0.17.4。并且正如@Lutaaya Huzaifah Idris所建议的，此问题已在flutter_svg: ^0.18.0.

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

dependency_overrides:
  flutter_svg: ^0.18.0

Answer 2

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

我认为对于颤动的情况，当发生此错误时，很可能是您的软件包出现问题。首先运行flutter pub get看看是否有效，或者尝试一下flutter clean。如果所有包都运行良好，那么您在 IOS 中的构建就会通过。
