Question

我试图归档并构建抖动的IOS项目，以便最终生成IPA，但由于此错误而苦苦挣扎，我试图遵循有关similar问题的现有问题，明白了：

Command PhaseScriptExecution failed with a nonzero exit code

此问题可能是什么原因？

Answer 1

我的情况就是这样，我使用了websafe_svg 1.1.0，它取决于flutter_svg ^0.17.4。根据 @Lutaaya Huzaifah Idris 的建议，此问题已在flutter_svg: ^0.18.0的最新更新中得到解决。

因此，如果您使用websafe_svg，请在pubspec.yaml中添加以下行以解决此问题，

dependency_overrides:
  flutter_svg: ^0.18.0

Answer 2

我所做的是将flutter_svg软件包降级为 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，很可能是您包装上的问题。首先运行flutter pub get看看是否可行，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。

Answer 3

我遇到了同样的问题，我只是将Flutter版本降级了。

获取颤振的最新标记版本

git checkout v1.16.3

完成后，转到VS终端并运行Flutter Doctor。让它完成。重新启动VS（编辑器）。您现在可以构建它。
