ios - 未绑定(bind)变量命令 PhaseScriptExecution 失败，退出代码非零

Question

我是新来的。 android 部分构建成功，但 Xcode 部分构建失败。有人可以指出我需要做什么吗？ (在 VSCode 或 Xcode 中)。我做的最后一件事是 1) 删除/iOS/Pods、Podfile.lock、Runner.xcworksp。 2)重新安装Pod(Pod Install)，3)运行Product - Clean Build Folder，但构建过程仍然失败。

你能提供一个flutter doctor --verbose日志？ CocoaPods 抛出“Unbound Variable Command PhaseScriptExecution failed with a nonzero exit code”错误，不是由 Flutter SDK 直接引起的。您可以尝试发布在此 GitHub 问题线程 https://github.com/CocoaPods/CocoaPods/issues/8035 上的建议看看哪一个适合你。在我的测试中，删除/iOS/Pods、Podfile.lock、Runner.xcworkspace 会在 flutter run 之后重新生成.
