Unbound Variable Command PhaseScriptExecution failed with a nonzero exit code

Viewed 3527

I am new to flutter. The android section build successfully, but the Xcode section is failing to build. Can someone point me to what I need to do? (in VSCode or Xcode). The last things I did were 1) Delete /iOS/Pods, Podfile.lock, Runner.xcworksp. 2) Reinstall Pod (Pod Install), 3) ran Product - Clean Build Folder, but the build process still failed.

Could you provide a flutter doctor --verbose logs? The error "Unbound Variable Command PhaseScriptExecution failed with a nonzero exit code" is thrown by CocoaPods, not directly caused by Flutter SDK. You can try the suggestions posted on this GitHub issue thread https://github.com/CocoaPods/CocoaPods/issues/8035 and see which one may work for you. On my tests, deleting /iOS/Pods, Podfile.lock, Runner.xcworkspace gets regenerated after flutter run.

For reference, here's my flutter doctor logs
