Flutter: “ flutter build ios –release -v ” failed and show Command PhaseScriptExecution failed with a nonzero exit code . SOS

Issue

I was using VSCode to archive an ios .ipa. When I tried "flutter build ios –release", it failed with message: " Command PhaseScriptExecution failed with a nonzero exit code". I google this error and found many solutions, but none of them works for me. These solutions refer to "Key Chain Access","delete pods and clean build folder" and so on. I even update my MacOS system and ‘XCode’ to the newest version, but no miracle happens.
Finally I found an useful command "flutter build ios –release -v" to show the detail info, here is the log on VSCode:

It seems like something wrong with my dart SDK, I’ll be appreciate anyone helps me.

PS: This strange error only shows in my own MacBook Pro, it packages smoothly when I run the build command in my company’s MacBook Pro.

Solution

you can try running the command:

flutter clean

rm -rf ios/Flutter/Flutter.framework

flutter build ios --release

OR uninstall flutter’s SDK and try reinstall it again.
