'How to fix Command PhaseScriptExecution failed with a nonzero exit code on flutter run in macOS?

I am working on a flutter app. I recently shifted to macOS and since then haven't been able to run the app. Other apps are running fine so I think the error is in within the code of this app. And maybe because of this same reason I am unable to make a build.

Here is the output of flutter doctor:

Any help would be great. Thanks for your time.



Solution 1:[1]

Simple Commands that made my archive successful after 2 days of struggle:

flutter clean
flutter pub get
flutter pub upgrade
cd iOS
pod install
pod update 

And the issue is resolved.

Solution 2:[2]

You won't believe it, but in my case the problem was caused by a corrupted image that was used to generate the launcher icons. Something with the alpha channel was messed up. After I fixed it, the product could be archived successfully.

Solution 3:[3]

In the migration try replacing the podfile with this:

https://github.com/jmagman/flutter/blob/40b21e52153e1246120e90d1c757c0ec4c34ebb0/dev/integration_tests/flutter_driver_screenshot_test/ios/Podfile

Steps:

  1. Remove PodFile.lock
  2. Replace Podfile
  3. flutter clean
  4. flutter pub get
  5. cd ios /
  6. pod install
  7. pod update
  8. relaunch

Now apparently it is an error generated by the automatic processes of the 1.20 of the flutter SDK. In my case, I removed all the plugins from my project and started placing them one by one.

In my project the error appeared because I had the plugin flutter_dotenv 2.1.0 and the .env files corrupt the automatic flutter process.

Solution 4:[4]

  1. Delete podfile.lock
  2. Ios>pod install
  3. flutter clean
  4. flutter run

Solution 5:[5]

Sometimes happen when you have this import 'dart:html'; and run the app in IOS.

Solution 6:[6]

  1. Delete Run Binary from Build Phases.
  2. Delete Thin Binary from Build Phases.

Solution 7:[7]

For me this error occurred because of low disc space. as I cleaned some of files and it worked

Solution 8:[8]

Check your image assets!

I spent days on this, upgraded flutter, upgraded Xcode, re-installed Xcode command line tools, and did every conceivable combination of flutter clean, flutter pub upgrade, pod install etc. I even used flutter create to regenerate the ios folder.

I searched for responses related to Requested but did not find extension point with identifier Xcode.IDEKit.ExtensionSentinelHostApplications for extension Xcode.DebuggerFoundation.AppExtensionHosts.watchOS of plug-in com.apple.dt.IDEWatchSupportCore because that was part of the Xcode error output, but in the end it was none of that.

I had recently added a new .png asset to my project and that was the problem. I converted it to .jpeg and the problem disappeared.

Solution 9:[9]

The only thing that worked for me was to backup my project and clone a fresh copy from the repository. I suspect it was an issue with one of the hidden files or folders like .symlinks or Pods.
