Command phasescriptexecution failed with a nonzero exit code flutter

Problem :

I am trying to add flutter to the existing app. So before doing on the production app I tried with brand new Xcode 10 Single View Application. I followed the tutorial here on https://github.com/flutter/flutter/wiki/Add-Flutter-to-existing-apps and got stuck after adding the run script in the build phase of my target. It's giving the error:

Error:

Command PhaseScriptExecution failed with a nonzero exit code

I have tried below things.

My pod file:

# Uncomment the next line to define a global platform for your project
platform :ios, '10.0'

target 'AFEiOS' do
  # Comment the next line if you don't want to use dynamic frameworks
  use_frameworks!

  # Pods for AFEiOS

  target 'AFEiOSTests' do
    inherit! :search_paths
    # Pods for testing
  end

  target 'AFEiOSUITests' do
    inherit! :search_paths
    # Pods for testing
  end

    flutter_application_path = '/Users/dhavalkansara/FlutterToNative/AFE_flutter/'
    eval(File.read(File.join(flutter_application_path, '.ios', 'Flutter', 'podhelper.rb')), binding)


end

• Already added FLUTTER_ROOT in my project.

Please help me out with this issue.

Answer 1:

This work for me Thanks Alexander Lozano, I upload image for Xcode Version 12.0.1

Answer 2:

this works for me: xcode 11.3.1

xcode ->targets->runner

in build phases: run script and thin binary, select: run script only when installing

Answer 3:

For beginners: (tested on XCODE 12.0.1) open Xcode--> Open a project or file --> go to the flutter app path/ios directory--> open --> Runner and follow attached image steps

Answer 4:

I was having the issue for 2 days.

My failure was slightly different:

Failed to package /path/to/my/app.
Command PhaseScriptExecution failed with a nonzero exit code
note: Using new build system
note: Planning
note: Build preparation complete
note: Building targets in parallel

I was on Flutter 2.5.1, I tried all of the suggestions found here (amongst others I googled). I wish I knew the answer or understood why, but a simple

`flutter upgrade` 

Worked for me (I ended up with 2.5.3)

Answer 5:

This worked for me:
1) Add this to your podfile:

flutter_application_path = '/Users/dhavalkansara/FlutterToNative/AFE_flutter/'
    eval(File.read(File.join(flutter_application_path, '.ios', 'Flutter', 'podhelper.rb')), binding)

    install_all_flutter_pods(flutter_application_path)

PS. You may also need to do that for each target, i.e

target 'AFEiOSTests' do
    inherit! :search_paths
    install_all_flutter_pods(flutter_application_path)
    # Pods for testing
  end

  target 'AFEiOSUITests' do
    inherit! :search_paths
    install_all_flutter_pods(flutter_application_path)
    # Pods for testing
  end

2) Run pod install
