Invalid Podfile file specifying multiple post_install hooks is unsupported

Question

I'm using cocoapods 1.1.1 and in my podfile I have more than one post_install hooks. And I'm getting this error :

[!] Invalid `Podfile` file: [!] Specifying multiple `post_install` hooks is unsupported..
-------------------------------------------
 #
 >  post_install do |installer|
 #      installer.pods_project.targets.each do |target|

Did anyone face the same problem before? And Yes! I have 1 post_install in my 1 target and another in global scope. I could move in one, but why?

Answer 1

Solution 2023

When I removed my code from my main target and moved in global scope's post_install block it's works like charm.

For some reason if you add multiple post_install (global and 1 target for instance) move them in same global block and add if-else statements for managing targets.

Answer 2

Move all of them to one place like this, it worked for me.

post_install do |installer|
  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)
  end
end

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
     if config.build_settings['WRAPPER_EXTENSION'] == 'bundle'
     config.build_settings['DEVELOPMENT_TEAM'] = 'S09DP9UN6F'
   end
  end
 end
end

after

post_install do |installer|
  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)
  end
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      if config.build_settings['WRAPPER_EXTENSION'] == 'bundle'
        config.build_settings['DEVELOPMENT_TEAM'] = 'S09DP9UN6F'
      end
    end
  end
end

I temporarily solved this conflict. Put the code in your Podfile.

def multiple_post_install(flutter_application_path)
  #read podhelper from flutter_application_path
  flutter_podhelper = File.read(File.join(flutter_application_path, '.ios', 'Flutter', 'podhelper.rb'))

  #find the post_install end location by hardcoding
  post_install_string = 'post_install do |installer|'
  location = flutter_podhelper.index(post_install_string)
  location += post_install_string.length

  #declare your own hook func
  update_configs_func = %q[
  update_configs(installer)]

  #insert the func you declare
  flutter_podhelper.insert(location, update_configs_func)
  return flutter_podhelper
end

flutter_application_path = 'path/to/my_flutter/'
flutter_podhelper = multiple_post_install(flutter_application_path)
eval(flutter_podhelper, binding)

def update_configs(installer)
  #put your own custom code
end

def main_pods
pod 'CocoaLumberjack', '2.0.0'
pod 'MBProgressHUD', '0.9.1'

post_install do |installer_representation|
    installer_representation.pods_project.targets.each do |target|

        if target.name == 'Pods-AFNetworking'
            target.build_configurations.each do |config|
                config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= ['$(inherited)']
                config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] << '_AFNETWORKING_ALLOW_INVALID_SSL_CERTIFICATES_=1'
            end
        end

    end
end

Please try to remove post_install block. And try again. And share warnings after "pod install" – Nabob

Ok now (as expected) "pod install" works correctly, but compiler now show me some warnings: ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES build setting defined in `Pods/Target Support Files/Pods-TargetName/Pods-TargetName.xcconfig'. This can lead to problems with the CocoaPods installation – Mildredmildrid

I'm glad. Now check your warnings in Xcode, if Xcode has some update for settings, let it update your settings – Nabob

Yep.. now it works correctly and for your info, moving "post_install" out of main block, solved all the problems with GCC_PREPROCESSOR_DEFINITIONS macro in different target. Well done! – Mildredmildrid

I had the Similar Issue , Its Because of the Location Permission Which I added in POD file . then I comment Out this Portion and it works .

# post_install do |installer|
#   installer.pods_project.targets.each do |target|
#     flutter_additional_ios_build_settings(target)
#   end
# end
post_install do |installer|
  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)

    target.build_configurations.each do |config|
      config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= [
        '$(inherited)',

        ## Add this line
         'PERMISSION_LOCATION=1'
      ]
    end
  end
end

  end

  File.foreach(generated_xcode_build_settings_path) do |line|
    matches = line.match(/FLUTTER_ROOT\=(.*)/)
    return matches[1].strip if matches
  end
  raise "FLUTTER_ROOT not found in #{generated_xcode_build_settings_path}. Try deleting Generated.xcconfig, then run flutter pub get"

Please, read the post carefully. This no about abstract_target. – Nabob

Answer 7

I had..

post_install do |installer|
  react_native_post_install(
    installer,
    # Set `mac_catalyst_enabled` to `true` in order to apply patches
    # necessary for Mac Catalyst builds
    :mac_catalyst_enabled => false
  )
  __apply_Xcode_12_5_M1_post_install_workaround(installer)
end

post_install do |installer|
  installer.pods_project.targets.each do |target|
    if target.name == "react-native-quick-sqlite" then
      target.build_configurations.each do |config|
        config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] << 'SQLITE_ENABLE_FTS5=1'
      end
    end
  end
end

and just needed to change it like so..

post_install do |installer|
  react_native_post_install(
    installer,
    # Set `mac_catalyst_enabled` to `true` in order to apply patches
    # necessary for Mac Catalyst builds
    :mac_catalyst_enabled => false
  )
  __apply_Xcode_12_5_M1_post_install_workaround(installer)

  installer.pods_project.targets.each do |target|
    if target.name == "react-native-quick-sqlite" then
      target.build_configurations.each do |config|
        config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] << 'SQLITE_ENABLE_FTS5=1'
      end
    end
  end
end

merging the two blocks with post_install do |installer| into the same block.
