Flutter pod: An error occurred while processing the post-install hook of the Podfile

Question

The problem is that when I run a flutter app after having installed a plugin (firebase_core in this case) I get an error:

An error occurred while processing the post-install hook of the Podfile.

undefined local variable or method `continue' for #<Pod::Podfile:0x00000001099e67b8 @defined_in_file=#Pathname:/Volumes/Coding-IT/Coding/Projects/flutter_37hours/ios/Podfile, @internal_hash={}, @root_target_definitions=[#<Pod::Podfile::TargetDefinition label=Pods>], @current_target_definition=#<Pod::Podfile::TargetDefinition label=Pods>, @post_install_callback=#<Proc:0x0000000109a07e40 /Volumes/Coding-IT/Coding/Projects/flutter_37hours/ios/Podfile:37>, @installation_options=#<Pod::Installer::InstallationOptions:0x0000000109ab6eb8 @clean=true, @deduplicate_targets=true, @deterministic_uuids=true, @integrate_targets=true, @lock_pod_sources=true, @warn_for_multiple_pod_sources=true, @warn_for_unused_master_specs_repo=true, @share_schemes_for_development_pods=false, @disable_input_output_paths=false, @preserve_pod_file_structure=false, @generate_multiple_pod_projects=false, @incremental_installation=false, @skip_pods_project_generation=false>>

  continue if xcframework_file.start_with?(".") # Hidden file, possibly on external disk.

The problem appears to be with the continue word, but I don't know exactly why this is happening and how to solve the problem :( I've tried reinstalling cocoapods multiple times, from homebrew and from rubygems, I tried flutter clean, I tried reinstalling ruby and changing versions. No luck. Hope someone can help me, thanks

Answer 1

I'm looking into this too. It seems to be related to this issue: https://github.com/flutter/flutter/issues/104118

But it's closed the fix seems to be merged with flutter master branch. Idk! Might need to wait for next flutter update.

edit - I just tried this on beta channel and pod install completed. So you can wait till it's on stable or switch channels to run iOS. Cheers!

Incase anyone is facing this same issue,

1. Check ruby installation (use above ruby 3.1.3p185)
2. Check coco-pads (10.1.2 above)
3. Delete and Redownload your entire flutter sdk

move to iOS folder, run flutter pre cache, then pod install

For ruby >> brew install rbenv 3.1.3 (or use any version you want)

which ruby >>> (To confirm installation path on mac /usr/local/var/rbenv/shims/ruby)

sudo gem install bundler >>> (needed for cocopoads)

For cocopoads>>

sudo gem uninstall cocoapods
sudo gem uninstall cocoapods-core
sudo gem uninstall cocoapods-deintegrate
sudo gem uninstall cocoapods-downloader
sudo gem uninstall cocoapods-plugins
sudo gem uninstall cocoapods-search
sudo gem uninstall cocoapods-trunk
sudo gem uninstall cocoapods-try
sudo gem install cocoapods -v 1.10.3
sudo gem install cocoapods -v 1.11.3

Delete Flutter SDK, and redownload to the same path it existed before.

Then on your project, move to your ios folder and run

flutter precache --ios
cd ../ (to move back)
flutter pub get
cd ios
pod install --verbose
