rails: 7.1.0 version causing the issue undefined method `deprecator' for ActiveSupport:Module (NoMethodError)

gem uninstall -v “7.1.0” gem install -v “7.0.8”

this is just a workaround until the cocoapod team fix the issue

You also need to add require "active_support" before that. See https://guides.rubyonrails.org/active_support_core_extensions.html#cherry-picking-a-definition

So the problem is this line https://github.com/CocoaPods/CocoaPods/blob/479e71131962e3e560e4cc0601d39860c2a590ce/lib/cocoapods.rb#L9 requires a file, which then executes https://github.com/rails/rails/blob/2d271a4b901e7a7dae8ba4e5e83edfebdee278e8/activesupport/lib/active_support/core_ext/array/conversions.rb#L108, but deprecator is defined in https://github.com/rails/rails/blob/main/activesupport/lib/active_support/deprecator.rb which is required by https://github.com/rails/rails/blob/2d271a4b901e7a7dae8ba4e5e83edfebdee278e8/activesupport/lib/active_support.rb#L29

So, I think the solution is to add require "active_support" right before these lines https://github.com/CocoaPods/CocoaPods/blob/479e71131962e3e560e4cc0601d39860c2a590ce/lib/cocoapods.rb#L7-L9 in the cocoapods itself.

Looks like it is fixed by https://github.com/CocoaPods/CocoaPods/pull/12082

If you are not in a Rails application (that already does that for you automatically), you should always require active_support beforing requiring anything else inside active_support. This is a requirement from the framework since the beginning.

See https://guides.rubyonrails.org/active_support_core_extensions.html#stand-alone-active-support

This is an issue in CocoaPods, or any gems that requires Active Support features before requiring the active_support entrypoint.

This broke a lot of things for us in many projects. Gems were hit particularly bad since they do not have a Gemfile.lock. Are you guys going to fix this or shall we go through all the projects adding require 'active_support' wherever we want to use one of the Active Support features?

@fatkodima I just started seeing this on our CI, for some reason it still works locally. After gem install cocoapods we can no longer install with pod install

Hello,

When I try the workaround I receive the following error. Could you please help me?:

In my case I have version 7.1.1:

gem list | grep -i active activesupport (7.1.1)

sudo gem uninstall -v “7.1.1” ERROR: While executing gem … (Gem::Requirement::BadRequirementError) Illformed requirement [““7.1.1””]

I am seeing this exception not while using cocoapods, but rather simply from requiring active_support/testing/time_helpers (which I do in my spec_helper.rb for a project using RSpec).

Here’s a very simple reproduction:

require 'bundler/inline'

gemfile(true) do
  source 'https://rubygems.org'
  gem 'activesupport', '7.1.0'
end

require 'active_support/testing/time_helpers'

Result:

Downgrading the active support to 7.0.8 worked
