Detail

CocoaPods has dependency in activesupport gem

  s.add_runtime_dependency 'activesupport', '>= 4.0.2', '< 5'

And it try to install json v1.8.3. However, it cannot compile it with Ruby 2.4.

Please update activesupport or use json 2.0.0 or higher by adding following dependency

  s.add_runtime_dependency 'json', '>= 2.0.0'

Luckily cocoapods v1.0.1 still works, by running gem install cocoapods -v 1.0.1;
I'm using NativeScript and it requires cocoapods to be installed without specifying a specific version;

Ah this is going to be a fun one, activesupport >= 5 is broken on macOS System Ruby.

@segiddins do you know of any good ways to handle this?

endocrimes picture endocrimes on 15 Dec 2016

Use bundler and remove the activesupport <5 restriction is the only thing that comes to mind, but I know that isn't helpful

Install Cocoapods-app,
Click the button [ Install the command-Line Tool ].

@Raizo7777 thinks.this is a good idea.

KarlZeo picture KarlZeo on 27 Dec 2016

I may be wrong, but I'm pretty sure @Watson1978 is looking to use cocoapods with RubyMotion, so the Cocoapods app likely isn't a solution for him. Same goes for me.

Hey @DanToml is there any update on this? I can also downgrade Ruby to an earlier version I suppose, but I need CP for Swift 3...

topLayoutGuide picture topLayoutGuide on 3 Jan 2017

ATM we're stuck between a rock and a hard place, activerecord 5 doesn't support system ruby - and we have to support that.

As mentioned you can use the cocoapods Mac app ( by installing the app, and using the pod from inside that ) which will not have these problems, you can downgrade your Ruby, or you can try help the json gem get a 1.x release which continues to work with ruby 2.4.0

Same error. Hopefully I'm not breaking anything in the process but to fix I used:
Install RVM \curl -sSL https://get.rvm.io | bash -s stable
Install Ruby 2.3.3 rvm install ruby-2.3.3
Install cocoapods gem install cocoapods
And pod install is now working.

If you have errors from gpg installing RVM:
rm -rf ~/.gnupg/
curl -#LO https://rvm.io/mpapis.asc
gpg --import mpapis.asc
\curl -sSL https://get.rvm.io | bash -s stable

Cocoapods-app also allowed me to run pod install

jbschaff picture jbschaff on 7 Jan 2017

I have had success doing the following steps:

  1. Uninstall ruby via homebrew.
  2. Uninstall cocoapods
  3. Reinstall cocoapods under /usr/local/bin sudo gem install -n /usr/local/bin cocoapods
  4. reinstall ruby 2.4 via homebrew.

I have ruby 2.4 and cocoapods on my mac, and am able to run pod install without issue.

I'm seeing this same issue with Ruby 2.4.0, and sudo gem install -n /usr/local/bin cocoapods doesn't work - it just generates the same error. No errors after downgrading to 2.3.3.

Seems like fastlane fix this here: https://github.com/fastlane/fastlane/issues/7673#issuecomment-269417767, updating json gem to 1.8.5 or higher, cocoapods is using json 1.8.3

nebiros picture nebiros on 12 Jan 2017

json v1.8.5 was released (https://rubygems.org/gems/json/versions/1.8.5)
It can be built with Ruby 2.4.0 and this issue was solved by it.

Thank you all!!

The way it works for me..

  1. Install ruby using home-brew
    brew install rbenv ruby-build
    rbenv install 2.6.3
    rbenv global 2.6.3

    1. Install Cocoapods

      gem install cocoapods

      if system terminate the install. write "sudo" before "gem". I mean

      sudo gem install cocoapods
