Can't install cocoapods, report on pod setup

Question

I was following this tutorial http://www.raywenderlich.com/64546/introduction-to-cocoapods-2 to install cocoapods on my MacBook (Mavericks 10.9.5).

I have successfully used this commands

sudo gem update --system
sudo gem install cocoapods

But then whenever i use pod setup i get this log

    from /Users/tommy/.rvm/gems/ruby-2.1.1@msf/bin/pod:23:in `<main>'

It appears also if i type pod install.

What should I do? Thanks in advance

The latest version of cocoapods gem (v0.34.2) requires a version of xcodeproj gem >= 0.19.2. But the latest version of xcodeproj gem (0.19.3) causes this issue.

Managed to fix this by fixing the xcodeproj version to 0.19.2.

gem uninstall xcodeproj
gem install xcodeproj -v 0.19.2

or specify gem 'xcodeproj', '0.19.2' in your gemfile, then run bundle.

It's also worth noting that xcodeproj 0.19.3 seems to be working fine on Ruby 2.0.0, but this issue was happening on Ruby 1.9.3-p448 (for me anyway). So you can also try upgrading / switching your Ruby version. – odlp Oct 10 '14 at 12:53
