CocoaPods Failing to install with Xcode 5.0.2

Question

I have been stuck on this issue for a couple hours now and I cannot find a solution. I am running Mavericks and have Xcode 5.0.2 installed (which comes with the Command Line Tools).

My environment:

• using RVM with ruby version 1.9.3p484
• Xcode 5.0.2
• Mac OS 10.9.1
• Gem 2.2.0
• Bundler version 1.3.5

Sudo gem install cocoapods outputs

kyles-mbp-2:fresh-driver-ios kylechronis$ sudo gem install cocoapods

     ERROR:  Error installing cocoapods:

   CoreFoundation is needed to build the Xcodeproj C extension.
    *** extconf.rb failed ***
   Could not create Makefile due to some reason, probably lack of
   necessary libraries and/or headers.  Check the mkmf.log file for more
   details.  You may need configuration options.

Is this an issue with CoreFoundation not being found? or using a different version of Ruby? Any help or input would be greatly appreciated.

Answer 1

Installing new Ruby version helped me. Follow these steps

rvm reinstall ruby-2.0.0-p247 --with-gcc=clang --verify-downloads 1
gem install xcodeproj
gem install cocoapods

I found this answer in some old Github issue.
