Cannot run 'Pod Setup'

Question

CocoaPods returns error when I was trying to Pod install. Following are what I tried so far after some Google:

• As mentioned in http://blog.cocoapods.org/Repairing-Our-Broken-Specs-Repository/, I have removed and re-downloaded the master repo with sudo rm -fr ~/.cocoapods/repos/master/ and Pod Setup
• Reinstall CocoaPods and xcodeproj from gem
• Install with CocoaPods 0.36.0 beta

I am using Xcode 6.1.1 and Yosemite 10.10.2.

$ pod setup --verbose

Setting up CocoaPods master repo

I missed an issue in CococPods. It seems like the problem comes with psych 2.0.8 Pod setup error. #2908

sudo gem uninstall psych
sudo gem install psych -v 2.0.5
