I've followed your instructions & uninstalled all gem. but when I tried to install cocoapods it is giving following error.

Please advice. . .

Thanks

Finally I got Solution For installation of CocoaPods in OS X El Capitan

First remove or uninstall all available Gems by using following command in your terminal(which is located in your Launchpad>Other>Terminal or you can also find that in Finder>Applications>Utilities>Terminal)

gem uninstall --all
sudo gem uninstall --all

When after successful uninstallation of all Gems, Then write following command in your terminal

sudo gem install -n /usr/local/bin cocoapods
pod setup

Hope all of you will be awaiting for this answer. anyway, this works for me hence according to me it is best suitable solution to that particular problem.
