'sudo gem install cocoapods' doesn't work on El Capitan 10.11.4 , ERROR: Could not find a valid gem 'cocoapods' (>= 0) in any repository

Question

Upgrading from Yosemite to El Capitan seem to have wiped out the already installed CocoaPods. When I pod install Alamofire/SwiftyJson, it says 'Pod command not found', and as per the stackoverflow solutions I uninstalled cocoapods and trying to reinstall it with the commands

 - sudo gem uninstall cocoapods
 - sudo gem install cocoapods

I get the error:

"Could not find a valid gem 'cocoapods' (>= 0) in any repository"

Did go through ALL the solutions mentioned by the Gurus under the issue https://github.com/CocoaPods/CocoaPods/issues/3736

mainly tried this which seem to have worked for many. still doesn't work for me.

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

tried modifying the permissions etc as per the solutions provided in the above link and the SO link

Nothing works, EVERYTHING leads to the same error "Could not find a valid gem 'cocoapods' (>= 0) in any repository"

I have also raised a issue on
