Installing Cocoapods on OS X El Capitan error
First of all. I updated to El Capitan because of iOS 9.3 and it's support only in xCode 7.3.
After update I discovered that pod command isn't working.
I executed:
sudo gem install cocoapods
ERROR: Error installing cocoapods:
activesupport requires Ruby version >= 2.2.2.
So my problem is that I can't install cocoapods. I don't know nothing about gems and ruby stuff. Does somebody know how to handle this?
I had second OS X with El Capitan 10.11.4 and everything went ok so I don't know from where this issue is coming from.
UPDATE: 5 April 2016
I executed several commands on terminal for more info:

When I'm triying to install Ruby with rvm
Kapucha:local kapucha$ rvm install 2.2.2
Searching for binary rubies, this might take some time.

ERROR: '/bin' is not writable - it is required for Homebrew, try 'brew doctor' to fix it!

Tried brew doctor with the same result:

Answer
Here's a simpler solution than the other 'install homebrew/use rvm' suggestions -- first install an old version of 'activesupport' (which is both compatible with ruby 2.0 and with cocoapods) and then install cocoapods.
sudo gem install activesupport -v 4.2.6
sudo gem install cocoapods
Here's the cocoapods bug report that suggested this workaround.
