iOS Question

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

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:

Kapucha:~ kapucha$ which ruby
Kapucha:~ kapucha$ which gem

Searching for binary rubies, this might take some time.

Tried brew doctor with the same result:

Finally I solved this problem.

The goal was to install cocoapods but there was errors that I need ruby >= 2.2.2.

Installation rvm install 2.2 didn't completed because of error:

/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/fileutils.rb:245:in `mkdir': Permission denied - /Library/Ruby/Gems/2.0.0/extensions/universal-darwin-15 (Errno::EACCES)

Running brew was resulting with the same error. So I decided to fix brew first. It was fixed by uninstalling and installing it again. It wasn't easy. Uninstall script did't work because I didn't have .git folder in /usr/local.

I decided to provide .git folder.

I cloned git clone to some temp folder and then cp -r .git /usr/local/ so in the end I have .git folder in my brew folder /usr/local. After this I was able to Uninstall and Install fresh brew on El Capitan. Take a look at Part 2 of this link.

With working brew and fixed permissions for El Capitan in /usr/local according to this I was able to install ruby with rvm:

rvm install 2.2
rvm use 2.2

and install cocapods finally for El Capitan:

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