Installing Cocoapods on OS X El Capitan error

Question

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:

Kapucha:~ kapucha$ which ruby

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.

Tried brew doctor with the same result:

Answer 1

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.

Answer 2

1. Install Homebrew using this command

   ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
   

2. Now that we have Homebrew installed, we can use it to install Ruby. We're going to use rbenv to install and manage our Ruby versions. To do this, run the following commands in your Terminal:

   brew install rbenv ruby-build
   

3. Now install ruby

   echo 'if which rbenv > /dev/null;
   
   then eval "$(rbenv init -)";
   
   fi' >> ~/.bash_profilesource ~/.bash_profile
   
   rbenv install 2.3.1
   
   rbenv global 2.3.1 
   
   ruby -v
   

4. install cocoapods

   sudo gem install cocoapods
   

Answer 3

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 https://github.com/Homebrew/homebrew.git 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

Answer 4

I used this command and work right:-

sudo gem install activesupport -v 4.2.6
 sudo gem install cocoapods
