Cocoapods are dependency manager for Swift and Objective-C that maintains external libraries. I had to install this to make use of AWS libraries for iOS application.

This can be installed with the Ruby which is already available on OS X El Capitan. The installing process seem to be simple as mentioned in their official website, but I faced a couple of issues which I wanted to share, so it saves time for others who faces similar issues.

First, I updated the Ruby version. Open terminal, type the below command.

$ sudo gem update --system

Then, run the command to install Cocoapods.

$ sudo gem install cocoapods

This will ask you to enter the password. Once I typed in my mac login password and hit enter, it threw me the below error.

ERROR:  Error installing cocoapods:
activesupport requires Ruby version >= 2.2.2.

After googling this for a while, I ran this command (not sure if this is necessary).

$ sudo gem install activesupport -v 4.2.6

After it installed active support version 4.2.6, I ran the cocoapod installation command again which gave me another error.

$ sudo gem install cocoapods

After reading a few forums, I found there is a problem with OS X El Caption which has access issues to system, so I was suggested to run this for a specific user folder.

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

That worked for me. Now, you can install the external libraries in your projects.
