Answer 1

It seems you are not using any package manager. Since, you don't have write permission to this directory, there is nothing wrong in using sudo for gem install.

However, I prefer changing ownership of that directory, so that I don't have to use sudo every time.
i.e. sudo chown -R [login name] /Library/Ruby/Gems/2.0.0

and ensure that I have write permission. sudo chmod -R u+w /Library/Ruby/Gems/2.0.0

Consider using rvm (ruby version manager) or rbenv

Answer 2

 sudo gem install cocoapods

works for me

Answer 3

This is the solution when you are receiving the "Operation not permitted" error.

$ mkdir -p $HOME/Software/ruby
$ export GEM_HOME=$HOME/Software/ruby
$ gem install cocoapods
[...]

Answer 4

You need to 'update Gems'. Open terminal, then do this

sudo gem update

That's enough.
