I am on Mac version 10.11.3 OS X El Capitan I am facing following error while updating cocoapods to latest version.
You don't have write permissions for the /Library/Ruby/Gems/2.0.0 directory.
I also tried:
sudo gem install cocoapods -pre

Your comment seems to link to a different problem. I already posted an answer here with a relevant solution. – Cœur Oct 23 '18 at 02:06

Starting with El Capitan, Apple prevents user applications to modify /usr/bin for security reasons. So just install/update rubygems in the recommended folder, /usr/local/bin:
sudo gem install cocoapods -n /usr/local/bin --pre

You don't have permissions to install gems. You had to use sudo before so now your permissions aren't correct.
Easy solution:
Run this command with sudo:
sudo gem install cocoapods -pre
Better solution - install cocoapods for this user only:
gem install --user-install cocoapods -pre
Another solution - fix your permissions:
sudo chown -R YOUR_USERNAME:YOUR_GROUP ~/.rvm
sudo chown -R YOUR_USERNAME:YOUR_GROUP ~/.gem
or
sudo rvm fix-permissions YOUR_USERNAME:YOUR_GROUP

Since you installed the beta version, I don't recommend installing with
sudo gem install cocoapods -pre
if you use -pre you gonna install the beta version, Instead, use
sudo gem installcocoa pods
Your main problem is that, and you didn't use sudo to give the necessary permissions.
