How to: Install, Update and Remove RubyGems

I just had a brief experience installing a (https://rubygems.org “RubyGems”) so I thought I would share a little bit of what I learned about managing RubyGems. Similar to packages (apt-get) you can search through them, install them, remove them, and update them with simple commands. Below is a brief summary designed just to quickly point individuals to the instructions needed to accomplish the management of RubyGems:

  1. Searching (where mysql is the the search term: it will find any gem that contains the word mysql. The address after --remote indicates the online library where the search will be performed)
    1. gem search mysql --remote gems.rubyforge.org
  2. Installing (where mysql is the gem you are installing and --include-dependencies indicates an automatic answer to yes when it asks to install a needed dependency)
    1. sudo gem install mysql
    2. sudo gem install mysql --include-dependencies
  3. Updating (you may update all gems or specify a particular one like mysql)
    1. sudogem update
    2. sudo gem update mysql
  4. Removing (where mysql is the gem you wish to uninstall)
    1. sudo gem uninstal l mysql
  5. Clean / Removes old versions (I still struggle to understand the difference with update)
    1. sudo gem clean
  6. List installed Gems
    1. gem list
