Published a gem before it was ready for release? Published a gem with the wrong name? Here's how you can fix it. You can use the gem yank command to remove versions from RubyGems.org's index using the command: ```ruby gem yank GEM -v VERSION ``` Running gem yank will remove your gem from being available with gem install and the other gem commands. This also removes the gem file, as of April 20, 2015. Note: Our webhook and mirror system means that several hundred services get pinged when new gems are pushed, so it's prudent to immediately reset any passwords/sensitive data you accidentally pushed even if you yank a gem right away.
