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:
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.
