It organizes each package in an isolated directory and uses symlinks to integrate them into your system. | RubyGems is an open-source package hosting and distribution platform where Ruby developers discover, install, and publish gems (libraries). As a free, community-maintained service, it processes billions of downloads and is central to the Ruby development ecosystem. |
