What is Ruby Gems 2.6.0?
/Library/Ruby/Gems/2.6.0 is a shared gem directory used by Ruby 2.6 on macOS. Gems are Ruby packages that add features for command-line tools, scripts, development workflows, and some older software components. People often encounter this folder after installing gems with sudo gem install or when troubleshooting Ruby-based tools.

Safety overview
Status: Use with caution
This is not typically user data, but removing or changing its contents can break Ruby-based commands, scripts, and development tools that depend on installed gems. Because it sits under /Library, it may be shared across users and may have been used by system-provided or manually installed Ruby tooling.
Recommendation: Keep this folder unless you are sure you no longer use Ruby 2.6 gems installed at the system level. If you are cleaning up developer tools, first identify which gems are installed and whether any scripts or automation still rely on them. Avoid deleting individual files blindly; review the installed gems and your Ruby setup before making changes.
