To install the gem package on Debian or Ubuntu, you can use the following steps:
- Update the package index:
sudo apt-get update
- Install the
rubyandrubygemspackages:
sudo apt-get install ruby rubygems
- Verify that the
gempackage is installed by checking the version:
gem -v
This will output the version number of the gem package, which is the front-end to the RubyGems package manager. You can now use gem to install, manage, and update Ruby gems and their dependencies on your Debian or Ubuntu system.
