Ruby is a popular programming language used for web development, scripting, and other purposes. However, there might be instances where you’d like to uninstall Ruby from your Ubuntu system. In this blog post, we will guide you through the process of uninstalling Ruby.
Uninstalling Ruby using apt
If you installed Ruby using the apt package manager, you can easily uninstall it by executing the following command in your terminal:
sudo apt remove ruby
This command will remove the Ruby package along with its associated dependencies. To remove any leftover configuration files, execute the following command:
sudo apt purge ruby
Finally, update your package list by running:
sudo apt update
Uninstalling Ruby using RVM (Ruby Version Manager)
If you installed Ruby using RVM, the process to uninstall it is slightly different. First, list all the installed Ruby versions using the following command:
rvm list
This will display all the Ruby versions installed on your system. To remove a specific version, run the following command, replacing [ruby-version] with the version number you want to uninstall:
rvm remove [ruby-version]
For example, if you want to remove Ruby 2.7.1, you would run:
rvm remove 2.7.1
Uninstalling Ruby using rbenv (Ruby Environment)
If you installed Ruby using rbenv, you can uninstall it by first listing all the installed Ruby versions:
rbenv versions
Next, uninstall the desired Ruby version by running the following command, replacing [ruby-version] with the version number you want to remove:
rbenv uninstall [ruby-version]
For example, to remove Ruby 2.7.1, run:
rbenv uninstall 2.7.1
Conclusion
In this blog post, we covered the steps to uninstall Ruby from an Ubuntu system using various installation methods. Depending on whether you used apt, RVM, or rbenv, the uninstallation process may differ slightly, but the overall process is simple and straightforward. Always remember to replace [ruby-version] with the version number you wish to uninstall.
