Ruby is a popular programming language used by many developers around the world. In this blog post, we will walk through the process of updating your Ruby version on an Ubuntu system. This will ensure that you are using the latest and most secure version of Ruby, as well as provide you with access to new features and enhancements. Let’s get started!
Before we begin, make sure that you have a working installation of Ruby on your Ubuntu system. You can check the current version of Ruby by running the following command in your terminal:
Step 1: Install RVM (Ruby Version Manager)
RVM is a command-line tool that allows you to manage multiple Ruby versions on your system. To install RVM, open a terminal window and run the following command:
curl -sSL https://get.rvm.io | bash -s stable --ruby
This command will download and install RVM along with the latest stable version of Ruby. Once the installation is complete, load RVM into your current shell session using the following command:
Step 2: Update Ruby
Now that RVM is installed, you can update Ruby to the latest version. First, list all the available Ruby versions with the following command:
rvm list known
This will display a list of all the known Ruby versions. Find the latest version and install it using the following command (replace “x.x.x” with the desired version number):
rvm install x.x.x
Once the installation is complete, you can set the newly installed version as the default Ruby version for your system using the following command:
rvm use x.x.x --default
Replace “x.x.x” with the version number you previously installed. To confirm that the update was successful, check the Ruby version again in your terminal:
This should now display the updated Ruby version.
Step 3: Update RubyGems and Install Bundler
After updating Ruby, it is a good idea to also update RubyGems, the package manager for Ruby. To do this, run the following command:
gem update --system
Finally, install Bundler, a dependency manager for Ruby projects, by running the following command:
gem install bundler
Congratulations! You have successfully updated your Ruby version on your Ubuntu system. With this updated version, you can now enjoy the latest features, improvements, and security updates that Ruby has to offer. Remember to regularly check for updates to keep your system up-to-date and secure.
