How to install Ruby on Ubuntu

Method 1: Installing Ruby using the Default Package Manager

1. Update the package list

Open a terminal and update the package list to make sure you have the latest information about available packages

sudo apt update

2. Install Ruby

To install the default version of Ruby provided by Ubuntu's package manager, you can use the following command

sudo apt install ruby-full

This will install the Ruby interpreter and other related tools.

 

3. Check the Ruby Version

After installation, you can verify the Ruby version by running

ruby -v

It should display the installed Ruby version.

Method 2: Installing Ruby using RVM (Ruby Version Manager)

RVM is a popular tool for managing Ruby versions. Here's how to install Ruby using RVM

 

1. Install Dependencies

Before installing RVM, make sure you have the necessary dependencies installed

sudo apt update

sudo apt install curl gpg

2. Install RVM

Use the following command to install RVM

curl -sSL https://get.rvm.io | bash -s stable

This will download and install RVM.

 

3. Load RVM

To use RVM, you need to load it into your shell session. Run the following command or open a new terminal session

source ~/.rvm/scripts/rvm

 

4. Install Ruby

Now, you can install the desired version of Ruby using RVM. For example, to install Ruby 2.7.4, use the following  command

rvm install 2.7.4

 

5. Set Default Ruby Version (Optional)

You can set the newly installed Ruby version as the default version using

rvm use 2.7.4 --default

 

6. Check Ruby Version

Verify the installed Ruby version by running

ruby -v

 

Now you have Ruby installed on your Ubuntu system using either the default package manager or RVM, depending on your preference.
