Step 3: Next, run the shell script file using the below-mentioned command:

$ curl -fsSL https://github.com/rbenv/rbenv-installer/raw/HEAD/bin/rbenv-installer | bash

Step 4: To start using Rbnev, you will need to update the path environment using the following shell script command:

$ echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
echo 'eval "$(rbenv init -)"' >> ~/.bashrc
source ~/.bashrc

Step 5: Once Rbnev installation is completed, you can then list the Ruby version using the following command.

$ rbenv install -l

Step 6: Now, use the following command to install the latest version of Ruby on Ubuntu:

$ rbenv install ruby 3.1.2

Step 7: To set the installed version of Ruby as a global, execute the following command:

$ rbenv global 3.1.2

To confirm the latest Ruby version, use the following command.

$ ruby --version

$ sudo apt install curl g++ gcc autoconf automake bison libc6-dev libffi-dev libgdbm-dev libncurses5-dev libsqlite3-dev libtool libyaml-dev make pkg-config sqlite3 zlib1g-dev libgmp-dev libreadline-dev libssl-dev

Step 3: Now, install RVM by executing the below-given command:
