Installing Ruby using rbenv on your WSL Ubuntu system is a great way to manage multiple Ruby versions. Below are the step-by-step instructions:
Step 1: Update Your Package List
First, ensure your package list is up to date.
sudo apt update
Step 2: Install Dependencies
Install the necessary dependencies for rbenv and Ruby.
sudo apt install -y build-essential libssl-dev libreadline-dev zlib1g-dev libffi-dev libyaml-dev
Step 3: Install rbenv
Clone the rbenv repository from GitHub and add it to your shell.
git clone https://github.com/rbenv/rbenv.git ~/.rbenv
~/.rbenv/bin/rbenv init
Step 4: Install ruby-build
Clone the ruby-build repository into the rbenv plugins directory.
git clone https://github.com/rbenv/ruby-build.git "$(rbenv root)"/plugins/ruby-build
Step 5: Install Ruby
List all available Ruby versions.
rbenv install -l
Install your desired Ruby version (replace 3.3.4 with the version you want to install).
rbenv install 3.3.4
rbenv global 3.3.4 # to activate this Ruby version as the new default
Step 6: Verify the Installation
Check the Ruby version to ensure it was installed correctly.
ruby -v
Step 7: Install Bundler
Install the Bundler gem, which is essential for managing Ruby project dependencies.
gem install bundler
Step 8: Rehash rbenv
Rehash rbenv to ensure it recognizes the new Ruby installation.
rbenv rehash
Additional Notes
-
Updating rbenv and ruby-build: Occasionally, you might need to update
rbenvandruby-build. You can do this by navigating to their respective directories and pulling the latest changes from GitHub:
cd ~/.rbenv
git pull
cd ~/.rbenv/plugins/ruby-build
git pull
- Switching Ruby Versions: To switch Ruby versions, simply install the desired version and set it globally or locally for a specific project:
rbenv install x.x.x
rbenv global x.x.x # For system-wide
# or
rbenv local x.x.x # For a specific project
Following these steps will help you successfully install and manage Ruby versions using rbenv on your WSL Ubuntu system.
