Techie June 2020
In this tutorial we are going to set up Ruby and Ruby on Rails development environment on Ubuntu 18.10 Cosmic Canimal.
Ubuntu version: 18.10
Ruby version: 2.7.1
Rails version: 6.0.2.2
STEP 1: Install dependencies for Ruby and Rails
# Add the Node.js and Yarn repositories to our system before installing them to make sure we have everything necessary for Webpacker support in Rails.
sudo apt install curl
curl -sL https://deb.nodesource.com/setup_12.x | sudo -E bash -
curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -
echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list
sudo apt-get update
sudo apt-get install git-core zlib1g-dev build-essential libssl-dev libreadline-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt1-dev libcurl4-openssl-dev software-properties-common libffi-dev nodejs yarn
STEP 2: Install Ruby: Using rbenv
#1. Install rbenv.
cd
git clone https://github.com/rbenv/rbenv.git ~/.rbenv
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
echo 'eval "$(rbenv init -)"' >> ~/.bashrc
exec $SHELL
#2. Install ruby-build.
git clone https://github.com/rbenv/ruby-build.git ~/.rbenv/plugins/ruby-build
echo 'export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"' >> ~/.bashrc
exec $SHELL
rbenv install 2.7.1
rbenv rehash
rbenv global 2.7.1
# Verify Ruby version
ruby -v
STEP 3: Install bundler
gem install bundler
rbenv rehash
STEP 4: Install Ruby on Rails
gem install rails -v 6.0.2.2
rbenv rehash
# Verify Rails version
rails -v
That’s it!
See you in the next tuts
