We will be setting up a Ruby on Rails development environment on Ubuntu 18.04 Bionic Beaver.
The reason we're going to be using Ubuntu is because the majority of code you write will run on a Linux server. Ubuntu is one of the easiest Linux distributions to use with lots of documentation so it's a great one to start with.
You'll want to download the latest Desktop version here: http://releases.ubuntu.com/18.04/
Some of you may choose to develop on Ubuntu Server so that your development environment matches your production server. You can find it on the same download link above.
We will install Ruby 2.5.1 & Rails 5.2.0
The first step is to install some dependencies for Ruby and Rails.
To make sure we have everything necessary for Webpacker support in Rails, we're first going to start by adding the Node.js and Yarn repositories to our system before installing them.
curl -sL https://deb.nodesource.com/setup_8.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 curl 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
There are some method to install Ruby on a unix system, such
rvm & from source.. we will be using
rbenv in this tutorial.
rbenv is a simple two step process. First you install
rbenv, and then
cd git clone https://github.com/rbenv/rbenv.git ~/.rbenv echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc echo 'eval "$(rbenv init -)"' >> ~/.bashrc exec $SHELL git clone https://github.com/rbenv/ruby-build.git ~/.rbenv/plugins/ruby-build echo 'export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"' >> ~/.bashrc exec $SHELL rbenv install 2.5.1 rbenv global 2.5.1 ruby -v
The last step is to install Bundler
gem install bundler
rbenv users need to run
rbenv rehash after installing bundler.
We'll be using Git for our version control system so we're going to set it up to match our Github account. If you don't already have a Github account, make sure to register. It will come in handy for the future.
Replace my name and email address in the following steps with the ones you used for your Github account.
git config --global color.ui true git config --global user.name "YOUR NAME" git config --global user.email "[email protected]" ssh-keygen -t rsa -b 4096 -C "[email protected]"
The next step is to take the newly generated SSH key and add it to your Github account. You want to copy and paste the output of the following command and paste it here.
Once you've done this, you can check and see if it worked:
ssh -T [email protected]
You should get a message like this:
Hi USER! You've successfully authenticated, but GitHub does not provide shell access.
To install NodeJS, we're going to add it using the official repository:
curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash - sudo apt-get install -y nodejs
And now, without further adieu:
gem install rails -v 5.2.0
You'll need to run the following command to make the rails executable available:
Now that you've installed Rails, you can run the
rails -v command to make sure you have everything installed correctly:
rails -v # Rails 5.2.0
If you get a different result for some reason, it means your environment may not be setup properly.
