When developing for Ruby on Rails the first thing you'll need to set up your development environment. This guide will be for installing things on Mac OSX and would be similar for Linux. These are my notes from experience setting up a Rails environment based on The Rails Tutorial
by Michael Hartl.
New Rails Installation on OSX
Checks if git is installed and if it isn’t it will install it
Install Ruby (Already installed)
Checks Ruby version, already installed on OSX
$ ruby -v
RVM is for multiple Ruby on Rails environments for different projects.
$ curl -sSL https://get.rvm.io | bash -s stable
Install RVM Requirements
$ rvm requirements
NOTE: RVM tries to install gcc46 which is an older version of gcc on OSX. Mavericks already has gcc installed so install the list that appears except gcc. It also can install but take a VERY long time so just be patient and see.
Tell RVM where OpenSSL is
$ rvm install 2.0.0 --with-openssl-dir=$HOME/.rvm/usr
This file stops the installation of Ruby docs, the text below goes in .gemrc
install: —no-rdoc —no-ri
update: —no-rdoc —no-ri
$ gem install rails
You should be ready to create your environment and install your Gems. If I've missed anything, or you have problems, let me know in the comments below and I will update this list.
