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
$ ruby -v
$ curl -sSL https://get.rvm.io | bash -s stable
$ rvm requirementsNOTE: 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.
$ rvm install 2.0.0 --with-openssl-dir=$HOME/.rvm/usr
install: —no-rdoc —no-ri update: —no-rdoc —no-riInstall Rails
$ gem install railsYou 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.
