As of April 1, 2015, the latest version of Ruby [stable] is 2.2.1. I'm installing it from source to get latest and the greatest. This is a log of Ruby installations on my personal and office MacBooks, and development and production servers at work.
NOTE: I do not use rvm or rbenv because I like to have all my apps running with the same version of Ruby. If you have to run apps with different versions of Ruby, you'll need to install rvm or rbenv first.
Install dependencies and libraries
First, install the dependencies and libraries. We'll make sure to include support for OpenSSL and build tools.
On a Mac, assuming that you have Xcode tools and Homebrew installed:
xcode-select --install
brew install openssl
Find the openssl path:
brew --prefix openssl
It should return something like this:
/usr/local/opt/openssl
On Debian, run as root:
apt-get update
apt-get upgrade
apt-get install wget build-essential libssl-dev libpcre3-dev libcurl4-openssl-dev
On CentOS, run as root:
yum install gcc g++ make automake autoconf curl-devel openssl-devel zlib-devel
Download and install
Run this:
mkdir ~/downloads
cd ~/downloads
wget http://cache.ruby-lang.org/pub/ruby/2.2/ruby-2.2.1.tar.gz
tar -xzvf ruby-2.2.1.tar.gz
cd ruby-2.2.1
If you're on a Mac, use the configure command with this option:
./configure /usr/local/opt/openssl
If you're on Debian or CentOS, use the default command:
./configure
Continue the build:
make
sudo make install
Check if Ruby is installed with
ruby -v
You should get something like this.
ruby 2.2.1p85 (2015-02-26 revision 49769) [x86_64-darwin14]
Install Rails
sudo gem install rails
After several minutes, you will end up with Rails 4.2.1. Verify it with:
rails -v
You should see something like this.
Rails 4.2.1
Now, you can create your Ruby on Rails apps.
