How I build and install specific versions of ruby

First, I use ruby-build.

Install ruby-build

Dependencies:

sudo apt-get install -y libreadline-dev

Download the source:

ᐅ git clone https://github.com/rbenv/ruby-build.git

Run the install script

ᐅ PREFIX=/usr/local sudo ./ruby-build/install.sh

Now we can install a specific version of ruby..

Got a project that needs some 2.3.x? Let’s build 2.3.0!
