Installing Rails

[Bryan Singh]

I am trying to install Rails onto a new computer, running  OS X El Capitan.

I run 

rbenv install 2.3.1

 and then it errors out and I get

Downloading ruby-2.3.1.tar.bz2...

-> https://cache.ruby-lang.org/pub/ruby/2.3/ruby-2.3.1.tar.bz2

Hello, 

You have installed Xcode ??

 P.S. why not rvm ?? :)

Br,

if it fails after you installed Xcode you might need to run

$ xcode-select --install
