You will need Ruby ( > version 2.2.4 ). To check
whether it's already installed on a UNIX-like system, open up a terminal
window (e.g. Terminal on OS X) and type
ruby -v at the command prompt. For
example, you should see something similar to the following:
$ ruby -v ruby 2.2.4p230 (2015-12-16 revision 53155) [x86_64-darwin15]
If the version number is less than 2.2.4, or instead you see something like:
$ ruby -v -bash: ruby: command not found
Then Ruby is not installed, and you should choose one of the installation methods below. The "Installing Ruby" page of the official Ruby language web site explains how to do this in a number of ways across many different systems.
On OS X, you can use Homebrew to install Ruby in
/usr/local/bin, which may require you to update your
$ brew update $ brew install ruby
Whether or not Ruby is already installed, we strongly recommend using a Ruby version manager such as rbenv or rvm to help ensure that Ruby version upgrades don't mean all your gems will need to be rebuilt.
To create a new guide and serve it locally, where
MY-NEW-GUIDE is the name
of your new repository:
$ git clone https://github.com/18F/guides-template.git MY-NEW-GUIDE $ cd MY-NEW-GUIDE $ ./go serve
./go script will check that your Ruby version is supported, install the
Bundler gem if it is not yet installed, install all the
gems needed by the template, and launch a running instance on
