Installation

Clone the repository on your computer and change into the projects folder. Run:

$ bundle
$ bower install
$ npm install

Hint: If you get errors while installing gulp-imagemin it may help to execute this command before running npm install:

export PKG_CONFIG_PATH=/opt/X11/lib/pkgconfig

Hint: I recently ran into problem with gulp-imagemin. This may be an error with my current version of node. But if you get the same error on gulp publish, while optimizing images install manually these files:

$ npm install optipng-bin
$ npm install cwebp-bin

To install Fontcustom you should have Homebrew installed or use another package management tool to install the dependencies:

$ brew install fontforge --with-python
$ brew install eot-utils

Setup

Open gulp/config.js and change settings if needed. Only the rsync settings need to be adjusted. Change the destination to a path on your webserver and change hostname and username.

Running Gulp.js

Three tasks are available:

$ gulp
$ gulp publish
$ gulp deploy

• Running gulp will start a development server, build assets and the Jekyll site and start a watch task.
• Running gulp publish will copy and optimize assets and run a production build of Jekyll.
• Running gulp deploy will copy the generated files with Rsync to your server.

Sass, Compass or PostCSS

The current version of this tutorial uses PostCSS. If you would like to use Sass (or Compass), you can still easily access the old code in the branch ruby-sass. The new code at the time I wrote the article is available in the branch postcss. Additionally I merge it into master and will process with PostCSS in my tutorial.
