Installing Drupal Omega 4 dependencies on Mac OS X
Omega 4 is a powerful base theme for Drupal 7.
But powerful has some disadvantages: in order to run Sass and Compass in combination with Omega 4 on your local machine, you need several dependencies.
In this tutorial I will show how to install these dependencies.
- A dev stack
For the Dev stack, check this tutorial.
GCC is a GNU compiler. GCC comes shipped with Xcode, but to check if it’s installed, run the following command:
Homebrew is a package manager for OS X.
Install with this command:
curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install
On Mavericks/Yosemite you can use the default Ruby 2.0 but if you break something, you break the whole system. So it’s recommended to use Ruby Version Manager with Ruby 1.9.3.
Install Ruby (this can take a while):
curl -L https://get.rvm.io | bash -s stable
And add this to your .bash_profile:
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*
(Replace && with &&)
Omega 4 asks for version 1.9.3. So, next, we need to install the latest stable version in the 1.9.3 branch.
rvm install ruby-1.9.3-p551
And set it as default:
rvm --default use 1.9.3-p551
Bundle installs the correct gems for your theme in the .rvm folder, so every theme can have it’s own gems:
gem install bundler
Finally, do all the necessary checks:
- php -v
- drush status
- brew list
- rvm -v
- ruby -v
When all these checks are ok, install your Omega 4 sub theme with 'drush omega-wizard' and after that, browse to the newly created theme folder and run 'drush omega-guard'. This last command should create a new gemset.
