Currently if you would bundle update you would end up with sassc (2.0.0) which breaks on precompiling assets with Error: error C function image-url: initialised constant SassC::Script::String
Locking down the sassc gem solves this issue.
gem 'sassc', '~> 1.0', require: false
I will try and figure out what breaks and get a solution for sassc ‘~> 2.0’…
I am definitely for the more ideal version of just figuring out how to upgrade sassc. PR totally welcome on that. It is going to be related to our sass customizations for themes and so on.
