Rails generate figaro:install is not generating .yml file

Question

I've just started on the book Learn Ruby on Rails. On the configuration file chapter it states running "rails generate figaro:install" should generate a config/application.yml file. I ran it and kept getting an error. There was a gem I had trouble installing which was gem 'compass-rails', '~> 2.0.alpha.0' and the only one available alternative was gem "compass-rails", "~> 1.1.3". I'm not sure if that has anything to do with the fact that I keep getting this error. I also posted at the bottom what I get when I try to run this command.

Answer 1

I ran into the same issue with figaro -- it appears to be related to the newer version of the sass gem, which is included as a dependency of compass. I fixed by adding the following to my gemfile, per this suggestion (newer releases of sass may work, too).

gem 'sass', '3.3.0.alpha.149'

You'll probably need to run bundle update sass from the command line as well. Hope that helps!
