I was enable to run app without specifying sprockets version

[Maxim Filippov]

After I cloned app I tried to run it and was getting:

ArgumentError at /
wrong number of arguments (2 for 1)
(in /Users/Max/Code/Ruby/gems/auto_select2_tag_example/vendor/bundle/gems/select2-rails-3.5.9.1/vendor/assets/stylesheets/select2.scss)

I found this issue, where @brentmulligan suggests to use gem 'sprockets', '2.11.0' to avoid this issue, it helped me. Maybe you should add this to your Gemfile?

Fixed 'sprockets' and 'sass-rails' versions.
