Heroku fails on precompiling assets once it reaches application.scss

Question

I don't get any errors locally, but when I push to Heroku (I don't precompile locally) I get this:

...

end

# Use Uglifier as compressor for JavaScript assets
group :assets do
    gem 'therubyracer', platforms: :ruby
    gem 'uglifier', '>= 1.3.0'
end

I'm not sure what else to show that will help. I'm using the Foundation framework and compass, and I have it configured so that Heroku does the precompiling of assets.

Answer 1

There are a lot of problems right now with many gems that depend on sprockets in some way. This might be an issue with compass-rails issue#144 I am trying to send a pull request with a fix for new.

In the meantime you need to lock sprockets to 2.11 in your Gemfile. Add this to your Gemfile

gem "sprockets", "2.11.0"

and run

bundle update sprockets

Writing /tmp/build_61158595-7e19-4bb5-88f0-728f7ab59f3f/public/assets/jquery-2.0.3.min-85a805038cb99ffbfec3467f84cad4c0.map

wrong number of arguments (2 for 1)

I think your error is to do with your JS - are you calling JQuery again or something? What about any calls in your application.js -- are you calling a function with more than one argument?
