sass error в rails app on heroku: не может свалить анонимный класс

Question

Я получаю следующие предупреждения от героку после попытки включения исходных карт для хрома http://blog.vhyza.eu/blog/2013/09/22/debugging-rails-4-coffeescript-and-sass-source-files-in-google-chrome/ Что они указывают и что, если что-нибудь, следует изменить?

Answer 1

Я обнаружил, что проблема была это в моем файле окр.

config.cache_store = :dalli_store 

Я знаю, что это нужно сделать, чтобы ускорить компиляцию, но я могу обойтись без него сейчас, пока я не нашел назад и узнал, как исправить это правильным.

Answer 2

Я был в состоянии обойти эту проблему, понизив свой драгоценный камень (который вводился сассовыми рельсами).

Мои Gemfile теперь содержит:

gem "sass", "~> 3.2.5" 
gem 'sass-rails' 

Answer 3

У меня была такая же проблема на момент написания этого поста, но тогда я использовал sass-rails 5.0.0.beta1 но я подтверждение того, что вместо понижения вы можете обновить до последней sass-rails 5.0.0 и все будет хорошо. Сделайте обновление до последней версии вместо понижения.
