Question

我嘗試啓用chrome源地圖後，從heroku收到以下警告http://blog.vhyza.eu/blog/2013/09/22/debugging-rails-4-coffeescript-and-sass-source-files-in-google-chrome/ 它們表示什麼，以及應該更改哪些內容？

Answer 1

我發現問題是這在我的ENV文件。

config.cache_store = :dalli_store 

我知道這是需要幫助加快編制，但我可以沒有它現在直到我發現後發現瞭如何解決它正確的事情。

Answer 2

我能夠通過降級我的sass gem（這是由sass-rails引入的）來解決此問題。

我的Gemfile現在包含：

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

Answer 3

我有同樣的問題在寫這篇文章的時間，但後來我用sass-rails 5.0.0.beta1，但我確認，而不是降級，你可以升級到最新的sass-rails 5.0.0一切都會好的。升級到最新版本而不是降級。
