问题描述

在尝试为chrome启用源地图后，我收到来自heroku的以下警告 http://blog.vhyza.eu/blog/2013/09/22/debugging-rails-4-coffeescript-and-sass-source-files -in-google-chrome /
它们表示什么以及应该更改什么内容？

解决方案

问题是这是在我的环境档案。

  config.cache_store =：dalli_store 
  

我知道这是帮助加速编译所需的，但现在我可以不用它，直到我找回来并找出如何解决问题。

解决方案

I found out that the problem was this in my env file.

config.cache_store = :dalli_store

I know this is needed to help speed up compilation, but I can do without it for now till I found back and found out how to fix it proper.
