在尝试为 chrome http://blog.vhyza.eu/blog/2013/09/22/debugging-rails-4-coffeescript-and-sass-source-files启用源映射后，我从 heroku 收到以下警告-in-google-chrome/ 他们表示什么，如果有的话，我应该改变什么？

我能够通过降级我的 sass gem（由 sass-rails 引入）来解决这个问题。

我的 Gemfile 现在包含：

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

我发现问题出在我的 env 文件中。

config.cache_store = :dalli_store

我知道这是帮助加快编译速度所必需的，但我现在可以不用它，直到我找到它并找到正确修复它的方法。

在写这篇文章时我也遇到了同样的问题，但后来我正在使用sass-rails 5.0.0.beta1，但我确认你可以升级到最新版本，而不是降级sass-rails 5.0.0，一切都会好起来的。升级到最新版本而不是降级。
