I'm getting the following warnings from heroku after trying to enable source maps for chrome http://blog.vhyza.eu/blog/2013/09/22/debugging-rails-4-coffeescript-and-sass-source-files-in-google-chrome/ What do they indicate and what, if anything, should I change?
在尝试为chrome创建源地图后，我从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 /它们表示什么，如果有的话，我应该改变什么？

I found out that the problem was this in my env file.
我发现问题出在我的env文件中。
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.
我知道这需要帮助加快编译速度，但是我现在可以不使用它直到我找回来并找到了如何正确修复它。

I was able able to work around this issue by downgrading my sass gem (which was being brought in by sass-rails).
通过降级我的sass gem（由sass-rails引入），我能够解决这个问题。
My Gemfile now contains:
我的Gemfile现在包含：
gem "sass", "~> 3.2.5"

I had this same problem at the time of writing this post but then I was using sass-rails 5.0.0.beta1 but I'm confirming that instead of downgrading you can upgrade to the latest sass-rails 5.0.0 and everything will be fine. Do an upgrade to the latest version instead of downgrading.
我在编写这篇文章时遇到了同样的问题，但后来我使用的是sass-rails 5.0.0.beta1，但我确认不是降级你可以升级到最新的sass-rails 5.0.0而且一切都会精细。升级到最新版本而不是降级。
