heroku上rails应用程序中的sass错误:无法转储匿名类

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?

我发现问题出在我的env文件中。

 config.cache_store = :dalli_store 

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。

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

我的Gemfile现在包含:

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

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。
