Heroku：保存缓存时遇到错误

问题描述

本地一切正常，但推向Heroku时：

我的production.rb文件启用了以下属性：

  config.cache_classes = true 
 
 config.consider_all_requests_local = false 
 config.action_controller.perform_caching = true 
 
 config.serve_static_assets = true 
 
 config.assets.compress = true 
 config.assets.compile = false 
 
 config.assets.digest = true 
 config.assets.initialize_on_precompile = false 
  
  
 
 
我的Rails版本是Rails 3.2.11  
 
解决方案
这与sass gem最近升级到3.3.0有关。 sass gem是一些其他sass gems的依赖项，所以即使你没有在你的Gemfile中，它也可能被加载。在本地和Heroku上进行捆绑秀，我相当肯定你会看到他们是不同的版本（几天前sass升级到3.3.0）。
 
 
 Add：
  gem'sass'，'3.2.13'
  
添加到您的Gemfile，并且应该为您解决问题。然后在github上为这个宝石提交一个问题。
 
 
 
希望这会有帮助，它对我有用！

My rails version is Rails 3.2.11
 解决方案 
This is related to the recent upgrade of the sass gem to 3.3.0. The sass gem is a dependency of a couple of other sass gems, so even if you don't have it in your Gemfile, it is probably getting loaded. Do a "bundle show" locally and on Heroku and I'm fairly sure you'll see they are different versions (sass was upgraded to 3.3.0 just a couple days ago).
Add:
gem 'sass', '3.2.13'
to your Gemfile and that should fix things for you. Then go submit an issue on github for this gem.
Hope this helps, it worked for me!
