What causes this errors?
是什么导致这个错误？

It is a known bug with the current release of Sass, updating the sass stylesheet will cause the caching error because of the Sprockets importer not serializing correctly. For the bug report see this.
这是当前版本的Sass的已知错误，更新sass样式表将导致缓存错误，因为Sprockets导入器未正确序列化。对于错误报告，请看这个。

It is a bug in sprockets, but if, like me you are using an older version of Rails (3.2) you may be able to fix the bug by using a different version of sass. This guy was able to get it working with sass 3.1.x: https://github.com/rails/sass-rails/issues/242#issuecomment-66231135
这是链轮中的一个错误，但如果像我一样使用旧版本的Rails（3.2），您可以通过使用不同版本的sass来修复错误。这家伙能够使用sass 3.1.x：https：//github.com/rails/sass-rails/issues/242#issuecomment-66231135
The thread mentioned there gives some good context and an explanation for how to handle solving the issue or working around an inability to upgrade to a much newer, fixed version of sprockets.
这里提到的线程提供了一些良好的上下文和解释如何处理解决问题或解决无法升级到更新，固定版本的链轮。
Basically, use sass/sass-rails/sprockets from around the time Rails 3.2.x was supported.
基本上，在支持Rails 3.2.x的时候使用sass / sass-rails / sprockets。
