Ruby on Rails 应用程序在部署时不重新生成样式表
我有一个 Ruby on Rails 应用程序无法正确生成样式表。有时 SASS 不会将 SCSS 编译为 CSS，有时不会生成它们串联的 CSS。我基本上在编写文件时遇到错误，如下所示：

整个 /var/www/app 被设置为属于 www-data:www-data ，权限为 ug+rwX，在部署时有几次。
即使在部署之后，我可以去检查权限，它们都很好：
# ls -la current/public/stylesheets/
total 92
drwxrwxr-x 2 www-data www-data 4096 Oct 4 14:11 ./
drwxrwxr-x 6 www-data www-data 4096 Oct 4 13:49 ../
但它仍然无法创建（或读取文件）。
有什么想法可能会发生什么吗？
I have a Ruby on Rails application that is not generating stylesheets properly. Sometimes SASS doesn't compile the SCSS into CSS and sometimes they concatenated CSS are not generated. I basically get an error writing the files, like this:

The whole /var/www/app is set to belong to www-data:www-data with permissions ug+rwX, a couple of times at deploy time.
Even after deploying I can go and check the permissions and they are fine:
# ls -la current/public/stylesheets/
total 92
drwxrwxr-x 2 www-data www-data 4096 Oct 4 14:11 ./
drwxrwxr-x 6 www-data www-data 4096 Oct 4 13:49 ../
and it still fails to create (or read the files).
Any ideas what might be going on?
