Question

我有一个基于Michael Hartl的Rails教程的Ruby on Rails网络应用程序。在过去的一周里，我尝试在我拥有的服务器上运行生产设置。当前的设置包括Ubuntu Server 12.04 LTS，RVM，Ruby 1.9.3，Rails 3.2.8，Apache2，MySQL和＆amp;乘客。

我能够在网上获得该应用，但它有错误。 Ubuntu机器在浏览器中显示错误（包括在下面）。但是，除非我预编译我的资产，否则我的Windows 7开发计算机上不存在该错误。基于twitter bootstrap-sass gem的样式表资产似乎是罪魁祸首。如果我删除custom.css.scss的内容，应用程序加载没有错误，但显然没有样式。如果我只包含@import“bootstrap”; custom.css.scss文件中的语句仍有错误。我也尝试了gem bootstrap-rails并遇到了同样的错误。如果您需要更多信息来回答这个问题，请与我们联系。谢谢！
