ruby-on-rails - 没有路由匹配 [GET] "/assets/bootstrap.css.map"

Question

我在 rails4，bootstrap 3 上运行，我在终端中收到以下错误消息。

Started GET "/assets/bootstrap.css.map" for 127.0.0.1 at 2014-08-24 23:41:36 -0700

任何人有任何想法如何摆脱这个？

编辑:

这是我的 application.css

*= require_tree .
*= require_self
*= require_ladda-themeless
*= require login_form
*= require bootstrap

请求 bootstrap.css.map 的文件是:
/vendor/assets/stylesheets/bootstrap.css
删除最后一行应该可以解决问题:

/*# sourceMappingURL=bootstrap.css.map */

见 here map 文件是做什么用的。
