Sass :: SyntaxError at /未找到选择器“.date”

Question

最近安装了Ubuntu 14.04 amd64并且还安装了rails 3.2.16，但是当我尝试运行rails应用程序时，我遇到了Ubuntu 12.04 amd64中没有的错误：

Sass::SyntaxError at /
".date" failed to @extend ".date".
The selector ".date" was not found.
Use "@extend .date !optional" if the extend should be able to fail.

如果我使用！optional有下一个错误：

"#sub-header-schedules .modal .dialog" failed to @extend ".modal-lg".
The selector ".modal-lg" was not found.
Use "@extend .modal-lg !optional" if the extend should be able to fail.

在终端服务器中，我得到以下内容：

Answer 1

您需要更改application.css.scss中的排序，如下所示：

/*
*= require jquery.ui.core
*= require jquery.ui.theme
*= require _font-awesome
*= require token-input-facebook
*= require dataTables/src/demo_table_jui
*= require bootstrap-multiselect
*= require bootstrap-datetimepicker
*= require fullcalendar
*= require fullcalendar.print
*= require dataTables/extras/TableTools
*= require dataTables/extras/TableTools_JUI
*/

/* Shifted below mentioned line */
/*
*= require_self
*= require_tree .
*/

@import "bootstrap";

schedules.css.scss加载了*= require_tree .语句，当您使用其他库中定义的类时，需要先加载它们才能在schedules.css.scss中使用

我遇到了bootstrap-sass版本的问题。 解决了它：

gem uninstall bootstrap-sass -v 3.1.1.1 && gem uninstall bootstrap-sass -v 3.1.1.0
