Sass::SyntaxError at / The selector ".date" was not found

Question

Recently installed Ubuntu 14.04 amd64 and also installed rails 3.2.16 but when I try to run a rails application I have this error that I didn't have in Ubuntu 12.04 amd64:

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.

If I use !optional have the next error:

"#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.

In the terminal server I get the following:

Started GET "/" for 127.0.0.1 at 2014-04-29 13:01:26 -0300

Answer 1

I had a problem with bootstrap-sass version. Solved it with:

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

Answer 2

You need to change ordering in application.css.scss as below:

/*
*= 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 is loaded with *= require_tree . statement and as you are using classes defined in other libraries you need to load them first so they can be used in schedules.css.scss
