覆盖rails中的bootstrap断点

Question

我正在使用sass-rails和bootstrap-sass宝石，我试图覆盖bootstrap中的断点。我想关闭所有屏幕的响应速度并将默认值设置为1200px。我尝试过一些方法，比如尝试使用appication.scss.css文件中的变量覆盖屏幕，但无济于事。

@import 'normalize';
@import "bootstrap-sprockets";
@import "bootstrap";

$screen-xs: 1200px;
$screen-sm: 1200px;
$screen-md: 1200px;
$screen-lg: 1200px;
$container-tablet:             (1200px + $grid-gutter-width) !default;
$container-sm:                 $container-tablet !default;
$container-desktop:            (1200px + $grid-gutter-width) !default;
$container-md:                 $container-desktop !default;
$container-large-desktop:      (1200px + $grid-gutter-width) !default;
$container-lg:                 $container-large-desktop !default;

$bgDefault      : #e6005c;
$bgHighlight    : #b30047;
$colDefault     : #ffffff;
$colHighlight   : #b8b8b8;
$fontSize       : 20px;
$dropDown       : false;

@font-face{
